Arrowhead Stadium has been in use since 1972 NFL season , and

224-422: A gridiron in appearance. Other major rule changes included a reduction of the field size to 110 by 53 + 1 ⁄ 3 yards (100.6 m × 48.8 m) and the adoption of a scoring system that awarded four points for a touchdown, two for a safety and a goal following a touchdown , and five for a goal from the field . Additionally, tackling below the waist was legalized, and a static line of scrimmage

336-403: A halftime period, and the first and third quarters are followed by a short break. Before the game starts, the referee and each team's captain meet at midfield for a coin toss . The visiting team can call either "heads" or "tails"; the winner of the toss chooses whether to receive or kick off the ball or which goal they wish to defend. They can defer their choice until the second half. Unless

448-461: A $ 102 million bond issue in 1967 to build a new sports complex with two stadiums. The original design called for construction of side-by-side baseball and football stadiums with a common roof that would roll between them. This design proved to be more complicated and expensive than originally thought and so was scrapped in favor of a more conventional open-air configuration. The Chiefs staff, led by team general manager Jack Steadman , helped develop

560-401: A 10-yard-long chain between them, are used to measure for a first down. The chain crew stays on the sidelines during the game, but if requested by the officials they will briefly bring the chains on to the field to measure. A typical chain crew will have at least three people—two members of the chain crew will hold either of the two sticks, while a third will hold the down marker. The down marker,

672-404: A 2–3 victory for the later on April 13, 2024 to accommodate for the large demand for tickets to see Inter Miami player Lionel Messi . It was Sporting's first game at the stadium since 2010 and attracted a crowd of 72,610, the fourth highest attended MLS event. Arrowhead Stadium was chosen as one of the 16 venues that will host games during the 2026 FIFA World Cup , which will be hosted jointly by

784-526: A 40-year sales tax increase to help fund the project. The Chiefs will consider options beyond renovating Arrowhead Stadium, including building a new stadium in the Kansas City area , including the Kansas side of the state line. From 1963 to 2008, the TD Pack Band was a mainstay at every Chiefs home game. The band was founded by trumpeter Tony DiPardo. The band was previously known as The Zing Band while

896-525: A PAT attempt or successful field goal, the scoring team must kick the ball off to the other team. A safety is scored when the ball carrier is tackled in the carrier's own end zone. Safeties are worth two points, which are awarded to the defense. In addition, the team that conceded the safety must kick the ball to the scoring team via a free kick . Football games are played on a rectangular field that measures 120 yards (110 m) long and 53 + 1 ⁄ 3 yards (48.8 m) wide. Lines marked along

1008-528: A charged timeout against Kansas City. Thank you for your cooperation." On October 13, 2013, in a game between the Chiefs and Oakland Raiders , the crowd at the stadium set a Guinness World Record for the loudest stadium, with 137.5 dB . That record would be broken by Seattle Seahawks fans at CenturyLink Field on December 2, 2013 at a home game against the New Orleans Saints . Seattle gained

1120-528: A common draft that would take place each year, and it instituted an annual World Championship game to be played between the champions of each league. This championship game began play at the end of the 1966 season. Once the merger was completed, it was no longer a championship game between two leagues and reverted to the NFL championship game, which came to be known as the Super Bowl . College football maintained

1232-598: A feat the Professional Football Researchers Association compared to "selling refrigerators to Eskimos ". Princeton, Harvard, Yale, and Columbia then agreed to intercollegiate play using a form of rugby union rules with a modified scoring system. These schools formed the Intercollegiate Football Association , although Yale did not join until 1879. Yale player Walter Camp , now regarded as

1344-585: A few hours' drive via Interstate 29 from Arrowhead, it made sense for a program which, at the time, one of the Big XII's lesser teams. The stadium also played host to the annual Fall Classic at Arrowhead , a Division II game that featured two nearby powerhouse programs in Northwest Missouri State University and Pittsburg State University . The 2004 game featured No. 1 Pittsburg State defeating No. 2 Northwest Missouri State in

1456-453: A field goal instead. A group of officials, the chain crew, keeps track of both the downs and the distance measurements. On television, a yellow line is electronically superimposed on the field to show the first down line to the viewing audience. There are two categories of kicks in football: scrimmage kicks, which can be executed by the offensive team on any down from behind or on the line of scrimmage, and free kicks. The free kicks are

1568-428: A game between Yale and Princeton, both teams used this strategy to maintain their undefeated records. Each team held the ball, gaining no ground, for an entire half, resulting in a 0–0 tie. This "block game" proved extremely unpopular with both teams' spectators and fans. A rule change was necessary to prevent this strategy from taking hold, and a reversion to the scrum was considered. However, Camp successfully proposed

1680-598: A game for the Allegheny Athletic Association against the Pittsburgh Athletic Club . This is the first recorded instance of a player being paid to participate in a game of American football , although many athletic clubs in the 1880s offered indirect benefits, such as helping players attain employment, giving out trophies or watches that players could pawn for money, or paying double in expense money. Despite these extra benefits,

1792-483: A kitchen, and a living room, to the design of the football stadium. To increase seating while limiting the stadium's footprint, the upper sections were placed at a steep incline which cannot be replicated in modern stadiums due to accessibility regulations. Deaton's design was implemented by the Kansas City architectural firm of Kivett & Myers . Arrowhead Stadium is considered by some to have had an influence on

1904-533: A large stick with a dial on it, is flipped after each play to indicate the current down and is typically moved to the approximate spot of the ball. The chain crew system has been used for over 100 years and is considered an accurate measure of distance, rarely subject to criticism from either side. Football is a full-contact sport, and injuries are relatively common. Most injuries occur during training sessions, particularly ones that involve contact between players. To try to prevent injuries, players are required to wear

2016-564: A league-suggested numbering scheme. Although the sport is played almost exclusively by men, women are eligible to play in high school, college, and professional football. No woman has ever played in the NFL, but women have played in high school and college football games. In 2018, 1,100 of the 225,000 players in Pop Warner Little Scholars youth football were girls, and around 11% of the 5.5 million Americans who report playing tackle football are female according to

2128-408: A long circumference of 28 to 28 + 1 ⁄ 2 inches (71 to 72 cm), and a short circumference of 21 to 21 + 1 ⁄ 4 inches (53 to 54 cm). In college and high school play the ball has a long axis of 10 + 7 ⁄ 8 to 11 + 7 ⁄ 16 inches (27.6 to 29.1 cm), a long circumference of 27 + 3 ⁄ 4 to 28 + 1 ⁄ 2 inches (70 to 72 cm), and

2240-420: A minimum of 10 feet (3.0 m) on high school fields. Goal posts are padded at the base, and orange ribbons are normally placed at the tip of each upright as indicators of wind strength and direction. The football itself is a prolate spheroid leather ball, similar to the balls used in rugby or Australian rules football . To contain the compressed air within it, a pig's bladder was commonly used before

2352-824: A naming rights deal between GEHA and the Chiefs. The agreement began at the start of the 2021 season and ends in January 2031 with the expiration of the leases for the Chiefs and Royals with Truman Sports Complex owner, the Jackson County Sports Complex Authority. When the Dallas Texans of the American Football League (AFL) relocated to Kansas City in 1963 and were rebranded as the Chiefs , they played their home games at Municipal Stadium . They originally shared

2464-704: A national champion of college football. The first was the Bowl Coalition , in place from 1992 to 1994. This was replaced in 1995 by the Bowl Alliance , which gave way to the Bowl Championship Series (BCS) in 1997. The BCS arrangement proved to be controversial , and was replaced in 2014 by the College Football Playoff (CFP). A football game is played between two teams of 11 players each. Playing with more on

2576-428: A pass hits the ground without a player having caught it. A forward pass can be legally attempted only if the passer is behind the line of scrimmage; only one forward pass can be attempted per down. As in rugby, players can also pass the ball backwards at any point during a play. In the NFL, a down also ends immediately if the runner's helmet comes off. The offense is given a series of four plays, known as downs . If

2688-427: A quarter ends, play continues until the down is completed. If certain fouls are committed during play while time has expired, the quarter may be extended through an untimed down . Games last longer than their defined length due to play stoppages—the average NFL game lasts slightly over three hours. Time in a football game is measured by the game clock. An operator is responsible for starting, stopping and operating

2800-414: A round ball that could not be picked up or carried. It could, however, be kicked or batted with the feet, hands, head, or sides, with the objective being to advance it into the opponent's goal. Rutgers won the game 6–4. Collegiate play continued for several years with games played using the rules of the host school. Representatives of Yale, Columbia , Princeton and Rutgers met on October 19, 1873, to create

2912-422: A rule in 1882 that limited each team to three downs , or tackles, to advance the ball 5 yards (4.6 m). Failure to advance the ball the required distance within those three downs would result in control of the ball being forfeited to the other team. This change effectively made American football a separate sport from rugby, and the resulting five-yard lines added to the field to measure distances made it resemble

3024-436: A secondary signal. Women can serve as officials; Sarah Thomas became the NFL's first female official in 2015. The seven officials (of a standard seven-man crew; lower levels of play up to the college level use fewer officials) on the field are each tasked with a different set of responsibilities: Another set of officials, the chain crew , are responsible for moving the chains. The chains, consisting of two large sticks with

3136-563: A set of equipment. At a minimum players must wear a football helmet and a set of shoulder pads , but individual leagues may require additional padding such as thigh pads and guards, knee pads, chest protectors, and mouthguards . Most injuries occur in the lower extremities, particularly in the knee, but a significant number also affect the upper extremities. The most common types of injuries are strains , sprains , bruises , fractures , dislocations , and concussions . Kivett %26 Myers Too Many Requests If you report this error to

3248-410: A short circumference of 20 + 3 ⁄ 4 to 21 + 1 ⁄ 4 inches (53 to 54 cm). Football games last for a total of 60 minutes in professional and college play and are divided into two halves of 30 minutes and four quarters of 15 minutes. High school football games are 48 minutes in length with two halves of 24 minutes and four quarters of 12 minutes. The two halves are separated by

3360-456: A standard set of rules for use by all schools. Teams were set at 20 players each, and fields of 400 by 250 feet (122 m × 76 m) were specified. Harvard abstained from the conference, as they favored a rugby-style game that allowed running with the ball. After playing McGill University using both American (known as "the Boston game ") for the first game and Canadian (rugby) rules for

3472-449: A tradition of postseason bowl games . Each bowl game was associated with a particular conference and earning a spot in a bowl game was the reward for winning a conference. This arrangement was profitable, but it tended to prevent the two top-ranked teams from meeting in a true national championship game, as they would normally be committed to the bowl games of their respective conferences. Several systems have been used since 1992 to determine

3584-425: Is called on the offense. There are two main ways the offense can advance the ball: running and passing . In a typical play, the center passes the ball backwards and between their legs to the quarterback in a process known as the snap . The quarterback then either hands the ball off to a running back, throws the ball, or runs with it. The play ends when the player with the ball is tackled or goes out-of-bounds or

3696-437: Is caught or recovered behind the line of scrimmage. If it is touched or recovered by the kicking team beyond this line, it becomes dead at the spot where it was touched. The kicking team is prohibited from interfering with the receiver's opportunity to catch the ball. The receiving team has the option of signaling for a fair catch , which prohibits the defense from blocking into or tackling the receiver. The play ends as soon as

3808-681: Is currently the oldest stadium in the AFC . It has a seating capacity of 76,416, making it the 25th-largest stadium in the United States and the fourth-largest NFL stadium. It is also the largest sports facility by capacity in the state of Missouri . A $ 375 million renovation was completed in 2010. The stadium is scheduled to host matches for the 2026 FIFA World Cup and has hosted college football games, as well as other soccer games. The stadium has been officially named GEHA Field at Arrowhead Stadium (pronounced G-E-H-A) since March 2021, following

3920-403: Is known as a two-point conversion . In general, the extra point is almost always successful, while the two-point conversion is a much riskier play with a higher probability of failure; accordingly, extra point attempts are far more common than two-point conversion attempts. A field goal (FG), worth three points, is scored when the ball is place kicked or drop kicked through the uprights and over

4032-407: Is responsible for all kicking plays. The special teams unit of the team in control of the ball tries to execute field goal (FG) attempts, punts , and kickoffs , while the opposing team's unit will aim to block or return them. Three positions are specific to the field goal and PAT (point-after-touchdown) unit: the placekicker (K or PK), holder (H), and long snapper (LS). The long snapper's job

4144-421: Is to block members of the defensive line from tackling the ball carrier on running plays or sacking the quarterback on passing plays. The leader of the offensive line is the center, who is responsible for snapping the ball to the quarterback, blocking, and for making sure that the other linemen do their jobs during the play. On either side of the center are the guards (G), while tackles (T) line up outside

4256-437: Is to snap the football to the holder, who will catch and position it for the placekicker. There is not usually a holder on kickoffs, because the ball is kicked off a tee; however, a holder may be used in certain situations, such as if wind is preventing the ball from remaining upright on the tee. The player on the receiving team who catches the ball is known as the kickoff returner (KR). The positions specific to punt plays are

4368-607: The 1958 NFL Championship game between the Baltimore Colts and the New York Giants , still referred to as the "Greatest Game Ever Played". The game, a 23–17 overtime victory by the Colts, was seen by millions of television viewers and had a major influence on the popularity of the sport. This, along with the innovations introduced by the new American Football League (AFL) in the early 1960s, helped football to become

4480-711: The Border War between the Kansas Jayhawks and the Missouri Tigers . The 2007 game between the No. 2 Jayhawks and No. 3 Tigers , dubbed "Armageddon at Arrowhead" by media and fans, drew the second largest crowd in stadium history, at 80,537, with the Tigers winning 36-28. Kansas also played Oklahoma at Arrowhead in 2005. Missouri played Arkansas State in 2005 and BYU in 2015 as home games at Arrowhead. Missouri

4592-666: The Pro Bowl . Due to an ice storm and brutally cold temperatures the week leading up to the game, the game's participants worked out at the facilities of the San Diego Chargers . On game day, the temperature soared to 41 °F (5 °C), melting most of the ice and snow that accumulated during the week. The AFC defeated the NFC , 15–13. In 1984, the Jackson County Sports Authority re-evaluated

4704-411: The kickoff , which starts the first and third quarters and overtime and follows a try attempt or a successful field goal; the safety kick follows a safety. On a kickoff, the ball is placed at the 35-yard line of the kicking team in professional and college play and at the 40-yard line in high school play. The ball may be drop kicked or place kicked. If a place kick is chosen, the ball can be placed on

4816-407: The punter (P), long snapper, upback , and gunner . The long snapper snaps the football directly to the punter, who then drops and kicks it before it hits the ground. Gunners line up split outside the line and race down the field, aiming to tackle the punt returner (PR)—the player who catches the punt. Upbacks line up a short distance behind the line of scrimmage, providing additional protection to

4928-471: The "Father of American Football", secured rule changes in 1880 that reduced the size of each team from 15 to 11 players and instituted the snap to replace the chaotic and inconsistent scrum . While the game between Rutgers and Princeton is commonly considered the first American football game, several years prior in 1862, the Oneida Football Club formed as the oldest known football club in

5040-520: The "Father of American Football", established the snap , the line of scrimmage , eleven-player teams, and the concept of downs. Later rule changes legalized the forward pass , created the neutral zone , and specified the size and shape of the football. The sport is closely related to Canadian football , which evolved in parallel with and at the same time as the American game, although its rules were developed independently from those of Camp. Most of

5152-519: The 2002 Eddie Robinson Classic, while Kansas State played Cal in the 2003 Eddie Robinson Classic. In 1998, Oklahoma State moved its scheduled home game vs. Nebraska to Arrowhead. The move was done to boost attendance and revenue: Lewis Field in Stillwater sat less than 50,000 fans at that time, the Huskers were the defending national champions, and with many Nebraska supporters living only

5264-548: The 2010 season. In 2019, the Chiefs announced multiple renovations for the 2020 season, which included replaced seats in the lower level, a new video display on the East end, and locker room upgrades. In February 2024, the Chiefs announced additional plans to renovate the stadium starting in 2027, which would further increase the seating capacity along with other upgrades; however, those plans were shelved in April when voters rejected

5376-459: The A's was a shock to local sports fans an community leaders and there was a growing sense that government subsidy of a stadium complex would be necessary to keep major league baseball and professional football in the city. When Kansas City was unable to find a suitable location for a new stadium, Jackson County stepped in and offered a location on the eastern edge of town near the interchange of Interstate 70 and Interstate 435 . Voters approved

5488-542: The AFL New York Jets signed rookie Joe Namath to a then-record $ 437,000 contract (equivalent to $ 4.23 million in 2023). A five-year, $ 40 million NBC television contract followed, which helped to sustain the young league. The bidding war for players ended in 1966 when NFL owners approached the AFL regarding a merger, and the two leagues agreed on one that took full effect in 1970. This agreement provided for

5600-584: The Chiefs played at Municipal Stadium . DiPardo, nicknamed "Mr. Music", was born in St. Louis, Missouri on August 15, 1912. DiPardo wrote songs about the team such as "The Chiefs are on the Warpath" and "The Hank Stram Polka". DiPardo received a Super Bowl ring for the Chiefs' victory in Super Bowl IV . DiPardo died in 2011. American football American football , referred to simply as football in

5712-582: The FCS and 85 scholarship players in the FBS, respectively. Individual players in a football game must be designated with a uniform number between 1 and 99, though some teams may "retire" certain numbers , making them unavailable to players. NFL teams are required to number their players by a league-approved numbering system, and any exceptions must be approved by the commissioner . NCAA and NFHS teams are "strongly advised" to number their offensive players according to

5824-650: The Hunt family, which originally had intended to donate $ 75 million. The renovated stadium features the Chiefs Hall of Honor, a tribute to Lamar Hunt , and "horizon level" seating in which luxury suite owners sit outdoors. Reconstruction for the stadiums started on October 3, 2007. Refurbishment of nearby Kauffman Stadium, home to the Kansas City Royals baseball team, commenced at that time, and both completely-refurbished stadiums were ready for play by

5936-552: The Miami Dolphins, the team that defeated the Chiefs in the final game football game at Municipal Stadium, a double overtime playoff game on Christmas Day 1971 that is still the longest game in NFL history. On November 5, 1972, 82,094 people (the largest crowd to see a game at Arrowhead Stadium) saw the Chiefs defeat the Oakland Raiders , 27-14, to mark their first regular-season victory in their new home. In 1973,

6048-456: The Sports and Fitness Industry Association. The role of the offensive unit is to advance the football down the field with the ultimate goal of scoring a touchdown .

An offensive formation is considered illegal if there are more than four players in the backfield or fewer than five players numbered 50–79 on

6160-586: The United Kingdom, Ireland, New Zealand, and Australia. American football evolved from the sports of rugby and soccer . Rugby, like American football, is a sport in which two competing teams vie for control of a ball, which can be kicked through a set of goalposts or run into the opponent's goal area to score points. What is considered to be the first American football game was played on November 6, 1869 , between Rutgers and Princeton , two college teams. They consisted of 25 players per team and used

6272-405: The United States and Canada and also known as gridiron football , is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end.

6384-505: The United States, Canada and Mexico . The stadium will require renovations. Kansas City, Missouri mayor Quinton Lucas estimated the cost of the necessary renovations at $ 50 million. The stadium will host six matches, including four group stage matches, one Round of 32 match, and one quarterfinal match. On April 4, 2006, Jackson County voters approved a tax increase to finance municipal bonds to pay for $ 850 million in renovations to Arrowhead Stadium and nearby Kauffman Stadium . Before

6496-455: The United States. The team consisted of graduates of Boston's elite preparatory schools and played from 1862 to 1865. The introduction of the snap resulted in an unexpected consequence. Before the snap, the strategy had been to punt if a scrum resulted in bad field position. However, a group of Princeton players realized that, as the snap was uncontested, they could now hold the ball indefinitely to prevent their opponent from scoring. In 1881, in

6608-554: The United States: official time was kept on a scoreboard clock rather than on a watch in the referee's pocket, as the NFL did; optional two-point conversions by pass or run after touchdowns; names on the jerseys of players; and several others, including expansion of the role of minority players, actively recruited by the league in contrast to the NFL. The AFL also signed several star college players who had also been drafted by NFL teams. Competition for players heated up in 1965, when

6720-460: The advent of artificial rubber inside the leather outer shell to sustain crushing forces . At all levels of play, the football is inflated to 12 + 1 ⁄ 2 to 13 + 1 ⁄ 2  psi (86 to 93 kPa), or just under one atmosphere, and weighs 14 to 15 ounces (400 to 430 g); beyond that, the exact dimensions vary slightly. In professional play the ball has a long axis of 11 to 11 + 1 ⁄ 4 inches (28 to 29 cm),

6832-435: The ball is caught, and the ball may not be advanced. Officials are responsible for enforcing game rules and monitoring the clock.

6944-478: The ball off, throws it, or runs with it. The primary role of the halfback, also known as the running back or tailback, is to carry the ball on running plays. Halfbacks may also serve as receivers. Fullbacks tend to be larger than halfbacks and function primarily as blockers, but they are sometimes used as runners in short-yardage or goal-line situations. They are seldom used as receivers. The offensive line (OL) consists of several players whose primary function

7056-467: The ball through the opponent's goalposts for a field goal . The team with the most points at the end of the game wins. American football evolved in the United States, originating from the sports of soccer and rugby . The first American football game was played on November 6, 1869 , between two college teams, Rutgers and Princeton , using rules based on the rules of soccer at the time. A set of rule changes drawn up from 1880 onward by Walter Camp ,

7168-402: The bond election, the NFL announced it would award hosting rights of a future Super Bowl to Kansas City provided it would have a climate-controlled stadium. With the passing of the stadium bill, the Chiefs signed a new lease which ensures that the team will remain at Arrowhead until at least 2031. However, a second bond issue to build the rolling roof shared with Kauffman Stadium that was part of

7280-428: The complex. Construction began in 1968. The original two-stadium concept was initially designed by Denver architect Charles Deaton and Steadman. The baseball and football stadiums have a very different appearance, but share utilities, parking, and underground storage. Plans to have covered stadiums were dropped, leaving two open-air stadiums. Lamar Hunt included an owner's suite, complete with three bedrooms, bathrooms,

7392-559: The concept of a fabric dome. The concept was disregarded as being unnecessary and financially impractical. Arrowhead hosted the Drum Corps International World Championships in 1988 and 1989. In 1991, two Diamond Vision screens shaped as footballs were installed. In 1994, other improvements were made and natural grass playing surface was installed, replacing the original artificial AstroTurf playing field. In 2009, Arrowhead Stadium completed

7504-446: The corners of the end zones to comply with FIFA field regulations . Space would also have to be made for hospitality and media seating (outside of the stadium's already existing press box). The field will also undergo improvement to its ventilation system.

7616-413: The crossbars of the defense's goalposts. In practice, almost all field goal attempts are done via place kick. While drop kicks were common in the early days of the sport, the shape of modern footballs makes it difficult to reliably drop kick the ball. The last successful scoring play by drop kick in the NFL was accomplished in 2006; prior to that, the last successful drop kick had been made in 1941. After

7728-399: The defense is to prevent the offense from scoring by tackling the ball carrier or by forcing turnovers . Turnovers include interceptions (a defender catching a forward pass intended for the offense) and forced fumbles (taking possession of the ball from the ball-carrier). The defensive line (DL) consists of defensive ends (DE) and defensive tackles (DT). Defensive ends line up on

7840-430: The defensive backfield. They are divided into two types: middle linebackers (MLB) and outside linebackers (OLB). Linebackers tend to serve as the defensive leaders and call the defensive plays, given their vantage point of the offensive backfield. Their roles include defending the run, pressuring the quarterback, and tackling backs, wide receivers, and tight ends in the passing game. The defensive backfield , often called

7952-425: The design of several future NFL stadiums. Construction of the stadium was a joint venture Sharp-Kidde- Webb construction firms. Construction on Arrowhead Stadium was completed in time for the 1972 season . On August 12, 1972, the Chiefs defeated the St. Louis Cardinals 24–14 in the first preseason game at Arrowhead Stadium. In the first regular season game at Arrowhead Stadium in 1972, the Chiefs were defeated by

8064-472: The ends and sides of the field are known as the end lines and sidelines . Goal lines are marked 10 yards (9.1 m) inward from each end line. Weighted pylons are placed the sidelines on the inside corner of the intersections with the goal lines and end lines. White markings on the field identify the distance from the end zone. Inbound lines, or hash marks , are short parallel lines that mark off 1-yard (0.91 m) increments. Yard lines , which can run

8176-404: The ends of the line, while defensive tackles line up inside, between the defensive ends. The primary responsibilities of defensive ends and defensive tackles are to stop running plays on the outside and inside, respectively, to pressure the quarterback on passing plays, and to occupy the line so that the linebackers can break through. Linebackers line up behind the defensive line but in front of

8288-561: The features that distinguish American football from rugby and soccer are also present in Canadian football. The two sports are considered the primary variants of gridiron football . American football is the most popular sport in the United States in terms of broadcast viewership audience.

As of 2022 , nearly 1.04 million high-school athletes play

8400-468: The field is punishable by a penalty. Teams may substitute any number of their players between downs; this "platoon" system replaced the original system, which featured limited substitution rules, and has resulted in teams utilizing specialized offensive, defensive and special teams units. The number of players allowed on an active roster varies by league; the NFL has a 53-man roster, while NCAA Division I allows teams to have 63 scholarship players in

8512-454: The field was shortened to 100 yards (91 m) long, two 10-yard-long (9.1 m) end zones were created, and teams were given four downs instead of three to advance the ball 10 yards (9.1 m). The roughing the passer penalty was implemented in 1914, and eligible players were first allowed to catch the ball anywhere on the field in 1918. On November 12, 1892, Pudge Heffelfinger was paid $ 500 (equivalent to $ 16,956 in 2023) to play

8624-629: The formation of the Intercollegiate Athletic Association of the United States, later renamed the National Collegiate Athletic Association (NCAA). The legal forward pass was introduced in 1906, although its effect was initially minimal due to the restrictions placed on its use. The idea of a 40-yard-wider field was opposed by Harvard due to the size of the new Harvard Stadium . Other rule changes introduced that year included

8736-419: The game clock based on the direction of the appropriate official . A separate play clock is used to show the amount of time within which the offense must initiate a play. The play clock is set to 25 seconds after certain administrative stoppages in play and to 40 seconds when play is proceeding without such stoppages. If the offense fails to start a play before the play clock reads "00", a delay of game foul

8848-409: The game had a strict sense of amateurism at the time, and direct payment to players was frowned upon, if not prohibited outright. Over time, professional play became increasingly common, and with it came rising salaries and unpredictable player movement, as well as the illegal payment of college players who were still in school. The National Football League (NFL), a group of professional teams that

8960-443: The ground or a tee; a holder may be used in either case. On a safety kick, the kicking team kicks the ball from their own 20-yard line. They can punt, drop kick or place kick the ball, but a tee may not be used in professional play. Any member of the receiving team may catch or advance the ball. The ball may be recovered by the kicking team once it has gone at least ten yards and has touched the ground or has been touched by any member of

9072-434: The guards. The principal receivers are the wide receivers (WR) and the tight ends (TE). Wide receivers line up on or near the line of scrimmage, split outside the line. The main goal of the wide receiver is to catch passes thrown by the quarterback, but they may also function as decoys or as blockers during running plays. Tight ends line up outside the tackles and function both as receivers and as blockers. The role of

9184-412: The installation of a multimillion-dollar integrated system from Daktronics . Two high definition video displays were retrofitted into the existing football-shaped displays in both end zones. Approximately 1,625 feet (495 m) of digital ribbon board technology was also installed in the stadium. In 2013, Arrowhead Stadium started using a new playing surface known as NorthBridge Bermudagrass. The reason

9296-506: The most popular sport in the United States by the mid-1960s. The rival AFL arose in 1960 and challenged the NFL's dominance. The AFL began in relative obscurity but eventually thrived, with an initial television contract with the ABC television network. The AFL's existence forced the conservative NFL to expand to Dallas and Minnesota in an attempt to destroy the new league. Meanwhile, the AFL introduced many new features to professional football in

9408-429: The offense advances ten or more yards in the four downs, they are awarded a new set of four downs. If they fail to advance ten yards, possession of the football is turned over to the defense. In most situations, if the offense reaches their fourth down they will punt the ball to the other team, which forces them to begin their drive from farther down the field; if they are in field goal range , they might attempt to score

9520-410: The offense's advance and to take control of the ball for themselves. The offense must advance the ball at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive . Points are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking

9632-429: The offensive line. Players can line up temporarily in a position whose eligibility is different from what their number permits as long as they report the change immediately to the referee, who then informs the defensive team of the change. Neither team's players, except the center (C), are allowed to line up in or cross the neutral zone until the ball is snapped. Interior offensive linemen are not allowed to move until

9744-470: The only Division II game to feature the nation's top two teams playing in the regular season finale. For the 2024 season, Kansas played four conference home games at the stadium due to renovations at their stadium . *Win vacated With the formation of Major League Soccer in 1996, Arrowhead Stadium became home to the Kansas City Wiz, now known as Sporting Kansas City . After the 1996 season,

9856-572: The original 1967 stadium plan was defeated by voters, and Kansas City chose to withdraw its request to host Super Bowl XLIX in 2015; the game was played at the University of Phoenix Stadium (now State Farm Stadium) in Glendale, Arizona . On August 15, 2007, the Chiefs announced final plans for the renovated Arrowhead Stadium, which would cost $ 375 million. The cost to the city was reduced by $ 50 million thanks to an additional payment by

9968-445: The plane of the two end lines. The crossbar of these posts is 10 feet (3.0 m) above the ground, with vertical uprights at the end of the crossbar 18 feet 6 inches (5.64 m) apart for professional and collegiate play, and 23 feet 4 inches (7.11 m) apart for high school play. The uprights extend vertically 35 feet (11 m) on professional fields, a minimum of 10 yards (9.1 m) on college fields, and

10080-451: The point(s)-after-touchdown (PAT) or conversion, which is a single scoring opportunity. This is generally attempted from the two- or three-yard line, depending on the level of play. If the PAT is scored by a place kick or drop kick through the goal posts, it is worth one point, typically called the extra point. If the PAT is scored by what would normally be a touchdown, it is worth two points; this

10192-422: The punter. In football, the winner is the team that has scored more points at the end of the game. There are multiple ways to score in a football game. The touchdown (TD), worth six points, is the most valuable scoring play in American football. A touchdown is scored when a live ball is advanced into, caught, or recovered in the opposing team's end zone. The scoring team then attempts a try, more commonly known as

10304-401: The receiving team. The three types of scrimmage kicks are place kicks, drop kicks, and punts. Only place kicks and drop kicks can score points. The place kick is the standard method used to score points, because the pointy shape of the football makes it difficult to reliably drop kick. Once the ball has been kicked from a scrimmage kick, it can be advanced by the kicking team only if it

10416-585: The record by reaching a noise level of 137.6 decibels. The Chiefs reclaimed the title on September 29, 2014 in a Monday Night Football game against the New England Patriots , hitting 142.2 decibels. Arrowhead Stadium has hosted five Big 12 Conference football championship games : Kansas State versus Oklahoma in 2000 and 2003, Colorado versus Oklahoma in 2004, Nebraska versus Oklahoma on December 2, 2006, and Missouri versus Oklahoma in 2008. From 2007 to 2011, Arrowhead Stadium hosted

10528-439: The reduction of playing time from 70 to 60 minutes and an increase of the distance required for a first down from 5 to 10 yards (4.6 to 9.1 m). To reduce infighting and dirty play between teams, the neutral zone was created along the width of the football before the snap. Scoring was also adjusted: points awarded for field goals were reduced to three in 1909 and points for touchdowns were raised to six in 1912. Also in 1912,

10640-542: The rulebook for the 1876 college football season , when the sport first shifted from soccer-style rules to rugby-style rules. Although it could easily have been called "rugby" at this point, Harvard, one of the primary proponents of the rugby-style game, compromised and did not request the name of the sport be changed to "rugby". The terms " gridiron " or "American football" are favored in English-speaking countries where other types of football are popular, such as

10752-457: The second one, the Harvard players preferred the Canadian style of having only 11 men on the field, running the ball without having to be chased by an opponent, the forward pass, tackling, and using an oblong instead of a round ball. An 1875 Harvard–Yale game played under rugby-style rules was observed by two Princeton athletes who were impressed by it. They introduced the sport to Princeton,

10864-503: The secondary, consists of cornerbacks (CB) and safeties (S). Safeties are themselves divided into free safeties (FS) and strong safeties (SS). Cornerbacks line up outside the defensive formation, typically opposite a receiver to be able to cover them. Safeties line up between the cornerbacks but farther back in the secondary. Safeties tend to be viewed as "the last line of defense" and are responsible for stopping deep passing plays as well as breakout running plays. The special teams unit

10976-411: The snap of the ball. The main backfield positions are the quarterback (QB), halfback/tailback (HB/TB), and fullback (FB). The quarterback is the leader of the offense. Either the quarterback or a coach calls the plays. Quarterbacks typically inform the rest of the offense of the play in the huddle before the team lines up. The quarterback lines up behind the center to take the snap and then hands

11088-531: The sport in the U.S., with another 81,000 college athletes in the NCAA and the NAIA . The National Football League (NFL) has the highest average attendance of any professional sports league in the world .

In 2022, the league had an annual revenue of around $ 18.6 billion, making it the most valuable sports league in

11200-525: The stadium was the first in the NFL to include arrows on the yard markers to indicate the nearer goal line. (Initially, they resembled little Indian arrowheads.) This practice would eventually spread to the other NFL stadiums as the 1970s progressed, finally becoming mandatory league-wide in the 1978 season (after being used in Super Bowl XII ), and become almost near-universal at lower levels of football. On January 20, 1974, Arrowhead Stadium hosted

11312-637: The stadium with the Kansas City Athletics of Major League Baseball , but the Athletics relocated to Oakland, California, after the 1967 season, with the expansion Kansas City Royals being added in 1969.

The loss of

11424-415: The team made the switch was due to the cold weather tolerance, rapid recovery and aggressive rooting. In 2021, the Chiefs sold the naming rights for Arrowhead Stadium to GEHA , renaming it GEHA Field at Arrowhead Stadium. Arrowhead Stadium will be one of the hosts for the 2026 FIFA World Cup and it is scheduled to undergo small renovations in the years ahead. Seating capacity is expected to be reduced in

11536-548: The team was renamed the Wizards. They left after the 2007 season, after being sold by the Hunt Family to On Goal, LLC , once their lease ended. This was also beneficial so that construction work on Arrowhead Stadium's renovation could take place during the NFL off-season. The Wizards moved to CommunityAmerica Ballpark, now known as Legends Field , in 2008 and did not return to Arrowhead except for one friendly. That friendly

11648-499: The time was played at the collegiate level . The upstart NFL received a boost to its legitimacy in 1925, however, when an NFL team, the Pottsville Maroons , defeated a team of Notre Dame all-stars in an exhibition game . A greater emphasis on the passing game helped professional football to distinguish itself further from the college game during the late 1930s. Football, in general, became increasingly popular following

11760-411: The width of the field, are marked every 5 yards (4.6 m). A one-yard-wide line is placed at each end of the field; this line is marked at the center of the two-yard line in professional play and at the three-yard line in college play. Numerals that display the distance from the closest goal line in yards are placed on both sides of the field every ten yards. Goalposts are located at the center of

11872-408: The winning team decides to defer, the losing team chooses the option the winning team did not select—to receive, kick, or select a goal to defend to begin the second half. Most teams choose to receive or defer, because choosing to kick the ball to start the game allows the other team to choose which goal to defend. Teams switch goals following the first and third quarters. If a down is in progress when

11984-402: The world. Other professional and amateur leagues exist worldwide, but the sport does not have the international popularity of other American sports like baseball or basketball ; the sport maintains a growing following in the rest of North America, Europe, Brazil, and Japan. In the United States, American football is referred to as "football". The term "football" was officially established in

12096-471: Was approved; however, the sales tax extension failed to pass. In 1990 in a game against the Denver Broncos , the Chiefs were threatened with a penalty if the crowd would not quiet down. After John Elway was backed up to his own goal line and unable to even run a play he quickly spoke to referee Gordon McCarter . After listening to Elway, McCarter said "Any further crowd-noise problem will result in

12208-520: Was instituted. Despite these new rules, football remained a violent sport. Dangerous mass-formations like the flying wedge resulted in serious injuries and deaths. A 1905 peak of 19 fatalities nationwide resulted in a threat by President Theodore Roosevelt to abolish the game unless major changes were made. In response, 62 colleges and universities met in New York City to discuss rule changes on December 28, 1905. These proceedings resulted in

12320-535: Was originally established in 1920 as the American Professional Football Association, aimed to solve these problems. This new league's stated goals included an end to bidding wars over players, prevention of the use of college players, and abolition of the practice of paying players to leave another team. By 1922, the NFL had established itself as America's premier professional football league. The dominant form of football at

12432-685: Was played on July 25, 2010; the Wizards faced Manchester United at Arrowhead Stadium for the English team's third preseason friendly in America during 2011.
