Play Clock
A play clock, also called a delay-of-game timer, is a countdown clock intended to speed up the pace of the game in gridiron football. The offensive team must put the ball in play by either snapping the ball during a scrimmage down or kicking the ball during a free kick down before the time expires, or else they will be assessed a 5-yard ''delay of game'' (American football) or ''time count violation'' (Canadian football; that code's "delay of game" is a different infraction) penalty. If a visible clock is not available or not functioning, game officials on the field will use a stopwatch or other similar device to enforce the rule. In all levels of Canadian football, the offensive team must run a play within 20 seconds of the referee whistling the play in; in amateur American football, teams have 25 seconds from the time the ball is declared ready for play. In the NFL, teams have 40 seconds timed from the end of the previous down. Before 2008, in college football, the play clock wa ...

Offensive Team
In American football, the specific role that a player takes on the field is referred to as their "position". Under the modern rules of American football, both teams are allowed 11 players on the field at one time and have "unlimited free substitutions", meaning that they may change any number of players during any "dead ball" situation. This has resulted in the development of three task-specific "platoons" of players within any single team: the offense (the team with possession of the ball, which is trying to score), the defense (the team trying to prevent the other team from scoring, and to take the ball from them), and the so-called 'special teams' (who play in all kicking situations). Within these three separate "platoons", various positions exist depending on the jobs that the players are doing. Offense In American football, the offense is the team that has possession of the ball and is advancing toward the opponent's end zone to score points. The eleven players of the offen ...

Snap (football)
A snap (colloquially called a "hike", "snapback", or "pass from center") is the backward passing of the ball in gridiron football at the start of play from scrimmage. Action The ball begins on the ground with its long axis parallel to the sidelines of the field, its ends marking each team's line of scrimmage in American football; in Canadian football, the line of scrimmage of the team without the ball is 1 yard past their side of the ball. The player snapping the ball (known officially as the "snapper" in rule books) delivers the ball to another player, and that action is the snap. The snapper may hand, throw, or even roll the ball to the other player. The snap must be a quick and continuous movement of the ball by one or both hands of the snapper, and the ball must leave the snapper's hands. The various rules codes have additional requirements, all of which have the effect of requiring the ball to go backward. The snapper almost always passes the ball between his legs, but on ...

XFL (2001)
The XFL was a professional American football league that played its only season in 2001. The XFL was operated as a joint venture between the WWE, World Wrestling Federation (WWF, now WWE) and NBC. The XFL was conceived as an outdoor football league that would begin play immediately after the National Football League season ended, to take advantage of the perceived lingering public desire to watch football after the NFL and college football seasons conclude. It was promoted as having fewer rules to encourage rougher play than other major leagues, while its telecasts featured sports entertainment elements inspired by professional wrestling (and in particular, the WWF's then-current "Attitude Era"), including heat (wrestling), heat and kayfabe, and suggestively-dressed cheerleaders. Commentary crews also featured WWF commentators (such as Jesse Ventura, Jim Ross, and Jerry Lawler) joined by sportscasters and veteran football players. Despite the wrestling influence, the games and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alliance Of American Football
The Alliance of American Football (AAF) was a professional American football minor league. The AAF consisted of eight centrally owned and operated teams in the southern and western United States, seven of which were located in metropolitan areas with at least one major professional sports franchise. Founded by Charlie Ebersol and Bill Polian in 2018, the AAF began play on February 9, 2019. The league was scheduled to have a 10-week regular season and conclude with a championship game on April 27. After eight weeks of play, however, the league's football operations were suspended by controlling owner Thomas Dundon on April 2. Two days later, the AAF allowed players to leave their contracts to sign with NFL teams. The AAF filed for Chapter 7 bankruptcy on April 17, 2019, with the league's sole season left incomplete. History Charlie Ebersol, son of former NBC executive and XFL co-founder Dick Ebersol, was inspired to create the AAF in late 2016 after producing the documenta ...

XFL (2020)
The XFL is a professional American football minor league consisting of eight teams located across the United States in mid-sized to major markets served by at least one other major professional sports team. Seasons run from February to April, with each team playing a ten-game regular season, and four progressing to the playoffs to crown a season champion. It is headquartered in Arlington, Texas. The league was founded by former WWE executive Vince McMahon in 2018, as a reboot and successor to the league of the same name he founded in 2001. McMahon re-founded the XFL to create a league with fewer off-field controversies and faster, simpler play compared to the National Football League (NFL), as well as one without the professional wrestling–inspired features and entertainment elements of its predecessor. The league and its teams were originally owned by McMahon's Alpha Entertainment. After only five weeks of play in its inaugural 2020 season, the league's operations slowl ...

Arena Football
Indoor American football, or arena football, is a variation of gridiron football played at ice hockey-sized indoor arenas. While varying in details from league to league, the rules of indoor football are designed to allow for play in a smaller arena. It is distinct from traditional American or Canadian football played in larger domed or open-air stadiums, although several early college football games contested on full-sized or nearly full-sized fields at Chicago Coliseum (1890s) and Atlantic City Convention Center (1930s and 1960s) helped to show that football could be played as an indoor game. History Early history The first demonstration of football on a small field was actually played outdoors at the original open-air Madison Square Garden. Using nine-man sides, Pennsylvania defeated Rutgers 10–0 at the annual meeting of the Amateur Athletic Union on January 16, 1889. The first documented indoor football game was an exhibition between the Springfield YMCA Training Scho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canadian Football League
The Canadian Football League (CFL; french: Ligue canadienne de football—LCF) is a professional sports league in Canada. The CFL is the highest level of competition in Canadian football. The league consists of nine teams, each located in a city in Canada. They are divided into two divisions: four teams in the East Division and five teams in the West Division. As of 2022, it features a 21-week regular season in which each team plays 18 games with three bye weeks. This season traditionally runs from mid-June to early November. Following the regular season, six teams compete in the league's three-week playoffs, which culminate in the Grey Cup championship game in late November. The Grey Cup is one of Canada's largest annual sports and television events. The CFL was officially named on January 19, 1958, upon the merger between the Interprovincial Rugby Football Union or "Big Four" (founded in 1907) and the Western Interprovincial Football Union (founded in 1936).

Three-minute Warning (football)
In Canadian football, the three-minute warning is given when three minutes of game time remain on the game clock in the first and second halves of a game. (If the football is in play when the clock reaches 3:00, the three-minute warning is given immediately after the ball is declared dead.) The three-minute warning stops the game clock in all cases. It is the Canadian football equivalent of the two-minute warning in the American game. Rule changes after the warning * The game clock stops whenever the ball is dead. * The game clock starts on the snap after any kickoff, kick from scrimmage, open field kick, change of possession, incomplete forward pass, score, or the ball being carried out of bounds, accepted penalty, or fouls on both teams. If a foul is declined, the non-offending team can choose to start the game clock on the snap. * The game clock does not run on convert attempts. * Since the 2006 CFL season, CFL teams cannot use instant replay challenges to dispute rulings duri ...

Clock Management
In gridiron football, clock management is an aspect of game strategy that focuses on the game clock and/or play clock to achieve a desired result, typically near the end of a match. Depending on the game situation, clock management may entail playing in a manner that either slows or quickens the time elapsed from the game clock, to either extend the match or hasten its end. When the desired outcome is to end the match quicker, it is analogous to "running out the clock" (and associated counter-tactics) seen in many sports. Clock management strategies are a significant part of American football, where an elaborate set of rules dictates when the game clock stops between downs, and when it continues to run. In American football Rules for the game clock Upon kickoff, the clock is started when a member of the receiving team touches the ball, or, if the member of the receiving team touches the ball in their end zone, carries the ball out of the end zone. The clock is stopped when the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Back Judge
In gridiron football, an official is a person who has responsibility in enforcing the rules and maintaining the order of the game. During professional and most college football games, seven officials operate on the field. Since 2015, Division I college football conferences have used eight game officials, the Alliance of American Football (AAF) in its only season in 2019 and the 2020 version of the XFL have used eight game officials. College games outside the Division I level use six or seven officials. Arena football, high school football, and other levels of football have other officiating systems, which use less than the standard seven officials. High school football played under the National Federation of State High School Associations (NFHS) rules typically use five officials for varsity and 3, 4, or 5 for non-varsity games. Football officials are commonly, but incorrectly, referred to collectively as referees, but each position has specific duties and a specific name: Common ...

Pitch Clock
A pitch clock is used in college baseball and Minor League Baseball to limit the amount of time a pitcher uses before he throws the ball to the hitter. This is one measure that has accelerated the pace of play. Major League Baseball (MLB) will begin using a pitch clock in the season. Examples In college baseball, the Southeastern Conference experimented with using pitch clocks in 2010. Pitchers were given twenty seconds to throw the pitch, or a ball would be added to the count. Similarly, a batter stepping out of the batter's box with less than five seconds on the clock will be assessed an additional strike. After the 2010 season, the National Collegiate Athletic Association sought to make the pitch clocks mandatory, and instituted it for the 2011 college baseball season, but only for when there are no runners on base. Pitch clocks made their professional debut in the Arizona Fall League in 2014. On January 15, 2015, Major League Baseball (MLB) announced it would institute a 2 ...
