Down (football)
A down is a period in which a play transpires in gridiron football. The down is a distinguishing characteristic of the game compared to other codes of football, but is synonymous with a "tackle" in rugby league. The team in possession of the football has a limited number of downs (four in American football, three in Canadian football) to advance ten yards or more towards their opponent's goal line. If they fail to advance that far, possession of the ball is turned over to the other team. In most situations, if a team reaches their final down they will punt to their opponent, which forces their opponent to begin their drive from further down the field; if they are in range, they might instead attempt to score a field goal. Description A down begins with a snap or free kick (such as a kickoff or safety kick), and ends when the ball or the player in possession of it is declared down by an official, a team scores, or the ball or player in possession of it leaves the field of pla ...

Quarterback
The quarterback (commonly abbreviated "QB"), colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive platoon and mostly line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack. Overview In modern American football, the starting quarterback is usually the leader of the offense, and their successes and failures can have a significant impact on the fortunes of their team. Accordingly, the quarterback is among the most glorified, scrutinized, and highest-paid positions in team sports. '' Bleacher Report'' describes the signing of a starting quarterback as a Catch- ...

1st & Ten (graphics System)
1st & Ten is a computer system that augments televised coverage of American football by inserting graphical elements on the field of play as if they were physically present; the inserted element stays fixed within the coordinates of the playing field, and obeys the visual rules of foreground objects occluding background objects. Developed by Sportvision and PVI Virtual Media Services, it is best known for generating and displaying a yellow first down line over a live broadcast of a football gamemaking it easier for viewers to follow play on the field. The line is not physically present on the field, and is seen only by the television audience. 1st & Ten is sometimes used generically to refer to the class of systems capable of adding first down lines and similar visual elements, and not just the Sportvision system. However, PVI's competing system is more accurately named L-VIS, for Live Video Insertion System. Over time, usage has evolved. Some football broadcasts change th ...

Coffin Corner (American Football)
The coffin corner refers to the corner of the playing field in American football just in front of the end zone, from about the 5-yard line to the goal line. A perfect coffin corner kick is one that goes out of bounds just before either orange pylon located in the front of the end zone. The punter tries to place the ball so that it lands out of bounds or is downed on the field by another member of the kicking team anywhere inside the 5-yard line without touching the goal line, thus forcing poor field position for the receiving team on their next offensive series. The term comes from the "coffin corner" found in Victorian houses (the slang and often refuted term for a decorative niche, or very small "corner", cut into the wall of a staircase landing), as the target area is very small. A high level of skill is required to execute such a punt, for if the kick is slightly too far into the end zone or if a member of the kicking team touches the goal line while maintaining possession of ...

Single (Canadian Football)
In Canadian football, a single (also called a single point, or ''rouge'') is a one-point score that is awarded for certain plays that involve the ball being kicked into the end zone and not returned from it. Rules A single is awarded when the ball is kicked into the end zone by any legal means—other than a convert (successful or not) or a successful field goal—and the receiving team does not return (or kick) the ball out of its end zone. A single is also scored if a kick—excluding kickoffs—goes out of bounds in the end zone without being touched. A single is indicated by the referee raising his right arm and index finger. After conceding a single, the receiving team is awarded possession of the ball at its 35-yard line (Football Canada rules) or 40-yard line (CFL rules). Singles are ''not'' awarded in the following situations: * if a ball is downed in the end zone after being intercepted in the end zone * if a ball is fumbled outside the end zone * if the kicked ball ...

Canadian Football
Canadian football () is a sport played in Canada in which two teams of 12 players each compete for territorial control of a field of play long and wide attempting to advance a pointed oval-shaped ball into the opposing team's scoring area ( end zone). In Canada, ''football'' may refer to Canadian football and American football collectively, or to either sport specifically, depending on context. Outside of Canada, the term Canadian football is used exclusively to describe this sport, even in the United States; the term '' gridiron football'' (or, more rarely, ''North American football'') is also used worldwide as well to refer to both sports collectively. The two sports have shared origins and are closely related but have some key differences. With the probable exception of a few minor and recent changes, for which there is circumstantial evidence to suggest the existence of at least informal cross-border collaboration, the modern rules of the two sports evolved independentl ...

Turnover On Downs
In gridiron football, a turnover on downs occurs when a team's offense has used all their downs but has not progressed downfield enough to earn another set of downs. The resulting turnover gives possession of the ball to the team currently on defense. In American football, both indoor and outdoor, a team has four opportunities (each opportunity is called a "down") to gain at least ten yards or to score. Any ground gained during each down short of these ten yards is kept for the next chance, and any ground lost must be regained in addition to the ten yards. Thus, if a team gains four yards on first down, it then has three chances to gain the six remaining yards, and if a team loses four yards on first down then it must gain a total of fourteen yards over the next three chances. If a team gains the required ten yards, it receives another four downs to gain another ten yards (an event called a "first down") or cross the goal line for a score. The same principles apply in Canadian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Touchback
In American football, a touchback is a ruling which is made and signaled by an official when the ball becomes dead on or behind a team's own goal line (i.e., in their end zone) and the opposing team gave the ball the momentum, or impetus, to travel over or across the goal line but did not have possession of the ball when it became dead. Since the 2018 season, touchbacks have also been awarded in college football on kickoffs that end in a fair catch by the receiving team between its own 25-yard line and goal line. Such impetus may be imparted by a kick, pass, fumble, or in certain instances by batting the ball. A touchback is not a play, but a result of events that may occur during a play. A touchback is the opposite of a safety with regard to impetus since a safety is scored when the ball becomes dead in a team's end zone after ''that team'' — the team whose end zone it is — caused the ball to cross the goal line. The result of a touchback is that the team in whose endzone t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forward Pass
In several forms of football, a forward pass is the throwing of the ball in the direction in which the offensive team is trying to move, towards the defensive team's goal line. The forward pass is one of the main distinguishers between gridiron football (American football and Canadian football) in which the play is legal and widespread, and rugby football (union and league) from which the North American games evolved, in which the play is illegal. The development of the forward pass in American football shows how the game has evolved from its rugby roots into the distinctive game it is today. Illegal and experimental forward passes had been attempted as early as 1876, but the first legal forward pass in American football took place in 1906, after a change in rules. Another change in rules occurred on January 18, 1951, which established that no center, tackle, or guard could receive a forward pass, unless such a player announces his intent to the referee beforehand that he w ...

Running Out The Clock
In sports, running out the clock (also known as running down the clock, stonewalling, killing the clock, chewing the clock, stalling, time-wasting (or timewasting) or eating clock) is the practice of a winning team allowing the clock to expire through a series of preselected plays, either to preserve a lead or hasten the end of a one-sided contest. Such measures expend time but do not otherwise have a tactical purpose. This is usually done by a team that is winning by a slim margin (or, occasionally, tied) near the end of a game, in order to reduce the time available for the opposing team to score. Generally, it is the opposite strategy of running up the score. The process of running out the clock generally involves low-risk, low-event play, intending to minimize the ability of the other team to interfere or counter. As this produces unexciting sport for spectators, many rulebooks attempt to counteract this; some include a time limit for completing a play, such as a play clock or ...

Playing Rugby League
Like most forms of modern football, rugby league football is played outdoors on a rectangular grass field with goals at each end that are to be attacked and defended by two opposing teams. The rules of rugby league have changed significantly over the decades since rugby football split into the league and union codes. This article details the modern form of the game and how it is generally played today, however rules do vary slightly between specific competitions. Basics Field A game of rugby league consists of two forty-minute halves, played by two teams on a rectangular grass field 120 metres long and 58–68 metres wide, depending on the individual ground. In the middle of the field is the 50-metre "halfway" line. Each side of the field, on either side of the 50-metre line, is identical. 10 metres from the 50-metre line is the 40-metre line, followed by the 30, 20, 10-metre and goal or "try" lines. This makes up 100 metres of field that is used for general play. At the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rugby Union
Rugby union, commonly known simply as rugby, is a close-contact team sport that originated at Rugby School in the first half of the 19th century. One of the two codes of rugby football, it is based on running with the ball in hand. In its most common form, a game is played between two teams of 15 players each, using an oval-shaped ball on a rectangular field called a pitch. The field has H-shaped goalposts at both ends. Rugby union is a popular sport around the world, played by people of all genders, ages and sizes. In 2014, there were more than 6 million people playing worldwide, of whom 2.36 million were registered players. World Rugby, previously called the International Rugby Football Board (IRFB) and the International Rugby Board (IRB), has been the governing body for rugby union since 1886, and currently has 101 countries as full members and 18 associate members. In 1845, the first laws were written by students attending Rugby School; other significant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
