Pass Interference
In American and Canadian football, pass interference (PI) is a foul that occurs when a player interferes with an eligible receiver's ability to make a fair attempt to catch a forward pass. Pass interference may include tripping, pushing, pulling, or cutting in front of the receiver, covering the receiver's face, or pulling on the receiver's hands or arms. It does not include catching or batting the ball before it reaches the receiver. Once the ball touches any defensive player or eligible offensive receiver, the above rules no longer apply and the defender may tackle the receiver or attempt to prevent them from gaining control of the ball. Once a forward pass is in the air it is a loose ball and thus any eligible receiver – all defensive players are eligible receivers – may try to catch it. When a defensive player catches a forward pass it is an interception and their team gains possession of the ball. Some actions that are defined as pass interference may be overlooked if ...

Comparatively, American football has four downs, goalposts in the back of the endzone, and eleven players on each side. Canadian football is also played on a bigger field. Rugby football, from which Canadian football developed, was first recorded in Canada in the early 1860s, taken there by British immigrants, possibly in 1824.

Eligible Receiver
In gridiron football, not all players on offense are entitled to receive a forward pass: only an eligible pass receiver may legally catch a forward pass, and only an eligible receiver may advance beyond the neutral zone if a forward pass crosses into the neutral zone. If the pass is received by a non-eligible receiver, it is "illegal touching" (resulting in a penalty of five yards and loss of down). If an ineligible receiver is beyond the neutral zone when a forward pass crossing the neutral zone is thrown, a foul of " ineligible receiver downfield" (resulting in a penalty of five yards, but no loss of down) is called. Each league has slightly different rules regarding who is considered an eligible receiver. College football The NCAA rulebook defines eligible receivers for college football in Rule 7, Section 3, Article 3. The determining factors are the player's position on the field at the snap and their jersey number. Specifically, any players on offense wearing numbers betwe ...

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 legal and widespread use of the forward pass distinguishes gridiron football (American football and Canadian football) from rugby football (rugby union, union and rugby league, league) from which the gridiron code evolved, in which the play is illegal. 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 the rules. Another rule change on January 18, 1951, established that no center or guard could receive a forward pass, and a tackle may only do so if he announces his intent to the referee beforehand that he will be an eligible receiver, called a tackle-eligible play. The only Lineman (gridiron football), linemen who can receive a forward pass are the ends (tight ends and wide receivers). ...

Interception
In Ball game, ball-playing Competitive sport, competitive team sports, an interception or pick is a move by a player involving a pass of the ball—whether by foot or hand, depending on the rules of the sport—in which the ball is intended for a player of the same team but caught or otherwise brought under control by a player of the opposing team, who thereby usually gains possession of the ball for their team. It is commonly seen in football, including American football, American and Canadian football, as well as association football, rugby league, rugby union, Australian rules football and Gaelic football, as well as any sport by which a loose object is passed between players toward a goal. In basketball, this is called a Steal (basketball), steal.

Screen Pass
A screen pass is a play in gridiron football consisting of a short pass to a receiver who is protected by a screen of blockers. During a screen pass, a number of things happen concurrently in order to fool the defense into thinking a long pass is being thrown, when in fact the pass is merely a short one, just beyond the defensive linemen. Screens are usually deployed against aggressive defenses that rush the passer. Because screens invite the defense to rush the quarterback, they are designed to leave fewer defensive players behind the rushers to stop the play. Use A screen pass can be effective, but it can also be risky as it is rather easy for a defensive player, even a lineman, to interception, intercept the pass if a defender gets between the quarterback and the intended receiver—something that only happens if the offensive line misses a block, the quarterback takes too long to throw or the defense blitz (gridiron football), overwhelms the offensive line. If the pass is inte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Line Of Scrimmage
In gridiron football, a line of scrimmage is an invisible transverse line (across the width of the field) beyond which a team cannot cross until the next play has begun. Its location is based on the spot where the ball is placed after the end of the most recent play and following the assessment of any penalty yards. History The line of scrimmage first came into use in 1880. Developed by Walter Camp (who introduced many innovations that are part of the modern game of American football), it replaced a contested scrimmage that had descended from the game's rugby roots. This uncontested line of scrimmage would set into motion many more rules that led to the formation of the modern form of gridiron football (although the Canadian rules were developed independently of the American game, despite their similarities). Dimensions A line of scrimmage is parallel to the goal lines and touches one edge of the ball where it sits on the ground before the snap. In American football, ...

Professional Foul
''Professional Foul'' is a television play written by Czech-born, British playwright Tom Stoppard. It was broadcast on 21 September 1977 in BBC 2's ''Play of the Week'' series. The play is set in Prague and follows the character of Professor Anderson, a Cambridge ethics don, on a weekend visit to a philosophical colloquium. What should be a fairly uneventful trip is complicated by the intervention of the Communist government, leading to an ethical dilemma for the professor of philosophy, a situation explored by Stoppard through the opinions of several characters. The play was written to coincide with Amnesty International's "Prisoners of Conscience Year" and is dedicated to Czech playwright Václav Havel, then periodically imprisoned by the Czech Communist authorities. Stoppard has cited Havel as an influence on his writing. In the year of publication and broadcast the Charter 77 movement in Czechoslovakia presented the government with a formal protest against its violatio ...

Running Interference
In American football, blocking or interference (or running interference) involves legal movements in which one player uses his body to obstruct another player's path. The purpose of blocking is to prevent defensive players from tackling the ball carrier, or to protect a quarterback who is attempting to pass, hand off or run the ball. Offensive linemen and fullbacks tend to do the most blocking, although wide receivers are often asked to help block on running plays and halfbacks may be asked to help block on passing plays, while tight ends perform pass blocking and run blocking if they are not running routes to receive passes. Overall, blocking is a skill that virtually every football player may be required to do at some point, even defensive players in the event of a turnover. Essentially, blocking is pushing, with certain restrictions; in blocking one may not grasp another player or do any sort of pulling, and the hands must not extend beyond the line of each armpit; otherwise ...
