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 the defender is attempting to catch or bat the ball rather than focusing on the receiver.[ citation needed ]
The intended receiver may find themselves a defender if a defensive player has a better chance to catch a forward pass. If an offensive player commits pass interference against a defensive player attempting to intercept a forward pass it is offensive pass interference.[ citation needed ]
Rules for pass interference differ between American and Canadian football:
In the NFL, the defender may make continuous contact with the receiver within the first five yards of the line of scrimmage. Anything after that is penalized as illegal contact. Pass interference is called if the defensive player contacts the offensive player while he is trying to catch the pass, unless the defender has turned his head to face the oncoming pass and is attempting to intercept it. Accidental, glancing contact is not penalized.[ citation needed ]
In high school and college, the defender may make contact with the receiver as long as the receiver is in front of the defender. These provisions end when the pass is in the air.[ citation needed ]
In the NFL, when a team presents a punt formation and before the ball is kicked, acts that normally constitute pass interference against the end man on the line of scrimmage or against an eligible receiver behind the line of scrimmage, who is aligned or in motion more than one yard outside the end man on the line, are not considered pass interference. [2]
In the NFL and the Canadian Football League (CFL) the penalty for defensive pass interference is an automatic first down at the spot of the foul. If the foul occurs in the end zone, the ball is placed at the one-yard line (or half the distance to the goal if the line of scrimmage was inside the two-yard line). In U.S. college football and amateur Canadian football, the penalty is an automatic first down at the spot of the foul, up to a maximum of 15 yards from the previous spot. In U.S. high school rules the penalty for both offensive and defensive pass interference is 15 yards from the previous spot with the down replayed. Prior to 2013, the penalty for defensive pass interference also included an automatic first down while the penalty for offensive pass interference included a loss of down. In the NFL and CFL, the penalty for an offensive pass interference is 10 yards from the previous spot. In amateur Canadian football, the penalty is 15 yards.[ citation needed ]
In certain situations a defensive player deliberately commits pass interference against an intended receiver who would surely make a huge gain or score a touchdown were he to catch the ball. This is especially true in NCAA and amateur Canadian football, where the penalty for pass interference that occurs more than 15 yards upfield is less severe than under professional rules. In U.S. high school, if the covering official deems the interference intentional rather than incidental, 15 additional yards may be assessed (although this is seldom called). [3]

Canadian football, or simply football, is a sport in Canada in which two teams of 12 players each compete on a field 110 yards (101 m) long and 65 yards (59 m) wide, attempting to advance a pointed oval-shaped ball into the opposing team's end zone.
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". 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" is called. Each league has slightly different rules regarding who is considered an eligible receiver.
A wide receiver (WR), also referred to as a wideout, and historically known as a split end (SE) or flanker (FL), is an eligible receiver in gridiron football. A key skill position of the offense, WR gets its name from the player being split out "wide", farthest away from the rest of the offensive formation.
Gridiron football, also known as North American football, or in North America as simply football, is a family of football team sports primarily played in the United States and Canada. American football, which uses 11 players, is the form played in the United States and the best known form of gridiron football worldwide, while Canadian football, which uses 12 players, predominates in Canada. Other derivative varieties include arena football, flag football and amateur games such as touch and street football. Football is played at professional, collegiate, high school, semi-professional, and amateur levels.
American and Canadian football are gridiron codes of football that are very similar; both have their origins partly in rugby football, but some key differences exist between the two codes.
Strategy plays a crucial role in American football. Both teams carefully plan various aspects of their gameplay in an effort to win. This includes deciding on formations, selecting players for specific positions, and assigning roles and instructions to each player on offense and defense.
Gameplay in American football consists of a series of downs, individual plays of short duration, outside of which the ball is or is not in play. These can be plays from scrimmage – passes, runs, punts or field goal attempts – or free kicks such as kickoffs and fair catch kicks. Substitutions can be made between downs, which allows for a great deal of specialization as coaches choose the players best suited for each particular situation. During a play, each team should have no more than 11 players on the field, and each of them has specific tasks assigned for that specific play.
In gridiron football, an official is a person who has responsibility in enforcing the rules and maintaining the order of the game.
An incomplete pass is a term in gridiron football which means that a legal forward pass is not successfully caught by an eligible offensive player within the field of play. An incomplete pass can occur if (1) the ball hits the ground in the field of play before a player on either team gains possession; (2) the ball is caught by a player on either team who, at the moment of possession is out of bounds; or (3) the ball is thrown outside the field of play. An incomplete pass causes the down to advance by one and the offensive team gains no yards. The game clock is stopped.
A formation in American football refers to the position players line up in before the start of a down. There are both offensive and defensive formations and many in both categories. Sometimes, formations are referred to as packages.
In football, the tackle-eligible play is a forward-pass play in which coaches will attempt to create mismatches against a defense by inserting an offensive tackle, into an offensive formation as an eligible receiver, usually as a tight end or as a fullback. This is done by changing the formation of the offensive line, via positioning two linemen on one side of the center and three linemen on the other.
A trick play, also known as a gadget play, gimmick play or trickeration, is a play in gridiron football that uses deception and unorthodox tactics to fool the opposing team. A trick play is often risky, offering the potential for a large gain or a touchdown if it is successful, but with the chance of a significant loss of yards or a turnover if not. Trick plays are rarely used not only because of the riskiness, but also to maintain the element of surprise for when they are used.
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 defense, and "special teams". Within these three separate "platoons", various positions exist depending on the jobs that the players are doing.
In gridiron football, intentional grounding is a violation of the rules where "a passer...throws a forward pass without a realistic chance of completion." This typically happens when a quarterback about to be sacked passes the ball toward an area of the field with no eligible receiver. Without this rule, the quarterback could almost always avoid a sack by intentionally throwing an incomplete pass ; instead, the penalty of intentional grounding effectively continues play as if the defense had succeeded in sacking the quarterback.
An official in Canadian football is a person who has responsibility in enforcing the rules and maintaining the order of the game, like their counterparts in the American game. In the Canadian Football League, seven officials operate on the field. Lower levels of play up to the university level use less than the standard seven.
In gridiron football, motion refers to the movement of an offensive player at the time of the snap.
The following terms are used in American football, both conventional and indoor. Some of these terms are also in use in Canadian football; for a list of terms unique to that code, see Glossary of Canadian football.
In gridiron football, a penalty is a sanction assessed against a team for a violation of the rules, called a foul. Officials initially signal penalties by tossing a bright yellow colored penalty flag onto the field toward or at the spot of a foul.
In gridiron football, a punt is a kick performed by dropping the ball from the hands and then kicking the ball before it hits the ground. The most common use of this tactic is to punt the ball downfield to the opposing team, usually on the final down, with the hope of giving the receiving team a field position that is more advantageous to the kicking team when possession changes. The result of a typical punt, barring any penalties or extraordinary circumstances, is a first down for the receiving team. A punt is not to be confused with a drop kick, a kick after the ball hits the ground, now rare in both American and Canadian football.
