Encroachment (gridiron Football)
In gridiron football, there are several different rulings for encroachment: # In the NFL, encroachment occurs when, before the snap, a defensive player illegally crosses the line of scrimmage and makes contact with an opponent or has a clear path to the quarterback. Play is immediately stopped, just as it is with a false start (this violation would be an offside penalty in the NCAA). # In high school, encroachment includes any crossing of the neutral zone by the defense, whether contact is made or not. It is similar to offside except when it occurs, the play is not allowed to begin. Like offside violations, the violating team is penalized five yards. # In the NCAA, an encroachment penalty is called, when there is an offensive player beyond the line of scrimmage after the snapper touching the ball. There is no encroachment for defensive players in college football. The head linesman has the duty of watching out for encroachment and other similar infractions, and the line judge assis ...

False Start
In sports, a false start is a disallowed start, usually due to a movement by a participant before (or in some cases after) being signaled or otherwise permitted by the rules to start. Depending on the sport and the event, a false start can result in a penalty against the athlete's or team's field position, a warning that a subsequent false start will result in disqualification, or immediate disqualification of the athlete from further competition. False starts are common in racing sports (such as swimming, track, sprinting, and motor sports), where differences are made by fractions of a second and where anxiety to get the best start plays a role in the athletes' behavior. A race that is started without a false start is referred to as a ''fair start'' or ''clean start''. In sports Association Football (soccer) Football games cannot be restarted unless certain conditions are met. For example, both teams need to be in their own half of the field for the start of the game or res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Offside (American Football)
Offside is a minor foul in gridiron football caused when a defender crosses the line of scrimmage ahead of the snap of the ball. The penalty associated with the infraction is the advancing of the ball five yards and a replay of the down. History Definition In gridiron football, offside is a foul in which a player is on the wrong side of the line of scrimmage when the ball is snapped. This foul occurs simultaneously with the snap. Unlike offensive players, defensive players are not compelled to come to a set position before the snap. If a defender jumps across the line but gets back to his side before the snap, there is no foul. In the case of an offside foul, play is not stopped, and the foul is announced at the conclusion of the play. Media covering the games calls it a "free play" for the offense, as the non-offending team may decline the penalty and take the yardage gained on the play (and when the play works against them, like a turnover to the opposing team, the non-off ...

Head Linesman
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: Co ...
