Offside vs. Encroachment — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on May 13, 2024
Offside is a position violation in sports, notably in soccer, where a player is too far forward at the time of the ball's play; encroachment refers to an illegal movement into the restricted area, often seen in American football before the snap.

Key Differences
Offside in soccer occurs when a player is positioned closer to the opponent's goal line than both the ball and the second last opponent at the moment the ball is played to them. In contrast, encroachment in American football happens when a defensive player crosses the line of scrimmage and makes contact with an opponent before the ball is snapped.
The offside rule is crucial for maintaining fair play and preventing players from gaining an unfair advantage by waiting near the opponent’s goal. On the other hand, encroachment is strictly regulated to ensure fair and safe initiation of play in football.
Penalties for offside in soccer result in a free kick for the opposing team from where the infringement occurred. Whereas, encroachment in American football typically results in a penalty of five yards against the offending team.
The offside rule does not apply at all times in soccer; it is only in effect when the ball is being played forward. In contrast, encroachment can occur any time before the snap in American football, making its timing and the players’ positions strictly scrutinized from the line of scrimmage.
Detection of offside in soccer often requires the assistance of linesmen who monitor the movement of players in relation to the ball and each other. Encroachment, however, is usually spotted by referees who observe defensive movements across the line of scrimmage.

In soccer, the offside rule has evolved significantly, with changes to how and when a player is considered to be interfering with play. In American football, encroachment rules have remained fairly consistent, emphasizing the importance of discipline in line formation and start of play.
