For encroachment purposes, when is a substitute considered to be a player?

A substitute is considered to be a player when he is on his side of the line of scrimmage because this is the moment when he is actively participating in the play and is subject to the same rules as players. Prior to this, while on the sidelines or before entering the game, the substitute is not considered involved in the current play.

Specifically, once the game is in progress and the substitute crosses the line of scrimmage, he can be penalized for encroachment if he disrupts the play or makes contact with an opponent during this time. Being on the team’s side of the line of scrimmage indicates he is in the field of play and able to affect the outcome, linking his status as a player to the specific context of potential infractions, such as encroachment.

Understanding this distinction is crucial for managing substitutions effectively and ensuring compliance with the rules governing player statuses during game play.
