When is a substitute considered an actual player in the game?

A substitute is considered an actual player in the game when they are legally on their side of the neutral zone. This means that the substitute must enter the field at the appropriate time, following the rules that govern substitutions. Simply being on the sideline or entering the field doesn't grant them player status; they must ensure they are positioned correctly to be part of the active play.

By being on their side of the neutral zone, the substitute is in a position where they can legally participate in the game, contributing to the team’s strategy and execution of plays. The neutral zone serves as a barrier between the offense and defense, and being on the proper side ensures the integrity of the game by adhering to the regulations that prevent immediate engagement with opponents.

Movement past this point prior to the snap could result in penalties, but once they legally occupy the correct position, they are considered an active player, ready to engage in the game action.
