Out of bounds at snap
“Out of bounds” is used in American football to describe situations where a player, the football, or any portion of a player’s body is outside the playing area. Play stops, and the ball is usually placed at the point where a player or the ball went out of bounds in American football.
The “snap” occurs when the center (the man who raises the ball) sends the football to the quarterback or another offensive team member to begin a play. Action on the field begins with the snap, and players immediately begin moving and acting following the play ordered by the coach.
When you say something like “out of bounds at the snap,” you can mean that a player is out of bounds at the same instant the ball is snapped. A player is out of bounds if their foot or any part of their body is contacting or beyond the boundary line at the time of the snap. A pass may be ruled complete or incomplete, a player may be ruled ineligible to catch a ball, or a runner may be forced to halt because they have gone out of bounds, all of which might affect the outcome of the play. The rules and punishments may change depending on the play and the game’s laws.
