Players who may legally touch a forward pass. On the passer's team, these are: the ends, the backs, and (except in the NFL), one player in position to take a hand-to-hand snap, i.e. a T quarterback; provided the player's shirt displays a number in the ranges allowed for eligible receivers. All players of the opposing team are eligible receivers, and once the ball is touched by a player of the opposing team, all players become eligible.
