American Football IFAF Approved Ruling 1-4-8
I. After the ball is ready for play, an official identifies a player(s) who is obviously not wearing a mouthpiece. RULING: The player(s) must leave the game for at least one down and may not return until properly equipped with a mouthpiece. The player(s) may remain in the game by spending an available team timeout, but they may not play until properly equipped.
II. Late in the first half, Team B has used its three timeouts. At the end of a play the line judge notices that B44, a player who participated in the previous play, is equipped with an eye shield that is either tinted or not clear. RULING: Equipment violation. B44 must leave the game for at least one down and may not return if he is wearing an illegal eye shield.
III. When the ball is dead after a scrimmage down, the Umpire notices that linebacker B55 has an exposed back pad at waist level, which apparently became exposed through play during the previous down. RULING: B55 is not required to leave the game, but he must cover the exposed pad with his jersey before the next down.
