Approved Ruling 1-4-7:IV
IV. As Team A is about to break its huddle, the referee notices that A35 is wearing an overbuilt facemask. RULING: A35 must leave the game for one down to get a legal facemask. Team A may use an available charged timeout in order that A35 not miss a down, but he may not play with the illegal facemask. [Cited by 1-4-7-l]
