-12- ABSTRACT A way of enhancing spectator enjoyment of football. Each referee has a holder for the flag. When an off-side, clipping, backfield in motion, etc., is observed, the referee drops the flag to signal a rules infraction. The holder senses the removal of the flag. By means of a radio link, the sensing of the flag re- moval is relayed as to a receiving station. In turn, a signal flashes on the stadium scoreboard and on the televised transmission as viewed on a television re- ceiver screen. By virtue of this arrangement, the spectators know that the play may be called back, even though the players themselves may not be aware that a flag has been dropped to signal a rules infraction and will continue to play.
