What is the proper way to apply advantage as an Assistant Referee? Or is advantage generally to be applied only by the Center?
Do I signal the foul and allow the center to determine advantage? Or may I, as the AR, keep my flag, run with the play to see what develops, and if no advantage materializes in 2-3 seconds then raise my flag and call the previous foul?
USSF answer (June 18, 2009):
In general, the AR should flag only for fouls or misconduct that the referee cannot see. However, that does not give the AR the right or privilege or power to invoke the advantage clause; that is reserved for the referee. In addition, a late flag by the AR for a foul in which the AR him- or herself might have “invoked” the advantage earlier is problematic. In the unlikely case that it might need to be done, this is a matter to be discussed in the pregame conference.
