I read from a Norwegian site something that amused me; if only the captain is allowed to discuss with the ref and the ref only talks directly to the captain, how on earth is everyone on the team, back to front, supposed to be able to know that whoever trips a player the next time will receive a yellow, no matter. As far as I know, there are no timeouts in football for the captain to inform the players, nor is it the American huddle up sequence before a play either. It just goes to prove how completely in the wrong Oliver was with that stupid decision.
