In this month's FourFourTwo, someone wrote in and said that in hockey, if a player goes down and recieves treatment from the physio, they are made to spend two minutes on the touchline. This led to a commentator remarking "They won't want the physio to come on" when one of the players took a smack of a stick on the kneecap, which I'm sure hurts more than most of the incidents that the big tarts in the Premiership roll about the floor for as they would be out of the game for two minutes. I don't know if the rule was brought in to make sure the player recieves proper medical attention or if there was a "simulation" problem in hockey, but this sounds like an excellent rule to bring in to football. After all, if a player is really injured then they should need at least a couple of minutes attention anyway. And the fourth official has bugger all else to do so he could easily be timekeeper in these situations.
