Yes - he is not in any immediate danger of dying with a broken leg. Yes it might hurt like hell, but tell me if it needed fixing there and then. Would you have personally operated right then or would he have waited until the next day?

One way to stop the cheating will be that if the ref has to stop the game and the player then gets up he goes off the pitch as if he had been treated by the pyhsio!
