"The ball is in the referees' court. The instructions are now clear on this matter: if a player is lying on the floor, the opposing team are not required to put the ball into touch. ... The referee
should only intervene if he believes a serious injury has occurred. When a 'stricken' player seeks to return to the field of play immediately after being taken off, the referee can make the player
wait until the numerical disadvantage has had an effect on the game."
-- FIFA President Sepp Blatter
believes too many players fake injuries and wants refs to punish them
by delaying their return to the field. (Reuters
