Can someone explain to me how this is not a foul? Why is it still okay to hit another player so long as the ball is close to you and it's with your head (or fist if you're a keeper)? Ball is crossed, two players try to get the ball. One heads it away and the other badly headbutts the other, so badly infact that he had to go off injured. Are head injuries less serious then gettin a cut on your shin from a stud? If players can't go hard into a 50/50 challenge on the ground they shouldn't be able to go hard in the air either. We've seen cases where a player has been way later than Cahill today and nothing was done. Especially dangerous for the player, like Mason, who's not moving much but is getting hit by quite some force from someone behind him who's had a run-up.
