Are you ******* kidding me
You twist your ankle badly, torn ACLs etc. Relatively rare and given a player has fallen down holding his face, the odds he gets up and is fine are 99.7%. In hockey if a guy goes down holding his face he is going to the hospital.
Basketball: elbows to the face all the time
Hockey: pucks to face, loss of teeth, broken feet from puck going 100mph, concussions, fighting, etc etc.
Soccer: sometimes they play in shirts and shorts when it's cold out
LOL
