I don't want you to listen to anything, if you clicked the link and downloaded them you would see that they are videos of EXTREME football injuries. I do know you get a PENALTY for contact in soccer, so therefore it's not allowed, i never said it didn't happen, of course it does. I don't know why you want to compare rugby to american football, there are similarities but they are not even close to the same sport. Once again, watch this and actually watch it this time, and then come back and say football is pussy or not tough enough (No injuries in this one, just some ridiculously hard hits):
