You won't be saying that after I kick you in the nuts...
It is true though.
No matter which country you watch.
Rubgy and American Football players bash each others heads in and keep playing cause "tis but a scratch".
Football players instantly drop to the floor and roll across the whole pitch just because another guy looked at them funny.
I have played Football for many years, I often was often fouled (However you say it). Never had a single injury, and it never hurt incredibly much.
If someone tears a muscle or whatever then fair enough, but everytime someone else touches them they scream as if their leg was torn off.
