Naturally mothers care for the health of hte kid. I played football and she still worried, even tho im a big dude i cant really get hurt. It may be akward for like a month or two, but then its smooth sailing i guess?
My dad has always been supportive of anything dangerous i've ever did that he knows about... He tells me MAD stories about the shit they did overseas... To him all the American sports are watered down or "pussy" versions of their shit... they had some dangerousss ass games... let me think of some...
even a seemily pussy game like cricket is MAD dangerous.... Field hockey over there, is like rugby and ice hockey mixed together, without pads... like mofos breakin bones on the regular.

So anyways u dont really have to be worried... Can't really get hurt this day and age... and if he does... nothing that modern medicine cant fix
