Seriously. A guy gets concussed in a contact sport and he shakes it off and comes back to take more damage, and plays the next week, the next day.
A guy gets concussed in MMA, the fight is pretty much over and the guy doesn't take contact for months.
Excuse me? That is an extremely uneducated statement you just made. Are you familiar with a man named Sidney Crosby?
He skated for the first time since that hit two days ago, that hit was 3 months ago.
That is one of MANY examples, concussions are NO joke. Please tell me one person that has gotten a concussion and came back to play just days later, it doesn't happen.
