I'm not a doctor but from what I saw, he probably had a concussin which most of you have already figured out. He'll be fine.
Has anyone gone over to the Gator forums yet to see if there is blood on the screen from all the slit wrist??? Thinking about going over there I got some surplus rope I could proably get rid of really quick...its great for nooses.
NOT only that but even if he does play if you come back to quick its like 75% more likely you will get another one if hit.
