Could I give some one brain damage from a knock out?

Therw is this kid he is a freshman that realy is annoying and can't leave me alone and I was thinking about punching him in the face when we pass through the hall well I do know that he got a concussion through sports two to be exact and I was wondering could I give him brain damage. I dont want to kill the kid I just want to teach him a leason. And I was wonderin also thinking about consequences If its to much I it wouldn't be worth it and I play for the schools hockey team, would I get kicked off?? Thx P.S. hes my brother
you hit some one hard enough in the wrong place.... yes you can
