What positions did you play in football?

Football is know for unreported concussions due to the "shake it off and get back into the game" attitude. Different positions have different rates of expected impacts.

Basketball is know for head impacts as players try to move past one another or jump up under another's head or chin. Add in the occassional header to the floor and it can be a risky sport for a previously concussed brain. It is considered a contact sport from an injury stand point.
