Disqualifications

I (M) play a high contact sport (Football) in a high contact/injury position (Running back). Although I have never had any injuries over the years of play this sport or any other sport, the chances of injury are even higher as I play against higher-level high school teams (5a and 6a schools). I was wondering do concussions, fractures, and dislocations disqualify you from getting accepted into a service academy?

Thanks!
