It’s less than 80%. It’s as soon as he’s able to play, either 60 or 65%. Your safest play is to just leave a freshman with promises where they are on the depth chart when they get hurt. They won’t play when they are too injured, and as soon as they are able to play, they’ll expect to be back anyway. It does sting, especially if they have low durability and go from 60 to 100 slowly. This is basically the *only* place in the game where durability matters, coming back from long injuries.
