The unfortunate reality is that Jarvis will likely never see the court in a game as a Gopher. That only changes if something dramatic happens when he's evaluated by the U's medical staff before the season, like every player is. He played this summer in the Pro-Am and by all accounts looked good. He plays on his own, but can't do anything in official practice or workouts.
While he probably could play and can do so at a high level, the U leaders don't want to assume the risk, especially legally, if something were to happen on the court. Even if he were to sign a waiver acknowledging the risk (which would've been done by now if it was an option), it doesn't take liability away from the U.
It's unfortunate. I want to see Jarvis play as much as anybody. Kudos to him for keeping his head up and sticking with the program despite the circumstances. Great kid.
