Ultimately it would be on the physical examination.
All I can say is that it is well documented that Kanter had a back injury during the Hoop Summit.
I'm not a doctor, and so this would ultimately be down to the doctors examining him AND the Jazz's assessment of risk.
im not sure but as far as i know it wasnt a back injury in nike hoop summit, he was flu or smthng like that and he got a few injections to be able to play in the game.
he doesnt have that much disastorous injury past. Just there are some concerns about his knee but nothing is for sure, its just a concern. I dont think it will be as bad as Oden, or he will even miss 1 yr like Griffin. As long as he is fine in the phsycal tests, there will be no problem for any team to pick him.
