Shoulder and it will require a pretty rough surgery. The type that could sideline him for 6-8 months from what I've heard. He may play TE, OT, or DT for us.
It just depends on how he comes back from surgery. He didn't play defense this year because of the shoulder so it's hard to tell if he has what a DT needs.
He would definitely need to take a redshirt year to gain weight if he is to play DE, DT, or OT. He has great hands so i'd like to see him at TE but I don't know if he has the speed.
