If I were a defensive lineman, I'd be pretty embarrassed if I had to miss a season because of an injured thumb... I'd be shocked if he isn't ready by fall
Edit: I realize it's probably extremely painful and will take time to recover, and he may never get the full use of his thumb back. It's his right thumb, so he might not be able to throw for track & field either. I do know he's a tough dude and he'll work his butt off to get back to full speed.
@teachercdI think he missed a full season but he was eventually back. JPP, wish he would have come to Nebraska, but yes, that moron blew off his fingers.
Davis probably broke a couple bones in his thumb, and hand/finger injuries require surgery. This probably won't limit him much, and he should be ready for the Fall.
