As far as I'm concerned, he should be missing the tournament on principle. Even if he's technically fit enough by then, he shouldn't go. He's very young, and has plenty of prospective international tournaments ahead of him. One bad tackle or collision causing a break or fracture to a leg that, yes, maybe could have done with a summer's reinforcement just to make absolutely sure, and the kid's career is over.
Hodgson's opinion counts for nothing. There's a good chance he won't be England manager after this tournament, and he knows it, so he's got no reason to worry about protecting these players' futures. He just wants a successful tournament at any cost.
