I have a feeling he could get "future endeavoured" soon over this tbh. Now granted, he was supposed to get thrashed by Brock at Summerslam as badly as Cena did, but this is the second major title he's going to have to drop due to that shoulder/neck injury that he refuses to have medically repaired.
WWE may not use him the way most people want but they realise how popular he is and the merchandise he moves so they'll want him to be available for anything they want him to do so if he keeps refusing to get medical help for the injury due to philosophical reasons I could see WWE releasing him since they can't force medical procedures on him but they also can't risk things like this happening or him injuring another wrestler badly if his ability to hold someone up gets compromised at the wrong time in a match.
