I have never had a back problem but to be fair I mostly train boxing/kickboxing and I stopped doing judo because of getting thrown was way too rough. I assume that the nature of WWE is very rough on the body and creates great wear and tear. I am curious to know how well a back can recover after a surgery and how well does it respond to MMA training? For example, would shooting for takedown be harder for the back then say getting thrown? Also what about the kickboxing portion, If he tries to use footwork,kicks and punches, would his back slow his movements down?
