Any new blood in the heavyweight division (or in his case, reborn) is welcome by me. He has an exciting style and I think could give some of them decent fights.

I am not sure how severe his brain injury was, but he spoke so well last night you would never knew he suffered one. Even severe concussions cause some brain damage and quite often small brain bleeds and bruising.

I think if he is at the point where medical experts say it is as safe for him to fight as anyone else, let him go for it and lets see what he can do.
