I'm sorry to hear that. Strip him. If he's mentally unfit to fight then he's not mentally fit to be the champ.
I think so, too. Whatever is ailing Fury, even if its "just" some depression or fear of failure, it must be real and serious in his mind. He is letting go of his titles and the biggest payday of his career thus far. Peter Fury said before that the rematch contract stipulates Team Fury getting the majority of the purse, i.e. > 50%. That would easily be more than 10 million pounds I guess.
