Collazo would set Hatton back. He's in a situation right now where he's under the hammer. He will be stripped of his belt if he doesn't fight Urkal. Mandatories never bothered Hatton before because he had better things to do, and right now no other fight is forthcoming. And to be perfectly honest nobody is going to risk a belt or their reputation against Hatton because if they were to take that fight and win, they wouldn't get a title anyway. Hatton will be stripped as soon as he takes any fight against anyone but Urkal.
