Mayorga cant make 147 anymore, and the guy is beyond shot. He only beat Vargas because Nando was MORE shot. Mosley will stop him, then hopefully that'll be the last we ever hear of Mayorga.
Cotto wants to return soon and by the time Mayorga recovers from his soon to come KO it would take too much time. Also, that tune-up will mean nothing at all, at least a fight with Cintron is A BIT competitive to some fans considering Cotto's recent tough loss, Mayorga will offer nothing and will just be a punching bag who will fall way too soon.
