Could Floyd's hands cost him?

We know he hurt it in the Guerrero fight. His publicist has been on record as saying he was just dealing with soreness. That night that hand was badly swollen but I've dealt with my hand looking the exact same way and was punching within a month or so. Ofcourse I was only 18 at the time and the recovery powers when young are quite remarkable. Still if Floyd's publicist says the hand was ok then it either is or he didn't want to miss his next Showtime PPV date. But given Floyd's history of hand problems and the quick turnaround one has to wonder what happens if Floyd injures the hand again in this fight. Hand injuries, especially chronic ones, have a tendency to linger. Mayweather Sr says Floyd can beat Canelo with one hand but it is such an interesting comment cuz he could actually be faced with the prospect of having to do so! He completely dominated Guerrero with one hand late but as many have said, "Canelo ain't no Guerrero"! Floyd is smart so you have to imagine he is prepared for this possibility or to prevent further injury. Canelo's ring IQ is fairly high as well and he could very well be able to pick on if Floyd's hand gets hurt. If Floyd does hurt one of his hands in the early or midrounds, do you think that could be the difference in victory or loss against Canelo?
