You do realise he said he hurt his rotatorcuff not torn it. It's a big big big big big difference to what Floyd said and what Manny said.
The surgeons report said full tear. That said I don't know the impact on the fight, was he confused or hurt? He maybe the toughest man in the world, doesn't matter though, because he's dumb as bricks for not disclosing it to the nsac.
