Watch Corley vs Mayweather Jr. Corley rocks PBF and makes his knees buckle. Lucky for Floyd that he was not in the center of the ring as the shots sent Floyd back and onto the ropes where he survived and Chop-Chop is not a great finisher. Corley had Floyd hurt a few times. There is another fight in PBF's career where he was rocked by? I am not sure who it was, let me look.
