Yes Floyd was hurt in that round. The first right hand shook him a bit and his legs dropped a little, but it didn't effect his equilibrium like that second one. That second right hand was sort of on the side of the head, temple shot. That had his equilibrium off and his legs were shaky. The interesting thing about this was not the punch that Shane landed but how even in that state Floyd didn't let up on Mosley...! It was strange, it was as if he didn't want to give Shane any "confidence" or give Shane the momentum. He still went after him throwing hooks and straight rights, walking him down. He did this right after being rocked. It was like he didn't care. It was amazing. No guy on this forum can doubt his toughness now. Not many fighters would've did that, they would've tied up mosley or ran away. With that said, Shane WAS amped and looked good in there, just mayweather made adjustments, Shane switched into Befuddled mode looking for big shots and just not throwing shots which had more to do with what Mayweather was doing with his combos that were hard, fast, and so accurate that snapped Mosley's had across the ring. Chop Chop had Mayweather hurt more in the 4th than Shane did in the 2nd. In the 4th with Chop Chop Floyd would've went down if it weren't for the ropes... he actually had to stay on the ropes for a while until he recovered, with Shane he recovered so quickly, he was walking forward even though he still had some of his equilibrium off. But his fight with Chop Chop was his first at 140 from 135, with shane his body was more matured and stronger so shanes was more impression.
