A red blotch on the back of Pac's right shoulder during the bout, also around 2-3 Mayweather definitely bent Pac's right arm in the clinch deliberately, if he knew it was injured or not is another story.
Doesn't matter. Manny's team shouldn't have let him fight in the first place.
I have no issue with Floyd exploiting it. Manny's handlers should have known better if Manny was indeed injured.
This whole thing is leaving a bad taste in my mouth....
