Yeah, this isn't really a question about Mayweather. He is following the rules. Xylocaine isn't banned in Nevada. And we have no idea how many fighters actually use it. Almost all fighters have hand problems at some point. And its not like he is doing something tricky. Mayweather's camp was open and honest about it. I don't see how Floyd should be banned from using it if its not banned. If its banned no one can use it. If its not banned then anyone can use it.
