Will floyds hand pain killers show up on the additional steroid (paranoid) tests?

Mayweather has been known to use hand-injected painkillers like Xylocaine, which is illegal in some states. Everyone knows Floyd uses xylocaine to numb his hands, the advantage is his, he can throw punches without feeling a thing. Manny DOESNT use xylocaine. If Floyd injects xylocaine, it will only be the day of the fight. The question is, IF they test after the fight and Floyd tests positive for this, what are the consequences? Since these tests are from his own being, what are the penalties? The NASC wont do anything since it is legal in Nevada, but they could be illegal in an olympic style test. Floyd brought this upon himself. If he still does this I have a feeling he will get popped, unless they note this in the contract. Roach And Co should definitely make this illegal in the fight if floyd insists Manny is on roids. We already know Floyd cheated on the scales, AND he's taken substances banned in other states to gain the upperhand. http://www.insideboxing.com/Columnist/frank_gonzalez/sharkies_machine_april_21.htm On another note... Roger Clemens says he was injected with "lidocaine (Xylocaine) and B-12" and not steroids or human growth hormone by former trainer Brian McNamee, http://sports.espn.go.com/mlb/news/story?id=3179745
