Besides a blogger saying it's illegal. No. It might have restrictions on fight night but as far as information anyone has come up with is. The USADA, WADA have it legal. FDA has no bans on it. NSAC you cant use it on fight night.
This content is protected LEONARD ELLERBE DENIES FLOYD MAYWEATHER'S USE OF XYLOCAINE By Tim Harrison | April 13, 2010 THE ONE THAT HYPES THE FIGHT ! :rofl THIS WILL BE JAW DROPPING FOR THE FLHOMOS :yep
I know. The USADA does not test for Xylocaine. But it is not considered illegal. We went over this already.
You yourself have said they have a Xylocaine cream. What if Ellerbe is telling the truth but they have used the cream instead and just white lied? Also, I don't remember Floyd having any hand issue in his last 3 fights. Do you?
