USADA Chief Tygart says Xylocaine okay for Mayweather

:wtf: Los Angeles - Manny Pacquiao has removed one of the major negotiating barriers in achieving a bout against Floyd Mayweather Junior by agreeing to blood testing up to fourteen days before a bout. As the boxing community awaits Mayweather's response, The Boxing Truth Radio invited the Chief Executive Officer of the United States Anti-Doping Agency (USADA) Travis Tygart to share some of the ins and outs regarding their more stringent style of drug testing. Tygart, whose organization would be in charge of the drug testing for a possible Mayweather - Pacquiao bout, made it clear that a drug test for a bout in the Fall of 2010 would not shed any light on the possible use of performance enhancing drugs prior to the six month testing windows for the event. Theoretically, Pacquiao and Mayweather could have used drugs up to six months before there future battle and nobody would be able to verify that use. Though it would be harder for Mayweather, who was tested by the USADA before his bout with Shane Mosley earlier this month. There has been some discussion of Mayweather possibly using a numbing agent called Xylocaine to numb his historically brittle hands in the weeks leading up to fights in recent years. Though nobody in Mayweather's camp has admitted to the use of this drug, an HBO Boxing pre-fight segment back in 2002 hinted to Floyd possibly using the substance. Regardless of Mayweather's use of Xylocaine, or non-use, the drug is legal and not on the banned substances list as confirmed by Tygart on The Boxing Truth Radio. It was also reviled by Tygart that the subject of Xylocaine use had come up in the negotiations for drug-testing used before and after Mayweather's bout with Shane Mosley.
