Mayweather took WADA-banned intravenous injection before fighting Pacquiao

Undefeated American boxer Floyd Mayweather took an intravenous or IV injection of saline and multi-vitamins on the eve of his megafight with Filipino boxing star Manny Pacquiao last May 2 in Las Vegas, according to a report by SB Nation on Wednesday. According to report, the substances contained in the IV injection were not banned by the World Anti-Doping Agency (WADA) but the procedure is banned under the WADA guidelines.

The agents of the United States Anti-Doping Agency (USADA) reportedly found evidence that Mayweather used an intravenous a day before the fight, on fight day, and after the weigh-ins.

The Nevada State Athletic Association Commission has claimed the commission was not notified of the procedure.

Mayweather and Pacquiao contracted the USADA to conduct drug testing for their record-breaking fight.

The report said WADA rules do not allow intravenous infusions or injections of more than 50 milliliters per six hours “except for those legitimately received in the course of hospital admissions, surgical procedures, or clinical investigations.”

Mayweather is set to fight Andre Berto on Saturday (Sunday Manila) at the MGM Grand in Las Vegas.
