A  report by SB Nation on Wednesday that the pound-for-pound king Floyd Mayweather Jr.  took an intravenous or IV infusion of saline and multi-vitamins on the eve of his mega-fight with Filipino boxing star Manny Pacquiao last May 2 in Las Vegas.

As per report, the substances contained in the IV infusion were not banned by the World Anti-Doping Agency (WADA) however the methodology is banned under the WADA rules.

The agents of the United States Anti-Doping Agency (USADA) allegedly discovered confirmation that Mayweather utilized an intravenous a day prior to the fight, on fight day, and after the weigh-ins.

The Nevada State Athletic Association Commission has claimed the commission was not told and not notified of the procedures.

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.”

In the SB Nation report, nutrition expert Victor Conte was quoted as saying that there is something suspicious about Mayweather getting the IV treatment.

“I can tell you that IV drugs clear an athlete’s system more quickly than drugs that are administered by subcutaneous injection. So why did USADA make this decision? Why did they grant something that’s prohibited?”

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

Meanwhile, the NSAC denied Pacquiao’s request to be injected with Toradol on fight night. The drug, deemed legal under WADA standards, was supposed to ease the inflammation caused by Pacquiao’s torn rotator cuff.

Mayweather edged Pacquiao via unanimous decision on May 2 that raked in record revenues that made it the richest fight in boxing history.

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