Mayweather allegedly used illegal injection

Undefeated welterweight champion Floyd Mayweather Jr. allegedly took a banned intravenous injection before his May 2 fight with Manny Pacquiao.

According to Thomas Hauser of SB Nation, Mayweather received an intravenous injection of vitamins and saline just before his mega-fight with Pacquiao in Las Vegas. 

Although the substances were not banned by the World Anti-Doping Agency, IV injections of more than 50 millilitres per six hours "except for those legitimately received in the course of hospital admissions, surgical procedures, or clinical investigations", are not allowed as per WADA

According to WADA, IV infusions can be used to "dilute or mask the presence of another substance."

Three weeks after the fight the United States Anti-Doping Agency (USADA) reportedly gave Mayweather an exemption 

But Bob Bennett, executive director of the Nevada State Athletic Commission, now says that the USADA were not authorised to give the exemption and only notified NSAC and Pacquiao’s promoter Top Rank about the incident 20 days after the bout.

It has now been reported that Mayweather’s camp only applied on May 16 for a Therapeutic Use Exemption (TUE) for the IV injection and it was granted on May 20 by the USADA.

At one stage just before the May 2 fight, the Pacquiao camp was turned down by the NSAC when they applied to use anti-inflammatory shots to the Filipino’s shoulder.

Bennett told Hauser that it was totally unacceptable that the IV injection was not done at a medical facility.

"The TUE for Mayweather's IV – and the IV was administered at Floyd's house, not in a medical facility, and wasn't brought to our attention at the time – was totally unacceptable. 

“I've made it clear to Travis Tygart that this should not happen again. We have the sole authority to grant any and all TUEs in the state of Nevada. USADA is a drug-testing agency. 

"USADA should not be granting waivers and exemptions. Not in this state. We are less than pleased that USADA acted the way it did," Bennett said.
