According to the report, USADA, which had been contracted by Mayweather and Pacquiao to conduct random drug testing for their bout, sent collection agents to Mayweather's house in Las Vegas the night before the fight to conduct an unannounced drug test.
SB Nation's account said Mayweather's medical team told the collection agents that the IV - which reportedly included a 250-milliliter mixture of saline and multivitamins and a 500-milliliter mixture of saline and Vitamin C - was being given to Floyd Mayweather for rehydration purposes following the weigh-in.
While Mayweather was given an exemption three weeks after the fight, Manny Pacquiao was denied a request to be injected with the legal painkiller Toradol on fight night to ease pain in his injured rotator cuff, which he had surgery on after the bout.
