Floyd Mayweather Jr. says he did nothing wrong in taking an IV solution to rehydrate after the weigh-in for his fight against Manny Pacquiao.

Doping officials on Thursday also backed Mayweather, saying he disclosed the infusion to them before taking it and it contained no prohibited substances.

A report Wednesday by SB Nation said representatives of the U.S. Anti-Doping Agency saw that Mayweather had taken the IV when they went to collect urine samples from him after the weigh-in. The report said Mayweather did not receive a formal exemption from the USADA for the IV until three weeks after the bout.

Mayweather fights Andre Berto on Saturday. He says he has always been a strong supporter of athletes being clean. His insistence on random testing was one reason his fight with Pacquiao took place five years after it was originally proposed.
