Floyd Mayweather Jr. reportedly was given USADA exemption to use a WADA-banned IV injection on the eve of his superfight with Manny Pacquiao.
To the UFC fan, the US Anti-Doping Agency (USADA) is here to provide a needed regulatory body to "clean up" the sport's PED problem. It sounds like a good deal at face value, but as long-time boxing journalist Thomas Hauser uncovered in an SB Nation longform, USADA is dealing with its own major credibility issues in boxing. Far and away the biggest controversy that has made the rounds on sports media is the IV use of Floyd Mayweather the night before his mega-fight with Manny Pacquiao back in May.
