Steroid and other performance-enhancing drug tests given to Juan Manuel Marquez and Manny Pacquiao were declared negative Friday by the Nevada State Athletic Commission.
Marquez, 39, became noticeably more muscular before avenging two close losses by decisions and a draw by knocking out Pacquiao in the sixth round of their Saturday welterweight fight at MGM Grand in Las Vegas.
In a Monday telephone conversation with The Times, Marquez expressed full confidence that his drug tests would be negative.
Years ago, Pacquiao had been accused of using so-called “power pellets” by rival fighter Floyd Mayweather Jr. – an accusation that led to a lawsuit and financial settlement. Marquez became the center of speculation before this bout because he used former steroid figure Angel “Memo” Heredia as his strength coach.
Additionally, Nevada did not subject either fighter to any random drug tests during their two-to-four month training camps.
Marquez, angered by the implications, said he is willing before his next fight to participate in random, Olympic-style drug testing with his opponent throughout training camp.
