Pacquiao files Mayweather lawsuit

Manny Pacquiao has filed a lawsuit against Floyd Mayweather Jr and Golden Boy Promotions boss Oscar de la Hoya over claims he has used performance-enhancing drugs.

The Filipino fighter, a six-weight world champion, withdrew from a potentially hugely lucrative bout against Mayweather in March next year after the American’s camp demanded Olympic-style drug-testing procedures be put in place in the lead-up to the fight.
