Floyd Mayweather Jr., who is training for his September 17 battle with WBC welterweight champion Victor Ortiz, once again discussed the possibility of facing Manny Pacquiao in 2012. The two camps continue to have a verbal dispute as to which side is avoiding the fight. While Pacquiao, and his promoter Bob Arum of Top Rank, state there are no issues holding back the fight, Mayweather holds his position that Pacquiao is avoiding the contracted agreement of subjecting himself to a pre-fight protocol for Olympic-style drug testing to detect performance enhancing drugs.

"You've got to ask yourself this. I don't have anything against Manny Pacquiao. But is it Manny Pacquiao or Bob Arum?" Mayweather said to the Grand Rapids Press. "It is what it is. I'm not here to say nothing negative about Bob Arum. I'm not here to say nothing negative about Manny Pacquiao. He do what he do, I do what I do. All I ask, as a gentleman, let us both take the test and let's fight.  It's obvious (Pacquiao) don't want to do it."
