Aldo and McGregor accuse each other of PED use

The UFC 189 World Tour made a stop in Los Angeles on Tuesday, and the usual trash talk between Conor McGregor and Jose Aldo took a different turn, with each man accusing the other of using performance-enhancing drugs.

"It seems to me like maybe it's Brazilian culture - the women are on it, the men are on it; I don’t know what to think," McGregor told reporters. "I don’t have to think. (The fight) is in Vegas. We're in a new age. The sport is being cleaned."

Aldo didn't take the accusation lightly, and fired a salvo of his own, first accusing the brash Irishman of using PEDs, before suggesting they undergo a drug screening every single week until the fight on July 11.

"He’s the one that's taking substances," Aldo said through a translator. "There’s no surprise why he fights in this weight class. In his country, they don't even have a commission to put rules on it. Something that I'm going to do, I'm going to ask for doping tests to be given (to McGregor) every single week, and I’m here to be tested to prove that (I'm clean)."

The UFC has been rocked by high-profile test failures of late, including legendary middleweight Anderson Silva, who flunked multiple screenings before and after his bout with Nick Diaz at UFC 183.
