D.C. boxer Lamont Peterson isn’t only fighting allegations that he used a banned substances, but the fallout from his positive test caused a promoter to move a June 30 fight from D.C. to California, reports ESPN:

Golden Boy Promotions CEO Richard Schaefer said Monday that he has decided against putting on a planned June 30 Showtime card in Washington, D.C., because of the continuing fallout from the disclosure that junior welterweight titlist Lamont Peterson failed a random drug test while preparing for a rematch with Amir Khan.

Instead, Schaefer told ESPN.com that he is moving the special edition of Showtime’s “ShoBox: The New Generation” to the Fantasy Springs Resort Casino in Indio, Calif.

Peterson originally defeated Khan in a championship fight in D.C. in December, but Khan’s promoter has asked the D.C. Boxing and Wrestling Commission to nullify the results of the fight. Until it does so, Khan’s promoter says he can’t trust D.C. to put on a fair fight:

“We have to move the Washington show,” Schaefer said. “We want to see what will happen in with the whole Khan-Peterson thing. The Washington, D.C. commission, the IBF and the WBA can make a statement that they don’t tolerate fighters using banned substances, using testosterone. Peterson said he took it in November, which means he had it in his system when he fought Amir.

“I need to make sure when I go somewhere to do a fight that the jurisdiction knows how to deal with world championship boxing events and that the commission in Washington is going to do the right thing before I go back there. So I am not going to go to Washington on June 30.”

Peterson has admitted to using testosterone pellets before the December fight, but said that they were for medical reasons. According to the AP, he’ll appear before Nevada boxing regulators on June 13 to make his case.
