Peterson’s apparent failed drug test could squelch Mandalay Bay title bout against Khan

A failed drug test might cost Lamont Peterson the opportunity to defend his WBA and IBF junior welterweight belts against Amir Khan next week at Mandalay Bay.

According to the Voluntary Anti-Doping Association, Peterson tested positive via a carbon isotope ratio test for synthetic testosterone, jeopardizing the May 19 fight.

Peterson took a random drug test in mid-March that came back positive. The “B” sample, which was tested at the end of April, also yielding a positive result.

Peterson could not be reached for comment Monday. Barry Hunter, who trains Peterson, did not return calls seeking comment.

However, Peterson’s camp released this statement to “We have tremendous respect for VADA and its mission. Lamont, Barry and the entire team emphatically support random drug testing in the most comprehensive manner possible. We are working expeditiously with a team of pathologists and other medical specialists to confirm the origin of the test result and in full compliance with the rules of the Nevada Athletic Commission.

“Lamont has never had a positive test either before or after this isolated occurrence, and we plan to submit the medical findings by close of business Tuesday reflecting the actual facts in support of Lamont’s good faith intentions and the requirements of the commission.”

The commission on Monday was made aware of the failed test, which was administered by VADA, headed by Dr. Margaret Goodman and Dr. Flip Homansky. Both Peterson (30-1-1, 15 knockouts) and Khan (26-2, 18 KOs) agreed to the tests, as well as any random testing administered by the NAC.

VADA informed Peterson on April 13 of the first positive. VADA was told Thursday by the UCLA lab conducting the tests that the “B” sample was also positive.

When reached Monday, Goodman said: “I cannot comment on the results of tests on any of our fighters.”

Golden Boy, which is promoting the rematch of Peterson’s Dec. 10 win in Washington, D.C., learned of the situation Monday.

NAC executive director Keith Kizer withheld comment, saying he hoped to have more information today regarding the fight’s future.
