Las Vegas – The rematch between Lamont Peterson and Amar Kahn for the WBA and IBF junior welterweight title has been canceled. Golden Boy Promotions threw in the towel on the May 19th bout at Mandalay Bay, after Peterson tested positive for synthetic testosterone.
The Nevada Athletic Commission says Peterson tested unacceptably high for synthetic testosterone in a urine test administered in March by the Las Vegas-based Voluntary Anti-Doping Association.
The commission says separate tests on a second sample from the same time were positive May 2. Ticket holders will get a full refund.
