Promoters seek clarity over Peterson tests

Amir Khan’s world light-welterweight title rematch against Lamont Peterson on May 19 is in doubt after the show’s promoter Richard Schaefer claimed the American has failed a drugs test.

Schaefer said he was informed by the Nevada State Athletic Commission that Peterson had shown abnormally high levels of a banned steroid in a urine sample submitted in March to the Las Vegas-based Voluntary Anti-Doping Agency (VADA).
