Mullings and Rodgers both may be out for Daegu

Two of the world's top ranked sprinters are facing doping violations that may keep them out of the World Championships in Daegu, South Korea in less than two weeks time. Jamaican Steve Mullings, ranked and American Michael Rodgers both allegedly had positive samples disclosed within the last week.
Mullings appears to have to more serious problem. He has already served a two-year suspension stemming from a 2004 violation for high levels of testosterone. Reportedly, Mullings tested positive for a masking agent at the Jamaican trials in June. He will received a hearing on August 17, but the Jamaican team must be named by the 15th, so he appears out for Daegu and now his status for London appears jeopardized.
Rodgers, who qualified for the US team in the 100 meters and 4x100 meter relay, according to his agent Tony Campbell told Reuters on Saturday he had tested positive for the stimulant last month in Italy after mistakenly consuming an energy drink that contained the unidentified banned substance. Rodgers will have his case heard by the USADA (US Anti-Doping Authority). There is more latitude for stimulant offenses as opposed to steroids or masking agents. It is possible that Rodgers could receive a warning. He has already been named to the US team, and Trell Kimmons, who placed 4th in the 100, is already on his way to Daegu as part of the relay pool.
With Usain Bolt's form in question and Asafa Powell's groin potentially problematic, the 100 meters promises to be very competitive in Daegu. Richard Thompson just ran a 9.85 at the Trinidad & Tobago nationals and Walter Dix has the best shot of the Americans.
The World Championships begin August 27.
