Swimmer Jessica Hardy withdrew from the US Olympic team yesterday, four weeks after testing positive for a banned substance at the national trials.
The US Anti-Doping Agency announced Hardy's decision, saying she did so "in the best interests of the team."
The 21-year-old from Long Beach, Calif., could have contested the results before the American Arbitration Association and potentially filed an appeal with the Court of Arbitration for Sport.
Hardy tested positive for a low level of clenbuterol, a prohibited anabolic agent, at the trials July 4.
Hardy did not contest the laboratory findings and was granted additional time by the arbitration panel to investigate possible causes of her positive test.
Hardy was tested three times at the trials in Omaha. The results were negative for the samples taken July 1, after she won the 100-meter breaststroke, and July 6, when she finished second to Dara Torres in the 50 freestyle.
McNeill given warningTim McNeill received a warning for getting a prescribed anti-inflammatory shot without the proper clearance from anti-doping authorities, the second gymnast in a month to be punished for that.
The USADA said McNeill tested positive May 24 at the US gymnastics championships for a glucocorticosteroid, a cortisone-like drug that is allowed only during competitions with an exemption. Olympian Morgan Hamm had a positive test for the same anti-inflammatory that day, and also drew a warning from the USADA.
