'He should be commended for that and for removing himself from world championships, which we all should appreciate. 'The additional positive sample is consistent with him taking responsibility,' said the Usada chief executive, Travis Tygart.
The 16 May test has been confirmed by a test of the 'B'' sample, one of the people familiar with the case said.Ī first-time offense for doping usually brings a two-year ban, though athletes who cooperate with Usada sometimes get reduced penalties. If a positive test from nationals is confirmed by his 'B'' sample, those results would be vacated, though it's likely they would be anyway because of his 16 May positive. The sprinter has already surrendered his spot at next month's world championships.
