Three people familiar with the case told the AP that Gay had multiple positives this year. One of those people said one positive came at nationals and the U.S. Anti-Doping Agency has notified him of that result.
The people did not want their names used because the doping case against Gay is ongoing and the details have not been made public.
Gay’s representatives did not immediately respond to attempts by the AP to reach them.
The sprinter has already surrendered his spot at next month’s world championships. 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 May 16 positive. The May 16 test has been confirmed by a test of the “B” sample, one of the people familiar with the case said.
A first-time offense for doping usually brings with it a two-year ban, though athletes who cooperate with USADA sometimes get reduced penalties.
