LAS VEGAS -- The Nevada State Athletic Commission voted unanimously on Tuesday to temporarily suspend the license of recently retired martial artist Chael Sonnen.
Sonnen (28-14-1) had been scheduled to fight Vitor Belfort at UFC 175 on July 5 in Las Vegas, but was pulled from the card last week when it was announced he had failed a random drug test taken in May.
Sonnen, 37, tested positive for the anti-estrogen drugs anastrozole and clomiphene. He announced his retirement from the sport the day after the results went public.
The NSAC quickly voted to suspend the license Sonnen received on May 13 to fight professionally in Nevada. A full hearing to determine the details of the disciplinary action will be set on a date to be determined.
Sonnen appeared before the commission via conference call, but was not given the opportunity to provide comment.
A three-time title contender in the UFC, Sonnen fought professionally for 17 years. In an interview on Fox Sports, he admitted taking the banned substances to avoid the side effects of getting off testosterone-replacement-therapy (TRT), which the NSAC banned in combat sports earlier this year.
