In an expected move, the Nevada State Athletic Commission today issued temporary suspensions to Anderson Silva, Nick Diaz and Hector Lombard in the wake of their recent failed drug tests.

Additionally, Ashlee Evans-Smith was suspended and fined following a drug-testing failure of her own.

The NSAC handed out the suspensions during today’s regular monthly meeting in Las Vegas.

For fighters who fail drug tests, the NSAC traditionally hands out temporary suspensions pending a more formal hearing at a subsequent meeting. The date for the commission’s next meeting hasn’t been set, but Nevada Deputy Attorney General Chris Eccles assured the fighters and their reps that they’ve be given proper time to prepare.

Former UFC middleweight champion Silva (34-6 MMA, 17-2 UFC) earned a decision victory over ex-Strikeforce welterweight titleholder Diaz (26-10 MMA, 7-7 UFC) in UFC 182’s pay-per-view event on Jan. 31. However, both fighters failed drug tests. Following the Las Vegas event, the NSAC announced Silva failed an out-of-competition drug test due to drostanolone metabolites, which indicate the use of an anabolic steroid, as well as androsterone, a form of endogenous testosterone.

Additionally, just prior to today’s meeting, the NSAC released its complaint against Silva. In addition to the out-of-competition, a pre-fight test showed drostanolone metabolites once again. Meanwhile, the post-fight test was positive for oxazepam and temazepam. Those medications are used to treat anxiety and insomnia, respectively.

Silva’s co-manager, Michael Alonzo, called in and represented him during the meeting.

Diaz, meanwhile, failed a post-fight drug test due to marijuana metabolites, his third such offense in Nevada during his pro career. His manager, Lloyd Pearson, represented Diaz during the meeting.

Lombard failed a UFC 182 drug test due to desoxymethyltestosterone, a designer steroid. Lombard (35-4-1 MMA, 4-2 UFC) defeated fellow welterweight Josh Burkman (27-11 MMA, 5-6 UFC) at the Jan. 3 event. Craig Zimmerman today represented Lombard.

Evans-Smith, meanwhile, tested positive for a diuretic following UFC 181. Evans-Smith (3-1 MMA, 0-1 UFC), a late replacement on the card, suffered a submission loss to fellow bantamweight Raquel Pennington (5-4 MMA, 2-1 UFC) at the Dec. 6 event. Neither Evans-Smith nor a representative called into the meeting, though Eccles said they were notified and planned to.

Evans-Smith pointed to a possible tainted supplement, but she didn’t disclose any use on her pre-fight questionnaire. The commission ultimately decided to issue a nine-month suspension and fined her 30 percent of her purse ($2,400). She’s also need to submit a clean drug test before her next fight.
