As expected, Anderson Silva, Nick Diaz and Hector Lombard were issued temporary suspensions by the Nevada Athletic Commission on Tuesday.

All three fighters will be required to attend a future disciplinary hearing, where fines and long-term suspensions will likely be issued. The date of that hearing will be determined in the coming days, according to NAC Chairman Francisco Aguilar.

Silva defeated Diaz via unanimous decision in the UFC 183 headliner at MGM Grand Garden Arena in Las Vegas on Jan. 31. In addition to a fine and suspension, Silva’s victory could also be overturned to a no contest at the upcoming hearing.

Silva tested positive for two different anabolic steroids -- drostanolone metabolites and androsterone -- during a pre-fight drug test administered ahead of his bout with Diaz on Jan. 9. The former middleweight champion also tested positive for Oxazepam and Temazepam in a post-fight urine test administered on Jan. 31. Oxazepam is used to relieve anxiety, while Temazepam is an anti-insomnia medication. In addition, “The Spider” again tested positive from drostanolone metabolites . The NAC revealed the results of the second failed test on Tuesday.

Diaz, meanwhile, tested positive for marijuana in a post-fight drug test following the UFC 183 main event. The Stockton, Calif., resident’s urine sample had 300 nanograms per milliliter of marijuana metabolites, which is double the NAC’s allowable limit of 150 ng/mL.

Diaz also tested positive for marijuana following a win over Takanori Gomi at Pride Fighting Championships 33 on Feb. 24, 2007; the NAC overturned that victory to a no contest. Diaz was suspended for six months and fined 20 percent of his purse. Nearly five years later, the former Strikeforce champion again tested positive for marijuana following a unanimous decision loss to Carlos Condit at UFC 143 on Feb. 4, 2012. Diaz was later suspended for one year and fined 30 percent of his purse from the bout.

Lombard defeated Josh Burkman via unanimous decision at UFC 182 on Jan. 3. A drug screen administered on the day of the fight revealed that the Cuban welterweight tested positive for the steroid desoxymethyltestosterone (DMT). The NAC received Lombard’s test results on Jan. 13. Like Silva, Lombard’s victory over Burkman could be ruled a no contest.

Lombard was scheduled to face Rory MacDonald at UFC 186 on April 25 but the bout was scratched when the failed test came to light.
