After failing the drug test conducted prior to his UFC 183 fight against Nick Diaz, Anderson Silva once again tested positive for steroids in the second screening after the match.

MMA Weekly said that the Nevada State Athletic Commission (NSAC) confirmed that Silva failed the second drug test with steroids detected in his body and also anti-anxiety medications.

It noted that the test discovered Drostanolone which was one of the anabolic steroid metabolites he tested positive for earlier. Aside from the illegal substance, Silva also tested for anti-anxiety drugs Oxazepam and Temazepam which are medications for those who lack sleep.

According to MMA Weekly, these drugs for the sleep-deprived are not banned in the UFC but should be indicated in the medical questionnaire submitted before the match.

The same report added that testing positive for Drostanolone the second time is a bit surprising as he tested negative for banned substances last Jan. 19.

To explain the situation, NSAC executive director Bob Bennett said that The Spider may have used the said steroid after the two tests but close to his Jan. 31 fight with Diaz.

"I can't speak for the [NSAC] Chairman nor can I speak for the commissioners. But something I find particularly concerning is that [Silva] tested positive on Jan. 9 and then he tested negative on Jan. 19. If he took this orally, it only stays in your system 5-to-7 days," Bennett was quoted by MMA Weekly as saying.

Silva earlier denied using illegal drugs and he has maintained that he never used them ever in her life. "I have not taken any performance enhancing drugs. My stance on drugs is, and will always be, the same. I'm an advocate for a clean sport," he was quoted by CBS Sports as saying.

An update by Fox Sports noted that Silva has been temporarily suspended by the NSAC on Tuesday along with Diaz and Hector Lombard who also tested positive for illegal drugs.

The UFC fighters will be under temporary suspension until a disciplinary hearing is conducted on the issue with the dates still being ironed out by the legal counsels of the parties involved.

The commission, according to Fox Sports, will again convene either in March or April and will give all the suspended fighters the chance to defend themselves and present their arguments.

Aside from the suspensions on the three athletes, UFC bantamweight Ashlee Evans-Smith also attended a disciplinary hearing after she tested positive for a banned diuretic.

Fox Sports said the NSAC "voted unanimously" to give Evans-Smith a nine-month suspension and a fine of $2,400.

These recent drug issues in the UFC should warn other fighters to be very careful if they ever plan to take medications that are not allowed by the NSAC as they will surely suffer the consequences.
