The Nevada Athletic Commission is about to have another UFC marijuana case on its hands.

The UFC announced Friday that Diego Brandao tested positive for a marijuana metabolite at UFC 195 earlier this month in Las Vegas. The positive sample came from an in-competition test, which means Brandao faces a penalty. Marijuana is not prohibited under the World Anti-Doping Agency (WADA) code out of competition. In-competition is defined as the 12 hours before and after a fight.

The UFC referred to it as a "potential violation" of the promotion's anti-doping program, because Brandao has not yet had due process.

USADA notified the UFC of the possible violation, according to the statement. USADA will handle the results management and adjudication process with regards to Brandao's UFC future. Brandao will also have to go before the Nevada Athletic Commission (NAC), since it was an in-competition test stemming from an event in Las Vegas.

According to the UFC, USADA will work to ensure that "the Commission has the necessary information to determine its proper judgment of Brandao's potential anti-doping violation."

The statement said that the substance in question was Carboxy-THC and it was above WADA's limit of 180 ng/ml. The NAC limit is 150 ng/ml.

Brandao (20-11), a Brazil native, lost to Brian Ortega via third-round submission at UFC 195 on Jan. 2 in Las Vegas. The former winner of The Ultimate Fighter won two in a row before that. Brandao, 28, has a 6-4 record in the UFC.

Nick Diaz tested positive for marijuana for a third time in January 2015 and was handed a five-year suspension and $165,000 fine by the NAC. This week, that penalty was reduced after a settlement deal to 18 months and a $100,000 fine.
