Usman Nurmagomedov has been suspended 6 months by the California State of Athletic Commission after testing positive for a banned substance following his fight against Brent Primus at Bellator 300, per CSAC executive officer Andy Foster. That win has now been turned into a no…

The 25-year-old Nurmagomedov was tested after defeating Brent Primus via unanimous decision in San Diego on Oct. 6 to defend his belt and also win his semifinal bout in the Bellator Lightweight World Grand Prix.

Nurmagomedov was scheduled to defend the lightweight title against the winner of the Grand Prix semifinal between ex-champion Patricky Pitbull and Alexandr Shabliy. That semis bout will take place next Friday in Chicago.

However, MMA journalist Cole Shelton reported that Nurmagomedov has been removed from the Grand Prix. That opens the door for Primus, who issued a statement after the CSAC's announcement.

"Today I was informed by Andy Foster that my opponent from Bellator 300 Usman Nurmagomedov tested positive for a banned substance and the fight is now ruled a No Contest. I'd like to thank CSAC and Bellator for working together to promote a clean sport. I'm in the gym training hard and will be ready to get back into the Grand Prix."

Prior to the Primus bout, Nurmagomedov had gone 17-0 lifetime (6-0 in Bellator) with eight knockouts and six submissions. He defeated Pitbull to win the Bellator lightweight title in Nov. 2022 via unanimous decision and defended his crown once against Benson Henderson in the Grand Prix quarterfinals via first-round submission last March.
