One down, more to go.

UFC light heavyweight champion Jon Jones today came back negative for performance-enhancers – including the M3 metabolite of oral turinabol – and drugs of abuse on a fight-night test at UFC 232.

Jones was tested by the California State Athletic Commission, which oversaw the Dec. 29 pay-per-view event at The Forum in Inglewood, Calif., and UFC anti-doping partner U.S. Anti-Doping Agency.

CSAC Executive Director Andy Foster confirmed the news to MMAjunkie following an initial report from from ESPN.com‘s Brett Okamoto.

Jones (23-1 MMA, 17-1 UFC) was also ordered to participate in a drug testing program administered by the Voluntary Anti-Doping Association (VADA) for his rematch with Alexander Gustafsson (18-5 MMA, 10-5 UFC), which he won by third-round TKO to reclaim the UFC light heavyweight title. The results of that testing have not yet been announced.

UFC 232 took place Dec. 29 at The Forum in Inglewood, Calif. The main card aired on pay-per-view following prelims on FS1 and UFC Fight Pass.

UFC 232 was moved from Nevada to California on six days’ notice when an abnormal out-of-competition test given to Jones on Dec. 9 revealed trace amounts of the M3 metabolite that resulted in a 15-month suspension after UFC 214 in 2017.

USADA ruled the adverse result wasn’t an anti-doping violation after consulting with experts who said the positive, one of three such tests interspersed between five clean tests, was the result of a “pulsing effect” that could cause the metabolities to linger in his system for an unknown amount of time.

Jones, who’s twice been sanctioned by USADA for anti-doping violations, denied again using performance-enhancers and claimed the UFC’s anti-doping partner had vindicated him. Still, the UFC’s decision to move the event drew fierce backlash from MMA fans and observers.

Next up for Jones is an evidentiary hearing before the Nevada State Athletic Commission, which allowed him to withdraw his UFC 232 license application. NSAC Executive Director Bob Bennett called the Dec. 9 test an “adverse” finding, and the commission announced it would look into Jones’ case for a “measured, thoughtful, and comprehensive discussion of his anti-doping testing protocol and results and provide an opportunity for the NSAC to determine the appropriate path forward for him in Nevada.”

Recently scheduled to fight Anthony Smith at UFC 235, Jones needs a license for the March 2 pay-per-view card at T-Mobile Arena in Las Vegas. UFC President Dana White said he’d be “shocked” if the commission doesn’t license Jones.

Jones, who holds a virtually unblemished record, is a massive favorite to defeat Smith. White believes a trilogy fight with rival and former two-division champ Daniel Cormier could be on the horizon. Cormier was stripped of the light-heavy title belt prior to Jones’ return and is expected to defend his heavyweight title next.
