Helena native Sean "Sugar" O'Malley celebrates his ninth MMA victory, and debut UFC win, in 2017.

Helena native and current Ultimate Fighting Championship bantamweight Sean O'Malley won't be fighting next Saturday on the prelims of the highly anticipated UFC 229 card in Las Vegas, he announced on Instagram Sunday. 

O'Malley (10-0 MMA, 2-0 UFC) was scheduled to fight Jose Quinonez (7-2 MMA, 4-1 UFC) in the headlining fight of the Conor McGregor vs. Khabib Nurmagomedov prelim card. 

Instead, O'Malley says he believes he has been flagged for a potential U.S. Anti Doping Agency violation due to a tainted supplement and is working to rectify his situation. 

UFC and USADA recently announced changes that make potential violations private until a resolution is made, according to MMAJunkie.com. O'Malley said in his post he was updating his fans in the interest of honesty. 

"Even though under the new policy, my case would not be public right now, I feel it’s important to be upfront and honest with my fans about why I’m not fighting next weekend," his post reads.

It continues: “I’ve been working with Jeff Novitzky at UFC and I believe that we have already identified a dietary supplement that would have caused this. We’ve sent remaining samples from the bottle I took to the USADA lab and as well as a full sealed bottle. I’m told that the testing of these supplements can take as long as 30 days."

The UFC has not yet commented on the status of its rising 135-pound star from Montana. 

O'Malley concludes his post with a promise to return to the octagon soon. 

“I will continue to update you all about the findings, but I fully expect the results will be what I already know, that I did nothing on purpose.

“For everyone that follows me and was excited for my fight I’m truly sorry. It hurts a lot not being able to get out there and do what I love on the biggest stage.

“I have no intention of cheating and am fully confident that the results of this case will show that. I love my fans and I hope the impact on my career is minimal and I’m back to fighting soon.”
