ONE Championship is gearing up for another touchdown on United States soil this summer.
The Asian martial arts powerhouse announced Thursday that it is set to make its third appearance in its familiar battleground, the “Mile High City,” with ONE 173: Denver on Aug. 1 at Ball Arena in Colorado.
Reigning ONE Women’s Atomweight MMA Champion Stamp Fairtex will feature, taking on interim titleholder Denice Zamboanga in a unification clash.
There’s still more left in the tank for British Muay Thai star Liam Harrison.

“Hitman” will return to ONE Championship this summer. There, he faces Myanmar bruiser Soe Lin Oo at ONE 173: Denver, on Friday, August 1. They will compete in a bantamweight Muay Thai outing that’s not expected to go the distance.
ONE Championship was scheduled to make its “Centennial State” return on Aug. 1 at Ball Arena in Denver, Colo., but a major injury to atomweight champion Stamp Fairtex, as well as other options that “did not come together,” forced the promotion to rebook the card for June 26, 2026.
That’s the second time this year ONE was forced to postpone an event.
“We are saddened to hear of the injury setback to Stamp and wish her nothing but the best in her road to recovery,” ONE CEO Chatri Sityodtong said in today’s release. “After looking at multiple alternate headlining options that unfortunately did not come together, we have made the difficult decision to move our Denver event to June 26.”
