Club Level Seating: ONE: DENVER

The worlds greatest martial artists will return to the Mile High City for ONE Championships third blockbuster spectacle in the United States, ONE 173: Denver, which emanates live from Ball Arena in Colorado on Friday, August 1.

Stamp Fairtex, the divisions reigning queen, is finally ready to make her long-awaited return to the Circle and compete for the first time since suffering a torn meniscus in May 2024. But standing across from her will be Denice Zamboanga, the interim champion who used to hang out and train side-by-side with the Thai megastar several years ago at Fairtex Training Center.
