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. In one of the featured bouts of the night, a pair of close friends and former training partners will collide in a ONE Womens Atomweight MMA World Title unification match. 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. Now, the two ladies will put their friendship aside and go to war to find out who the best female atomweight mixed martial artist on the planet truly is. More explosive bouts will be announced in the weeks to come.
