One Championship Scuttles Denver Card After Stamp Fairtex Injury, Vacated Title

One Championship had to stamp out an event when its marquee star suffered another injury.

On Friday, the organization sent out a press release announcing that its August show in Denver has been pushed back a year. The expectation is that organization will travel to Colorado in 2026 instead, at the same location of the Ball Arena. ONE atomweight champ Stamp Fairtex re-injured her knee, and she has vacated her belt and allowed interim titleholder Denice Zamboanga to claim the undisputed throne.

ONE head Chatri Sityodtong included his own statement in the release, confirming the details while wishing the former champ well.

“We are saddened to hear of the injury setback to Stamp and wish her nothing but the best in her road to recovery,” the ONE founder wrote. “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.”

The multi-sport combatant last competed at One on Prime 14 in September 2023, where she put Seo Hee Ham away with body shots to reclaim the 115-pound belt. The year of 2023 overall proved fruitful for the woman born Nadthawan Panthong, as she also knocked out Alyse Anderson before the Ham match and beat Supergirl Jaroonsak in a muay thai excursion.

Stamp was originally slated to battle Zamboanga in early 2024, and that was bumped for documentary filming purposes. An injury to Stamp scratched that matchup, and she was later booked to fight Xiong Jing Nan up a weight class. That too fell apart due to another injury.
