US EditionDenice Zamboanga now undisputed ONE champion as Fairtex pulls out
- Stamp Fairtex relinquished her ONE atomweight title and withdrew from the August 1, 2025, unification bout against Denice Zamboanga in Denver, Colorado.
- Stamp sustained an 80 percent meniscus tear in May 2024, resulting in surgery and setbacks during rehabilitation that prevented her title defense and forced withdrawal.
- Denice Zamboanga won the interim atomweight championship earlier in 2024 and earned a second-round stoppage over Alyona Rassohyna to secure a unification bout.
- Following Stamp’s withdrawal and relinquishment, ONE Championship elevated Zamboanga to undisputed champion and postponed the Denver event to June 26, 2026, citing difficulty in booking other title fights.
- ONE Championship affirmed its commitment to the U.S. Market with future events and monthly Fight Night broadcasts despite challenges from Stamp’s injury and event rescheduling.
