Stamp Fairtex has agreed to relinquish her ONE women’s atomweight MMA world championship title after she suffered a heartbreaking injury during rehab for her left knee.
The Thai megastar had to withdraw from her world title unification bout against Denice Zamboanga, the ONE interim women’s atomweight MMA world champion, at ONE 173: Denver, which was originally scheduled for Aug. 1 at Ball Arena in Denver.
Zamboanga, in turn, has now been elevated to undisputed ONE women’s atomweight MMA world champion. According to a press release, ONE Championship will move its Denver event to June 26, 2026, after Stamp’s withdrawal and a few world title matches not materializing.
ONE Championship CEO Chatri Sityodtong said in the statement:
