ONE confirmed Stamp Fairtex vs. Selina Flores for ONE Fight Night 47, putting the former three-sport champion back in an atomweight Muay Thai bout after her June return.
The card takes place Friday, Sept. 4 at Lumpinee Stadium in Bangkok, Thailand, and airs in U.S. primetime on Prime Video. ONE also added Jaosuayai Mor Krungthepthonburi vs. Jordan Estupinan in flyweight Muay Thai.
Stamp beat Cynthia Flores by split decision at The Inner Circle 20 in June. That result followed the knee injury layoff that interrupted her run after she became ONE women’s atomweight MMA champion by stopping Seo Hee Ham at ONE Fight Night 14.

Stamp Stays In A Striking Lane
Stamp’s appeal is still built on the rare resume. She has held ONE atomweight gold in MMA, Muay Thai, and kickboxing, and her next assignment keeps her in the stand-up lane while the atomweight title picture settles around champion Allycia Hellen Rodrigues.
Flores gives the matchup a real specialist on the other side. ONE described her as a multi-time WBC Muay Thai world champion who brought a four-fight winning streak into her promotional debut, then extended that run with a decision over Marie McManamon.
For Stamp, beating Selina Flores would add another win to a comeback year built around ring time and durability. For Flores, a victory over Stamp would be the biggest name result of her ONE run.
Jaosuayai Meets Estupinan On The Same Card
Jaosuayai enters the Estupinan bout trying to stop a three-fight skid. His biggest ONE moment remains the 52-second head-kick knockout of Nakrob Fairtex, a finish that earned him a $50,000 bonus.
Estupinan also needs a reset after consecutive losses. The Colombian opened his professional run at 9-0 with ONE wins over Ali Saldoev and Freddie Haggerty before the streak stalled.
ONE Fight Night 47 now carries Stamp’s return bout, a second Muay Thai booking with Jaosuayai and Estupinan, and another Lumpinee Stadium date on the September schedule. Stamp’s earlier title run remains tied to her Seo Hee Ham stoppage at ONE Fight Night 14, while recent ONE coverage includes Viet Anh Do vs. Davi Brandao at ONE Fight Night 46 and Anastasia Nikolakakos calling for a title shot at ONE Fight Night 45.
