Stamp Fairtex Opens Up on Losing Her 'Killer Instinct' Before Selina Flores Fight

The 28-year-old Thai megastar returns to the ring against American Selina "Teep Queen" Flores in an atomweight Muay Thai main event at ONE Fight Night 47. It goes down in U.S. primetime on Friday, September 4, and North American fans can stream it live via Prime Video.

Stamp is one of the most decorated athletes in ONE Championship history, the only fighter to have held the promotion’s atomweight Muay Thai, kickboxing, and MMA titles.

A serious knee injury in 2024 disrupted the MMA title reign she had worked years to build, and the road back to competition has been defined as much by psychological recovery as physical rehabilitation.

Her comeback kickboxing loss to Japanese veteran Kana in November last year and a narrow split-decision Muay Thai win over Cynthia Flores in June have raised questions she has now addressed directly.

Stamp Admits Her Last Fight Was 'Bad'

The Cynthia Flores split-decision win in June was a result Stamp has not allowed herself to celebrate. The former champion watched the comments section and heard what was being said, and she has concluded there was truth in the criticism.

"My last fight was bad. That was the most disappointed I've ever been with myself after a fight. I saw some comments saying Stamp doesn't have that killer instinct anymore, and I think there was a little truth to that because I didn't feel very fresh," Stamp confessed.

A 15-5 ONE Championship record across Muay Thai, kickboxing, and MMA and three world title reigns give her the credibility to put a single subpar performance in perspective. But the honesty with which she has framed the Flores win reflects a champion holding herself to a standard that a narrow decision victory does not satisfy.

Fear of Getting Hurt Again Made Stamp Fight Safe

The deeper reason behind the killer instinct that went missing has now been identified. Stamp has traced the problem back to a psychological constraint that emerged from the injury and the lengthy rehabilitation that followed it.

"Looking back at that fight, I must say I felt like I wanted to become the old Stamp again. I tried to push myself, but there was still a little voice saying, 'What if I get hurt again?' So, part of me thought I should play it safe and fight smarter," she explained.

Flores, 28, arrives from Vista, San Diego, as a former WBC Muay Thai World Champion with a 9-1 professional record and a victorious ONE Championship debut over Marie McManamon last year.

Stamp Feels the Pressure to Return to Her Old Self

The pressure bearing down on Stamp heading into ONE Fight Night 47 is not coming from one direction. It is coming from the fans, from the expectations attached to her name, and from within.

"Honestly, there's a lot of pressure for this fight because a lot of people expect me to come back and be the same as before. Even I expect that from myself too. I want to fight the way I used to and be the version of myself that I was back then. But things have changed," she said.

The acknowledgment that things have changed is perhaps the most important thing Stamp has said ahead of September 4. The old Stamp captured three world titles in three disciplines through a combination of explosiveness, fearlessness, and finishing instinct. Recapturing all of that against a hungry American challenger in U.S. primetime is the most honest measure of where her comeback truly stands.
