ONE World Championship Inner Circle 20: Stamp Fairtex Returns To Muay Thai To Face Cynthia Flores On 26 June

Former three-sport ONE World Champion Stamp Fairtex will return to Muay Thai after six years away when she faces Mexican striker Cynthia Flores in an atomweight bout at The Inner Circle 20 on Friday, 26 June. The event will stream live on live.onefc.com.

The 28-year-old Thai star began training in Muay Thai at age five and later won World Titles across three ONE Championship rule sets. A serious knee injury forced her to give up her MMA title in 2025, and months of rehabilitation kept her out of action before she returned to full fitness.

Stamp returns to her roots

Stamp said taking a Muay Thai fight after such a long break felt right. "Accepting a Muay Thai fight after six years away feels amazing. It feels like I'm finally returning to my roots, returning to the sport I've been competing in since I was a kid," Stamp said.

Flores, 31, represents Phuket Fight Club and holds a 25-7 record. She fought twice in ONE last year and lost both bouts. Against a three-sport champion, she will look for the biggest win of her career in the June 26 contest.

Game plan and long-term aim

Stamp has already outlined her plan for the match. She expects Flores to rely on punches and wants to answer with elbows in close range. "For this fight, I think I'm going to focus a lot more on using my elbows. Since she's a puncher, she's going to rely heavily on her hands. When someone comes in with punches, the shortest weapon to counter them is the elbow," She said.

Her wider goal remains clear: reclaim the ONE Atomweight MMA World Title. Stamp said she wants one or two striking fights first to rebuild rhythm and improve her cardio before returning to MMA, which she said places heavy demands on her body.
