The ONE Championship arrival of Ukrainian professional mixed martial artist Alyona Rassohyna, 30, is a remarkable one. While making her promotional debut, she broke the undefeated professional MMA record of her opponent Natthawan Panthong (แสตมป์ แฟร์เท็กซ์), 23, of Thailand, who is professionally known as Stamp Fairtex.

On January 22, 2021, Stamp and Alyona Rassohyna, 30, of Ukraine headlined “ONE: Unbreakable 3” at the Singapore Indoor Stadium in Kallang, Singapore. They battled it out in the atomweight division.

Olivier Coste served as the referee. He put a stop to the atomweight contest just one minute before the end of the third and final round when Rassohyna submitted Stamp via guillotine choke.

“I didn’t tap! I didn’t tap!” Stamp repeatedly said right after the fight. However, a slo-mo replay of the final seconds of the match showed otherwise.


Featuring six MMA matches, “ONE: Unbreakable 3” marked Rassohyna’s ONE Championship debut. She now holds a professional MMA record of 13 wins and 4 losses.

It was a remarkable comeback for the Ukrainian MMA fighter. She went on hiatus in 2020 after having one win in 2018 and one win in 2019, both via armbar submission in Word Warriors Fighting Championship.


Losing to Rassohyna at “ONE: Unbreakable 3” downgraded Stamp’s professional MMA record to 5 wins and 1 loss. In 2020, she had two MMA wins via technical knockout.

Stamp is one of the very few ONE Championship athletes who also compete in ONE Super Series. She previously held the atomweight championship belts in the striking-only league’s kickboxing and Muay Thai categories.

On July 19, 2018, Stamp made her professional MMA debut in ONE Warrior Series. She went on two win four consecutive MMA wins in ONE Championship from 2019 to 2020.
