Look back at the origin of Regian Eersel’s rivalry against Sinsamut Klinmee

ONE Championship re-posted Regian Eersel’s first fight against Sinsamut Klinmee.

In October 2022, Eersel made his promotional Muay Thai debut after dominating the lightweight kickboxing division. ‘The Immortal’ and Sinsamut fought for the inaugural ONE lightweight Muay Thai world title, leading to a five-round war. Once the dust settled, the Suriname-born fighter emerged victorious by a close split decision.

Ahead of Eersel’s second Muay Thai world title defense, the promotion shared his entire fight against Klinmee on YouTube with the caption saying:

“Before two-sport ONE World Champion Regian Eersel defends his lightweight Muay Thai throne against Russian knockout artist Dmitry Menshikov on June 9, relive his crowning moment against Thai striking sensation Sinsamut in 2022!”

Five months after their first fight, Regian Eersel and Sinsamut Klinmee fought for a second time. Eersel silenced the doubters in the rematch at ONE Friday Fights 9, leading to a fourth-round knockout.

‘The Immortal’ has been unbeatable since his promotional debut in April 2018. The Suriname-born fighter won all seven of his kickboxing fights, including five world title bouts, before focusing on “the art of eight limbs.”

On June 9, Eersel returns to action for his second ONE lightweight Muay Thai world title defense. The 30-year-old will headline ONE Fight Night 11: Eersel vs. Menshikov on Prime Video alongside Dmitry Menshikov. The Russian-born fighter is making his promotional debut and plans to end his opponent’s reign of terror.

ONE Fight Night 11 goes down inside the legendary Lumpinee Boxing Stadium in Bangkok, Thailand. The event can be seen live and for free by North American Prime Video subscribers.
