ONE Fight Night 25: Regian Eersel Reclaims Lightweight Kickboxing World Title

Regian ‘The Immortal’ Eersel has once again become a two-division world champion after a spectacular five-round fight against Alexis ‘Barboza’ Nicolas.

In the main event of ONE Fight Night 25, held in Bangkok’s Lumpinee Stadium, the Dutch-Surinamese fighter secured a unanimous decision victory. This win allowed him to regain the ONE Lightweight Kickboxing World Title, which he had previously lost to Nicolas earlier this year.

Eersel, 31, now proudly holds both the ONE Championship lightweight kickboxing and Muay Thai world titles.

Eersel immediately took the initiative, pressuring Nicolas from the start of the fight.

Although Nicolas attempted to counter, ‘The Immortal’ allowed him little space, consistently landing effective strikes such as leg kicks, knees, jabs, and crosses to the face.

Nicolas increased his offensive output in the later championship rounds, but Eersel maintained relentless pressure until the final bell, securing his victory.

This victory marks Eersel’s return to winning form after his impressive 22-fight win streak was broken by ‘Barboza’ at ONE Fight Night 21 in April.

For Nicolas, this fight represents the first loss in his professional career.
