ONE Championship

Seven times, ONE’s lightweight kickboxing crown has ended up around the same waist. The lightweight Muay Thai belt has followed four times, and its current owner is about to defend it against a familiar face.

Regian Eersel puts his ONE Lightweight Muay Thai World Title up against George “G-Unit” Jarvis in the main event of The Inner Circle 33 on Friday, October 2. The five-bout card streams exclusively for members from Lumpinee Stadium in Bangkok, Thailand.

The Suriname-born, Amsterdam-based striker has lost so rarely that his career defeats can be counted on one hand. He has defended gold in two of the most demanding striking disciplines on the planet.

His most recent kickboxing title win came via unanimous decision over Rungrawee Sitsongpeenong at The Inner Circle 10. That performance showed the two-sport king had not lost a step.

His most recent Muay Thai outing, meanwhile, was the first meeting with Jarvis at ONE Fight Night 34 in August 2025. It lasted 84 seconds before a combination left no room for argument.

That result reinforced his standing as one of the most technically complete strikers in the world. The rematch now tests whether a second look changes anything.

Few titleholders in ONE history have been as dominant. On Friday, he looks to extend that run against the man he dispatched last year.

Regian Eersel meets a challenger with Rungrawee history

Jarvis, a 26-year-old Englishman and former WBC Muay Thai World Champion, owns two knockouts of Rungrawee, a feat Eersel never achieved. He has spent every day since their first fight working toward another result, and dethroning the most successful lightweight striker in ONE history would stand as a generational statement.

The co-main event pits unbeaten atomweight Duangdawnoi Looksaikongdin, whose bonus-winning knockout of Regan “Coconut” Gowing came at ONE Friday Fights 137 last December, against Switzerland’s Aline Seiberth, a WBC European titleholder with 30 professional wins. Dzhamil Osmanov vs. Ben Woolliss, Mia Trevorrow vs. Sheila Barrios, and Fahlap Toyotarayong vs. Yugo Kato round out the lineup.
