Regian Eersel defended his ONE Championship lightweight Muay Thai title for the fourth time by defeating George Jarvis via a fourth-round knockout at The Inner Circle 33 event on Friday, October 2, 2026, at Lumpinee Boxing Stadium in Bangkok, declaring his intention to rule the division for a long time.
The Championship Fight and Mid-Match Adversity
Facing George Jarvis in a high-stakes rematch at Lumpinee Boxing Stadium, Eersel found himself in immediate trouble during the opening frame. Jarvis landed a sharp combination that scored a knockdown, putting the champion on the defensive. Eersel, known by his moniker “The Immortal,” kept his composure after absorbing the early blow.
The momentum shifted back in the second round when Eersel answered with a knockdown of his own. However, complications arose immediately after as Eersel suffered a broken arm during the exchange. Refusing to yield, the 33-year-old champion came out of his corner for the third stanza relying solely on his remaining limb.
Overcoming Injury to Secure the Finish
Fighting with a compromised arm required a strict tactical adjustment. Eersel depended entirely on his left hook to manage distance and dismantle his challenger over the championship rounds.

In the fourth round, the strategy paid off. Eersel landed a decisive left hook that ended the contest, sealing the knockout victory and retaining his belt.
