Regian Eersel Powers Through Broken Arm to Retain ONE Lightweight Muay Thai World Title With Fourth-Round Knockout Of George Jarvis
October 2, 2026 – Bangkok, Thailand: ONE Championship (ONE), the world’s largest martial arts organization, returned to the iconic Lumpinee Stadium for another exciting evening at The Inner Circle 33, which aired exclusively for members at live.onefc.com.
In the main event, two-sport ONE World Champion Regian Eersel successfully defended his ONE Lightweight Muay Thai World Title in a grueling, back-and-forth rematch, stopping English challenger George “G-Unit” Jarvis with a fourth-round knockout.
The opening frames delivered explosive exchanges as both men traded devastating blows. Jarvis initiated the damage, punishing the champion with a massive right hand and a follow-up left hook to score a dramatic first-round knockdown.
Despite wearing a gruesome welt under his right eye, the English challenger surged forward in the second stanza. However, Eersel quickly shook off the damage, answering with a stiff one-two and a crisp left hook of his own to drop Jarvis and instantly even the score.
Fighting through a broken right arm sustained in the second round, “The Immortal” adjusted to rely entirely on his left side as the bout progressed. Eersel meticulously targeted Jarvis’ severely compromised right eye in the fourth round, ultimately uncorking a sweeping left hook that sent “G-Unit” crashing to the canvas. Visibly clutching his eye, Jarvis was unable to answer the referee’s count, sealing the knockout victory for Eersel at the 1:39 mark.
In the co-main event, Thai prodigy Duangdawnoi “Little Star” Looksaikongdin delivered a technical striking performance, securing a unanimous decision victory over Swiss standout Aline Seiberth in their women’s atomweight Muay Thai clash.
With former ONE Flyweight Muay Thai World Champion Rodtang “The Iron Man” Jitmuangnon lending his expertise in her corner, Duangdawnoi set an explosive tone immediately, dropping Seiberth with a perfectly timed head kick in the opening moments. Though the Swiss striker displayed immense durability to beat the count and consistently press forward, “Little Star” expertly managed the distance, utilizing sharp teeps and crisp counters off the back foot to neutralize the aggression.
Duangdawnoi continued to showcase her expansive arsenal in the later rounds, repeatedly catching Seiberth with precise step-through elbows and thudding switch kicks. Whenever Seiberth managed to close the distance or land a clean right hand, the Thai standout promptly answered back to maintain control. Comfortably ahead on the scorecards, Duangdawnoi safely navigated the final three minutes on the defensive to easily secure the nod from the judges.
