Regian “The Immortal” Eersel will defend his ONE Lightweight Muay Thai World Title against George “G-Unit” Jarvis in a rematch headlining The Inner Circle 33 on Friday, October 2, at Bangkok’s Lumpinee Stadium, with the full five-bout card now set by ONE Championship.
The show streams exclusively for members at live.onefc.com in Asia primetime. Their first meeting, at ONE Fight Night 34 in August 2025, lasted 84 seconds — Eersel stopped the Englishman with a combination that ended the title shot before it could settle into a fight.
Eersel, the 33-year-old Suriname-born, Amsterdam-based Sityodtong Amsterdam product, sits among ONE’s most decorated lightweights: seven ONE Lightweight Kickboxing World Title wins and four ONE Lightweight Muay Thai World Title wins, a 65-5 career striking record with 29 finishes, and a 14-1 promotional ledger. He took the inaugural kickboxing crown in May 2019 and added the inaugural Muay Thai belt in October 2022 by beating Sinsamut Klinmee. His most recent kickboxing title win was a unanimous decision over Rungrawee Sitsongpeenong at The Inner Circle 10.
Jarvis, a 26-year-old former WBC Muay Thai World Champion out of Lumpini Crawley, returns with a 28-5 career striking record and a 6-2 ONE ledger. After losing his ONE Friday Fights debut in 2023, the 6-foot British striker stacked four straight wins, earned a six-figure main-roster contract, and got the first crack at Eersel. Since that 84-second loss he has beaten former title challenger Sinsamut and scored a rematch knockout of Rungrawee — a finish Eersel did not get in their own meeting with Rungrawee. Jarvis has now knocked Rungrawee out twice.
In the atomweight Muay Thai co-main, undefeated Thai Duangdawnoi “Little Star” Looksaikongdin (three wins from three ONE bouts) meets Switzerland’s Aline Seiberth, a WBC Muay Thai European Champion with 30 professional wins. The 27-year-old Duangdawnoi, who has a family connection to former ONE Flyweight Muay Thai World Champion Rodtang Jitmuangnon, most recently scored a bonus-winning second-round knockout of Regan “Coconut” Gowing at ONE Friday Fights 137 last December.
