Former World Title Challengers Sinsamut Klinmee And George Jarvis To Collide At ONE Fight Night 41
Following a blockbuster submission grappling title match announcement, ONE Championship has unveiled another marquee matchup for ONE Fight Night 41 on Prime Video.
Thai knockout artist Sinsamut Klinmee faces British destroyer George “G-Unit” Jarvis in a crucial lightweight Muay Thai clash, broadcasting live in U.S. primetime from Bangkok’s Lumpinee Stadium on Friday, March 13.
The showdown features two fighters seeking redemption after recent setbacks, making this encounter critical for their ONE World Title aspirations.
Sinsamut returns to his Muay Thai roots after a brief kickboxing detour. The Team Mehdi Zatout standout brings an impressive 83-21 career slate built since his journey through the sport began at just 4 years old.
His promotional arrival made immediate waves at ONE X in March 2022, where he demolished Dutch striking legend Nieky Holzken with a stunning one-punch knockout. Four months later, he erased any doubts by knocking out “Lethal” Liam Nolan, establishing himself as a legitimate lightweight Muay Thai threat.
Those performances earned him a shot at the inaugural ONE Lightweight Muay Thai World Championship against divisional kickboxing kingpin Regian Eersel at ONE on Prime Video 3 in 2022.
The 30-year-old Thai star pushed the Dutch-Surinamese athlete through five grueling rounds before falling short via split decision.
Their March 2023 rematch ended more decisively with Eersel securing a knockout victory.
Sinsamut then rebounded with two wins in 2023 before enduring a challenging 2024 that saw him drop two consecutive bouts to Dmitry Menshikov and Youssef Assouik. He roared back with a TKO victory over Nauzet Trujillo at ONE 170, showcasing his indomitable spirit.
His most recent outing featured him returning to kickboxing against Holzken, suffering a knockout defeat. Now he refocuses on Muay Thai to reignite his pursuit for 26 pounds of gold.
On the other hand, Jarvis brings youth and knockout power to this pivotal matchup.
The Lumpini Crawley representative holds a 27-5 professional record and 4-2 promotional mark. After a narrow split-decision debut loss to Chanajon PK Saenchai in September 2023, he strung together impressive victories over Mustafa Al Tekreeti and Ricardo Bravo in the ONE Friday Fights series.
His breakthrough moment arrived at ONE Friday Fights 85 in November 2024, when he spectacularly knocked out Thai veteran Rungrawee “Legatron” Sitsongpeenong to secure a six-figure main roster contract.
The Englishman made his U.S. primetime debut count at ONE Fight Night 30 in April 2025, dominating Mouhcine Chafi via unanimous decision. Riding a four-fight winning streak, he challenged Eersel for lightweight Muay Thai gold but absorbed a first-round knockout defeat.
Now, March’s lightweight showdown will deliver redemption stakes for one of these former ONE World Title challengers in Bangkok.
