ONE Championship returns with another action-packed event on Saturday, March 14, as ONE Fight Night 41 goes live from Bangkok's iconic Lumpinee Stadium. The card features nine bouts across MMA, Muay Thai, kickboxing, and submission grappling.
The main event features a crucial lightweight Muay Thai showdown between Thailand's Sinsamut Klinmee and England's George Jarvis. Both fighters are former ONE World Title challengers and will be looking to bounce back with a win that could move them closer to another shot at reigning champion Regian Eersel.

Thirty-year-old Sinsamut, nicknamed "Aquaman," returns after spending a year away from competition to focus on family life following the birth of his second child. Hailing from a well-known fighting family, the Thai striker brings with him an impressive record of 83 career victories.
Jarvis, a former WBC Muay Thai World Champion, finds himself in a similar position. The 25-year-old British fighter, known as "G-Unit," is aiming to rebuild momentum after falling to Eersel last August. Jarvis has long called for a matchup with Sinsamut and finally gets the opportunity in Bangkok.
The co-main event will see the ONE Welterweight Submission Grappling World Title on the line as defending champion Tye Ruotolo takes on Poland's Pawel Jaworski. The bout pits two of the most exciting young talents in Brazilian Jiu-Jitsu against each other.
Since joining ONE Championship in 2022, the 23-year-old American has been dominant. Ruotolo captured the inaugural welterweight submission grappling crown in November 2023 and defended it twice while compiling a perfect 10-0 promotional record in grappling and MMA.
Jaworski, known for his dangerous leg-lock game, will be aiming to hand Ruotolo his first defeat in the promotion. A victory over the reigning champion would mark a major breakthrough and establish him among the sport's elite.
Elsewhere on the card, former ONE Bantamweight MMA World Champion John Lineker continues his move into striking sports when he faces British kickboxing champion Ben Woolliss. The Brazilian "Hands of Stone" has enjoyed success since switching focus to stand-up competition in September 2024.
Lineker scored knockout wins over Asa Ten Pow and Alexey Balyko in Muay Thai before testing himself against some of the division's best strikers. He now meets Woolliss, who enters the promotion with a strong 29-6 kickboxing record.
