With World Championship gold, title implications, and pride on the line across the thrilling card, this U.S. primetime spectacle demands your full attention. That said, here are five reasons why you must watch ONE Fight Night 41 this Friday.
#1 Former Muay Thai World Title Challengers Collide

The main event between former World Title challengers Sinsamut “Aquaman” Klinmee and George “G-Unit” Jarvis has blockbuster written all over it. The pair have never failed to deliver when the spotlight is at its brightest, and this clash shouldn’t be any different.
Sinsamut’s credentials speak for themselves. The Thai powerhouse, who owns an 83-21 career record, has challenged for the ONE Lightweight Muay Thai World Championship twice, and his five promotional victories include four jaw-dropping knockouts.
The mix of precision and punching power he carries into every contest makes him a nightmare at close range. One mistake is all it takes for the lights to go out against the 30-year-old.

But standing across the ring from him will be Jarvis, a man with the relentless grit and fearlessness to make those mistakes count for nothing.
The Englishman has flourished in war after war across six appearances on the global stage, showcasing his own knockout ability alongside the heart of a lion.
Both warriors return at ONE Fight Night 41 with identical motivation: a bounce-back victory that positions the winner for another shot at Regian “The Immortal” Eersel‘s ONE Lightweight Muay Thai World Title. With the stakes so high between the two certified finishers, this main event has all the ingredients for a night to remember.
#2 Ruotolo Defends His Submission Grappling Gold

One of the sport’s craftiest mat wizards puts his gold on the line in a battle of elite Brazilian Jiu-Jitsu black belts, as Tye Ruotolo defends his ONE Welterweight Submission Grappling World Title against Polish phenom Pawel Jaworski.
Ruotolo, the youngest IBJJF World Champion in history, claimed the division’s inaugural belt at ONE Fight Night 16 in November 2023, and then he successfully defended it twice. Most recently, he defeated Dante Leon via unanimous decision.
After cementing his status at the top of the welterweight submission grappling throne, the California skateboarder made the transition to MMA, where his world-class acumen on the canvas forced undefeated rising stars Adrian “The Phenom” Lee and Shozo “Great Teacher” Isojima to tap out.

Now a perfect 10-0 on the global stage across two sports, Ruotolo returns to his grappling roots. But the hungry challenger waiting for him is no ordinary debutant –Jaworski tore through the European grappling scene with breathtaking efficiency to earn this shot at the crown.
The 21-year-old Polish sensation captured the 2025 IBJJF No-Gi World Championship at 85 kilograms and claimed double gold at the IBJJF No-Gi Europeans, winning both his weight class and the absolute division.
Jaworski’s devastating leg-lock arsenal and submission-first approach should match up well against Ruotolo’s explosiveness and overall technical excellence. When two submission artists capable of producing highlight-reel moments collide in the squared circle, entertainment is inevitable.
#3 Lineker Returns, Welcomes Woolliss To ONE

Former ONE Bantamweight MMA World Champion John “Hands of Stone” Lineker needs no introduction. The Brazilian veteran spent years ripping through the division with his trademark knockout power, accumulating 22 finishes from 37 victories across a storied career.
Then, in 2024, he discovered a second calling. The 35-year-old transitioned to the striking arts and immediately looked at home, blasting “The American Ninja” Asa Ten Pow with a second-round knockout and then putting Alexey Balyko to sleep within three minutes.
Though he encountered setbacks against “Left Meteorite” Ratchasiesan Laochokcharoen and former ONE Bantamweight Kickboxing World Champion Hiroki Akimoto, he pushed both men to their limits and showed that his concussive power remains as lethal as ever.

Whether or not those legendary fists may push him back into the winner’s column at ONE Fight Night 41 remains to be seen. Standing across the ring from him in this featherweight kickboxing duel is Ben Woolliss, who makes his first promotional appearance with a point to prove.
The Grimsby native brings a volatile yet technical style that could be the perfect foil to neutralize the Brazilian’s “Hands of Stone” and pull off one of the most incredible debuts inside the “Madison Square Garden of the East.”
Whether Woolliss can tame that power on the grandest stage in martial arts is the compelling question. Either way, fans should expect fireworks right off the bat in this guaranteed barnburner.
#4 Hyu Looks To Maintain His Perfect Record

Japanese sensation Hyu Iwata has ripped through the opposition under the ONE Championship spotlight, and he’ll look to extend his perfect streak against Thai dynamo Suablack Tor Pran49 in this flyweight kickboxing banger.
The 23-year-old blends flashy techniques with fundamentally sound precision. Rolling thunders, spinning back kicks, lightning-fast combinations – he has displayed them all to rack up an unblemished 12-0 career record, including four victories under the ONE banner.
Another statement performance in Lumpinee Stadium at ONE Fight Night 41 would push the undefeated Japanese standout closer to a shot at the ONE Flyweight Kickboxing World Title.

Looking to do what no man has done to Hyu in his entire career is a dangerous veteran who is hungry for redemption.
Thailand’s Suablack made his name by ripping through the bantamweight division with a perfect 6-0 start in ONE, earning a coveted six-figure contract along the way. A rough patch followed, but the 29-year-old knockout machine is returning as a more refined fighter and has set his sights on a new weight class, as well as his 63rd career victory.
Now making his flyweight debut, the Thai brings genuine finishing power and seasoned ring intelligence to disrupt any unbeaten run. As such, the Japanese star shouldn’t underestimate his forthcoming rival.
#5 Atomweight Stars Set To Light Up Lumpinee

With March being Women’s History Month, ONE Fight Night 41 delivers two compelling atomweight battles that feature the very best female martial artists.
In Muay Thai action, Anna “Supergirl” Jaroonsak returns in search of her 41st career victory, but she’ll have a tough time getting it against Hong Kong’s Yu Yau Pui.
The 22-year-old Thai endured a wave of online criticism following a 2023 knockout loss that nearly convinced her to walk away from the sport. “Supergirl” persevered, and now she’s prepared to resume business and remind the global fanbase that she has not lost the glow that made her must-watch television.
Yu enters the battle with her own score to settle, too. The 33-year-old earned her global roster spot and life-changing contract through five consecutive wins on ONE Friday Fights, and then she impressed with a unanimous decision victory over Lara Fernandez in her U.S. primetime debut. Back-to-back defeats have her motivated to author a spectacular performance and get the 29th win of her career.

In MMA, three-time Brazilian Kickboxing Champion Victoria “Vick” Souza returns after taking time off to give birth and raise her firstborn.
The 28-year-old has her sights on a third straight victory. At ONE 167 in June 2024, she became the first person to submit Itsuki “Android 18” Hirata, and she followed that 91-second submission win with a strong three-round display against Alyse “Lil’ Savage” Anderson to bring her record to 9-2.
Souza’s desire to capture the ONE Women’s Atomweight MMA World Championship has never gone away, but she’ll need to bring her A-Game into this clash against undefeated Canadian debutant Anastasia Nikolakakos, who brings a spotless 5-0 slate into her ONE debut.
With Nikolakakos making her first promotional appearance, she’ll be focused on making a statement – and a triumph over the surging Brazilian contender would certainly accomplish that.
