Rungrawee Vs. George Jarvis II Set To Headline ONE Fight Night 44 In June
ONE Championship has officially unveiled the blockbuster main event for ONE Fight Night 44 on Prime Video. In a highly anticipated lightweight Muay Thai rematch, former ONE World Title challengers Rungrawee “Legatron” Sitsongpeenong and George “G-Unit” Jarvis are set to run it back.
The spectacular showdown broadcasts live in U.S. primetime on Friday, June 26, from Bangkok’s iconic Lumpinee Stadium.
The pair first clashed in November 2024 at ONE Friday Fights 85, where Jarvis delivered one of the absolute standout performances of his career. The English striker dominated his highly experienced Thai rival with relentless forward pressure before closing the show in the third round via a devastating knockout.
That monumental victory was as significant as it gets for the 25-year-old Lumpini Crawley product, earning him a coveted US$100,000 contract and a permanent spot on ONE’s global roster in one unforgettable night.
However, since that setback, Rungrawee has wasted absolutely no time proving that the loss was merely a bump in the road and not a true reflection of his elite standing in the lightweight Muay Thai ranks.
The 30-year-old Sitsongpeenong veteran, whose crippling leg kicks earned him the famous moniker “Legatron,” boasts an incredible 158-49 career record with 50 finishes. His 6-3 promotional slate is built on some of the most resilient and thrilling performances the division has ever seen.
He bounced back from the Jarvis defeat with a dominant unanimous decision win over Youssef Assouik, which ultimately earned him a shot at reigning ONE Lightweight Muay Thai World Champion Regian “The Immortal” Eersel.
At The Inner Circle on April 10, the Thai warrior pushed the defending king the full five-round distance before falling just short via decision—a gutsy performance that underlined exactly how much he has evolved since he last shared the ring with “G-Unit.”
Jarvis, meanwhile, has continued his own upward trajectory since claiming the life-changing contract. The highly technical striker, who brilliantly switches stances to keep opponents guessing, fell short in his own ONE Lightweight Muay Thai World Championship challenge against Eersel in August 2025.
He responded in characteristic fashion, returning to action this past March and defeating Thai superstar Sinsamut “Aquaman” Klinmee in a brutal, high-octane three-round firefight that instantly reignited his World Title ambitions.
A second consecutive win over Rungrawee—now a proven, battle-tested World Title challenger in his own right—would make a highly compelling case for another crack at the lightweight Muay Thai crown.
When the same two elite martial artists meet with this much tremendous growth, this much history, and this much at stake, the result is a massive rematch that promises to surpass the original in every conceivable way.
