George Jarvis knocked Rungrawee Sitsongpeenong out in November 2024 and walked away with a six-figure contract. Eighteen months later, Rungrawee has challenged for a ONE World Title. Jarvis knows the man across from him has changed.
Rungrawee faces Jarvis in a lightweight Muay Thai rematch in the main event of ONE Fight Night 44 on Prime Video, broadcasting live in U.S. primetime from Lumpinee Stadium in Bangkok, Thailand on Friday, June 26.
Their first meeting at ONE Friday Fights 85 in November 2024 ended in a third-round knockout that launched Jarvis onto the global roster and handed Rungrawee the first serious setback of his ONE Championship run.
The 30-year-old Thai responded by winning a dominant unanimous decision over Youssef Assouik and then pushing reigning ONE Lightweight Kickboxing World Champion Regian Eersel the full five rounds in April before falling just short via decision. A second loss to Jarvis would stall what has become one of the division’s most compelling runs. A win would make the case for another title shot undeniable.
Jarvis, 25, has not stood still either. After earning his contract with the Rungrawee finish, he challenged Eersel for the ONE Lightweight Muay Thai World Title in August 2025 and came up short before returning to form with a three-round win over Sinsamut Klinmee in March 2026. His combination of stance-switching and technical precision has made him one of the division’s most unpredictable strikers.
George Jarvis, Rungrawee aim for second shot at ONE World Title
The matchup carries genuine title implications for whoever wins. Both Rungrawee and Jarvis have already tested themselves against the ONE Lightweight Kickboxing World Champion and come within reach of the belt. A convincing performance on June 26 by either man would make a third shot at Eersel difficult to ignore.
Rungrawee enters having absorbed more high-level competition since their first fight than at any previous point in his career. The crippling leg kicks that earned him the “Legatron” nickname have been sharpened through a world title camp. Jarvis enters knowing that a second win would define his place in the division permanently.
