The 6-foot-2 Surinamese-Dutch striker has authored one of ONE Championship’s most legendary careers. He won both the inaugural ONE Lightweight Kickboxing and Muay Thai World Titles, establishing himself as a dominant two-sport titleholder.
Coming off a three-fight winning streak, the high-volume, high-flying Dutch-style kickboxer seamlessly transitions between disciplines. Now he aims to reclaim lightweight kickboxing gold and restore his status as a two-sport ONE World Champion.
His opponent brings dangerous Thai striking credentials and devastating leg kicks.
Rungrawee represents Sitsongpeenong with a remarkable 158-48 career record and 6-2 promotional mark. The Thai striker earned his “Legatron” moniker through devastating leg kicks that have crippled countless opponents throughout his storied career.

He launched his ONE career with three consecutive victories, announcing his arrival among the lightweight division’s elite. In his most recent outing, Rungrawee claimed a unanimous decision victory over Youssef Assouik at ONE Fight Night 34 last August. Now the Thai star gets his opportunity to capture 26 pounds of gold and cement his legacy in the world’s largest martial arts organization.
Meanwhile, the new ONE Fight Night 42 main event between Mann and Dzhabrailov delivers an explosive welterweight MMA collision between two high-flying stars, in a fight that carries major World Title implications.
Mann comes into the contest with an unblemished 7-0 career record, including five finishes, and he is primed for his biggest test yet on the global stage. The Arkansas native made his ONE debut in January this year against Isi “Doxz” Fitikefu, winning via TKO to maintain his unbeaten run.

This represents Mann’s first main event on the global stage in U.S. primetime — a massive opportunity to showcase his skills to North American audiences. He’ll look to continue his winning streak and defeat his unbeaten opponent to stamp his authority in the welterweight division.
Standing across from him is explosive Turkish knockout artist Dzhabrailov.
The 21-year-old fights out of Team Amir in Turkey, and boasts a perfect 6-0 professional MMA record, with all victories coming via finish. His 3-0 promotional record has been nothing short of spectacular.
Since making his ONE debut in 2024, Dzhabrailov has demolished all three opponents inside the two-minute mark via stoppage. His aggressive, all-out attacking style overwhelms opponents before they can establish any rhythm, making him one of welterweight MMA’s most dangerous stars.
The stakes extend beyond protecting perfect records. The winner of Mann vs. Dzhabrailov could potentially emerge as the next challenger for reigning ONE Lightweight and Welterweight MMA World Champion Christian “The Warrior” Lee, so there’s plenty at stake in this incredible matchup.
