ONE Championship closes out 2025 with a spectacular U.S. primetime event, as ONE Fight Night 38 takes center stage on Friday, December 5, at Lumpinee Stadium in Bangkok, Thailand.
The organization’s final Prime Video card of the year delivers eight explosive MMA, submission grappling, and Muay Thai bouts across multiple divisions.
From champions to emerging stars to legendary veterans making stunning comebacks, the ONE Fight Night 38 lineup provides something for every combat sports fan seeking world-class action before the calendar turns to 2026. Here’s three reasons why you must watch the action this Friday.
Two ONE World Title Fights Headline Spectacular Card at ONE Fight Night 38
The main event features a compelling stylistic clash, as Brazil’s Fabricio Andrade defends his ONE Bantamweight MMA World Championship against #4-ranked contender Enkh-Orgil Baatarkhuu. The classic striker-versus-grappler matchup promises fireworks, and it features Andrade’s lethal stand-up game stacking up against Baatarkhuu’s relentless grappling and finishing ability.
The Brazilian owns seven promotional victories with six stoppages, remaining undefeated in his MMA appearances inside the ring. Andrade’s only loss in the organization came in a kickboxing world title clash against Jonathan Haggerty, demonstrating his willingness to challenge himself across disciplines. The defending titleholder’s striking arsenal and experience make him arguably the bantamweight MMA division’s most dangerous competitors.
Baatarkhuu presents a legitimate threat with his overwhelming finishing rate, having demolished six of his seven opponents in ONE. The Physical: Asia star’s aggressive grappling style and championship ambitions could produce a dramatic upset if he successfully neutralizes Andrade’s striking advantages.
The event also crowns a new flyweight submission grappling king when Brazil’s ADCC World Champion Diogo Reis battles Japan’s Daiki Yonekura for the vacant ONE Flyweight Submission Grappling World Title. Reis impressed in his promotional debut with a slick submission victory over Japanese grappler Shoya Ishiguro, immediately establishing himself as a serious title contender.
Clash of BJJ Legends at ONE Fight Night 38
Brazilian Jiu-Jitsu enthusiasts will witness history at ONE Fight Night 38 when submission grappling GOAT Marcelo Garcia faces Australian veteran Lachlan Giles in a lightweight clash that transcends typical matchmaking. The legendary showdown brings together two of the sport’s most respected figures in what promises to be a masterpiece.
The 42-year-old Garcia’s return from stomach cancer ranks among the most inspiring comeback stories in martial arts history. The nine-time World Champion emerged from a 15-year competitive hiatus to submit Japanese legend Masakazu Imanari in January 2025, proving his skills remain sharp despite the lengthy layoff.
Giles brings his own compelling narrative to ONE Fight Night 38, as he emerges from retirement following a 2022 departure from competition. The Australian veteran’s decision to return specifically for this matchup illustrates the respect both competitors share and the magnitude of their encounter. Their generational clash will be remembered for years by grappling fans fortunate enough to witness two masters performing their craft on the global stage.
Atomweight Kickboxing Queen Returns to Muay Thai Roots in ONE Fight Night 38
ONE Atomweight Kickboxing World Champion Phetjeeja begins her ambitious two-sport championship quest when she returns to Muay Thai competition against in-form Polish challenger Martyna Dominczak at ONE Fight Night 38. The 23-year-old Thai star brings an astounding 209 career victories into this atomweight Muay Thai scrap, showcasing the championship experience gained through years of competing at the highest levels.
“The Queen” captured four consecutive Muay Thai victories following her promotional debut in March before transitioning to kickboxing, where she defeated the legendary Anissa Meksen, former two-sport queen Janet Todd, and former K-1 champ Kana Morimoto while capturing the atomweight kickboxing throne.
Dominczak presents a dangerous test, as the Polish challenger rides momentum from recent strong performances. The European contender’s opportunity to derail one of ONE Championship’s brightest superstars adds intrigue to Phetjeeja’s two-sport ambitions.
