Two more bouts have been confirmed for ONE Fight Night 43: Tang vs. Gasanov, live in U.S. primetime from Bangkok’s Lumpinee Stadium on Friday, May 15.
ONE Flyweight Submission Grappling World Champion Diogo “Baby Shark” Reis steps up a division to strawweight to face Yuki Takahashi in a high-level grappling matchup that tests the Brazilian champion against a fresh challenge at a heavier weight class.

Reis has been a force since arriving in ONE Championship in March 2025, submitting Shoya Ishiguro via kimura on debut before capturing the flyweight submission grappling title with a victory over Daiki Yonekura in December.
The 24-year-old two-time ADCC World Champion carries a 94-9 career record into this bout and is seeking his third consecutive promotional win against his third Japanese grappling opponent.
Takahashi makes his ONE debut in the difficult position of facing a reigning world champion — a career-defining performance will be required to derail “Baby Shark’s” momentum from the outset.
The second addition brings former ONE Bantamweight Kickboxing World Champion Petchtanong Petchfergus back to the card against Ben “The Problem” Woolliss in bantamweight kickboxing action.

Petchtanong, 40, represents Superbon Training Camp and carries a 359-57 professional record and three ONE victories into this bout. His promotional wins include defeats of two former divisional kings in Hiroki Akimoto and Alaverdi “Babyface Killer” Ramazanov, giving him a well-earned reputation as a championship-level threat at 135 pounds.
Woolliss announced himself emphatically at ONE Fight Night 41 in March, stopping former ONE Bantamweight MMA World Champion John “Hands of Stone” Lineker via calf kick TKO in his debut.
The 31-year-old moves down a division with a 30-6 career record for this assignment, and a win over a former world champion would immediately establish him as a genuine force in the bantamweight kickboxing landscape.
