Lumpinee Stadium giveth and Lumpinee Stadium taketh away. On December 19, it watched Tawanchai PK Saenchai collapse with a broken leg that would sideline him for up to a year. Now on Saturday, February 14, the venue will crown the interim champion who’ll keep the featherweight division moving.
Nico Carrillo faces Shadow Singha Mawynn for the ONE interim featherweight Muay Thai world title at ONE Fight Night 40 at Lumpinee Stadium in Bangkok. For Carrillo, it’s redemption. For Shadow, it’s validation.
The 27-year-old Scottish wrecking ball knows exactly what slipped away a year ago. Nabil Anane stopped him in the first round of their interim bantamweight title fight at ONE 170, ending Carrillo’s perfect promotional run and forcing a painful reassessment.
That loss clarified everything. Carrillo returned to featherweight — where his frame and power carry naturally — and looked unstoppable. He finished Thai legend Sitthichai Sitsongpeenong inside two rounds in April, then stopped Luke Lessei seven months later. Both by knockout. Both proving he belongs at 155 pounds chasing championship gold.
Shadow brings his own Lumpinee credentials. The Thai knockout artist arrived in ONE Championship as a Rajadamnern Stadium Muay Thai champion — the kind of Bangkok stadium validation that separates legitimate contenders from promotional hype. After a shaky start, he’s built an impressive win streak including victories over Jimmy Vienot, Mohammad Siasarani, and Sitthichai.
That Sitthichai connection creates natural intrigue. Both fighters defeated the legendary Thai striker, raising the stylistic question: Whose power translates better at Lumpinee with an interim title on the line?
The venue adds weight beyond location. Tawanchai’s injury happened here during ONE Friday Fights 137, when Liu Mengyang’s leg kick collapsed the champion in 52 seconds, albeit under kickboxing rules. Now Lumpinee decides who wears interim gold and faces Tawanchai upon his return.
February 14 also decides who gets redemption and who gets coronation. And Lumpinee Stadium — the center of Muay Thai’s universe — gets to decide which story gets written.
