Shadow Singha Mawynn refuses to let momentum fade, stepping into the biggest opportunity of his career when Tawanchai PK Saenchai’s injury opened the door for a featherweight kickboxing clash against Liu Mengyang at ONE Friday Fights 126.
The Thai destroyer will face “Spirit Dragon” Liu on Friday, September 26, inside Bangkok’s legendary Lumpinee Stadium, riding the confidence of his spectacular spinning backfist knockout over #2-ranked Bampara Kouyate just days ago at ONE Fight Night 35.

Tawanchai’s withdrawal due to injury created unexpected opportunity for Shadow to test his skills across disciplines. The ONE Featherweight Muay Thai World Champion in Tawanchai was originally scheduled to kick-start his charge back toward kickboxing gold against the dangerous Chinese striker.
Shadow’s rapid ascent from promotional debut disappointment to this moment represents one of combat sports’ most compelling redemption stories. After falling in his February 2024 introduction to ONE, the 25-year-old phenom rattled off five consecutive victories that earned him a six-figure contract.
His impressive run included statement victories over former ONE World Title challenger Jimmy Vienot and multi-time titleholder Sitthichai Sitsongpeenong, proving his ability to handle elite competition under maximum pressure.
The Kouyate knockout elevated Shadow’s profile to new heights while positioning him as legitimate title threat in the loaded featherweight division. Now he faces the challenge of translating Muay Thai success into kickboxing excellence against proven competition.

Liu represents the perfect test for Shadow’s cross-discipline ambitions. The 22-year-old Chinese striker shocked the global audience in his December promotional debut by defeating future ONE Interim Featherweight Kickboxing World Champion Masaaki Noiri via unanimous decision.
That breakthrough performance established Liu as serious contender before his split-decision loss to Iranian hard-hitter Mohammad Siasarani in April.
Liu enters this collision motivated to prove that his debut victory over Noiri wasn’t beginner’s luck while demonstrating superior kickboxing credentials against the surging Thai star.
