Aliff Sor Dechapan Finally Gets His Shot At Prajanchai In Strawweight Muay Thai Unification Bout
Nearly a year after earning the right to face Prajanchai Pongsuphan PK, Aliff Sor Dechapan finally gets his chance. The ONE Interim Strawweight Muay Thai World Champion meets the reigning divisional king in a title unification bout at The Inner Circle 43 on Friday, December 18.
The five-round showdown takes place at Bangkok’s Lumpinee Stadium and streams live in Asia primetime exclusively for subscribers at live.onefc.com. Only one man will leave with undisputed strawweight Muay Thai gold.
Aliff first earned his title shot with a unanimous decision over Ramadan “The Scorpion” Ondash at ONE Fight Night 38 in December 2025. Months after his kickboxing rematch with Jonathan Di Bella at ONE Fight Night 36 in October 2025, however, Prajanchai suffered an injury that required surgery.
Rather than wait on the sidelines, the 22-year-old kept moving. In July at The Inner Circle 23, he knocked out the legendary Sam-A Gaiyanghadao in the fifth round to capture interim gold and become the first Malaysian to win a ONE World Title.
That performance earned him a US$50,000 bonus and a hero’s welcome at home, where Prime Minister Datuk Seri Anwar Ibrahim joined the celebrations. It also extended his winning streak to six and lifted his record to 63-9.
The Sor Dechapan representative uses his rangy frame to keep opponents at the end of his shots, chops at the body with his left kick, and waits patiently to counter. Six of his 10 promotional wins have come in highlight-reel fashion.
Prajanchai, meanwhile, has only just eased back into action. The 32-year-old PK Saenchai Muaythaigym star returned at The Inner Circle 35 in kickboxing and lost a razor-close split decision to “The Warrior” Wang Junguang.
That setback does little to dim a resume that includes 344 career wins and a reign as a two-sport ONE World Champion. During a six-fight tear, he outpointed Di Bella in their first kickboxing meeting and finished both Sam-A and Joseph Lasiri.
A sharp teep, an elite fight IQ, and an ability to read rhythm within moments have long made him the standard in this division. On December 18, a young Malaysian who has already rewritten history once gets his chance to prove that standard has changed.
