ONE Championship returns to Lumpinee Stadium in Bangkok on Friday, May 29 (7:30 AM EDT) with a stacked double‑header: The Inner Circle followed immediately by ONE Friday Fights 156. The promotion is once again blending elite Muay Thai, kickboxing, and MMA talent, from established champions to hungry prospects fighting for a life‑changing US$100,000 contract.
The Inner Circle card opens the day with exclusive matchups featuring the Ondash brothers of Lebanon, while ONE Friday Fights 156 delivers a high‑stakes main event between Kongsuk Sitsarawatsuer and Khakimov Anisjon in a bantamweight Muay Thai showdown.
But for Korean fans, all eyes are on one man.
Spotlight: South Korea’s Seong Gyu Jang
While the official bout listings are still being finalized, Seong Gyu Jang is expected to represent South Korea on this card, a rising talent known for his grit, pressure, and ability to thrive in chaotic exchanges.
Jang is part of the new wave of Korean strikers making their mark at Lumpinee. He fights with a hybrid style: traditional Korean kickboxing fundamentals layered with the clinch toughness demanded by Thai stadium competition. He’s not the flashiest fighter. He’s the one who breaks opponents down piece by piece.
Who Is Seong Gyu Jang?
Jang built his name on the Korean domestic circuit before transitioning to the international stage. What makes him compelling is his adaptability, he’s not married to one rhythm or one weapon. He reads opponents, adjusts, and chips away until the fight bends in his direction.
He’s also part of a growing movement of Korean athletes who are embracing Thailand’s stadium system as a proving ground, sharpening their game against the world’s most seasoned strikers.
ONE Friday Fights Prediction: Seong Gyu Jang vs. Adilet Kalenderov
This matchup is a classic clash of styles:
Seong Gyu Jang
- Thrives in long exchanges
- Builds momentum as rounds progress
- Strong chin, strong gas tank
- Prefers to pressure and force mistakes
Adilet Kalenderov
- Typically explosive early
- Heavy hands and fast entries
- Dangerous in the first half of the fight
- Can struggle if forced backward
HanPunch Prediction
If Jang survives the early storm, the fight tilts heavily in his favor. Kalenderov’s power is real, but Jang’s durability and volume striking are built for longer battles. Expect Jang to take over in the second half with combinations, body work, and pace.
Prediction: Seong Gyu Jang by late-round surge or decision.
