A must-see blockbuster spectacle awaits the global fan base, as the world’s largest martial arts organization returns to Bangkok’s Impact Arena for ONE 167: Tawanchai vs. Nattawut II. In the headline attraction, two of the most dangerous knockout artists on the planet meet in a high-stakes rematch – and the ONE Featherweight Muay Thai World Title is on the line. After edging out his compatriot in a nail-biting kickboxing war last October, reigning ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai is determined to finish #3-ranked contender “Smokin” Jo Nattawut under his preferred rule set and establish himself as the most dominant striker the division has ever seen. But Nattawut has the knockout power to end anyone’s night in the blink of an eye, and the Thai veteran is extra motivated to become the first man to put Tawanchai to sleep in ONE Championship and claim the richest prize in the sport. Also, after nine months away, longtime ONE Flyweight Muay Thai World Champion Rodtang Jitmuangnon will finally return to action. But welcoming him back inside the Circle will be Denis Puric, who has called “The Iron Man” out for years and has promised to “make a fool out of him.” Plus, ONE Lightweight Submission Grappling World Champion Kade Ruotolo makes his highly anticipated MMA debut, fellow submission grappling king Mikey Musumeci moves up a weight class to seek revenge against the last man to defeat him, and British superstar Liam Harrison and Malaysian wunderkind Johan Ghazali make their long-awaited returns.
