Get ready, fight fans! The world’s largest martial arts organization will break new ground when it returns to the iconic Lumpinee Boxing Stadium in Bangkok, Thailand, with ONE Fight Night 17, which broadcasts live in U.S. primetime on Friday, December 8.

For the first time ever, ONE Championship is staging an all-Muay Thai card that is headlined by a historic World Title showdown of epic proportions.

In the main event, ONE Light Heavyweight Kickboxing World Champion Roman Kryklia aims to become a two-sport king and claim the inaugural ONE Heavyweight Muay Thai World Title.

But freshly minted WBC Heavyweight Muay Thai World Champion Alex Roberts wants to make an instant impact in his promotional debut and become the first person to defeat the 6-foot-7 Ukrainian superstar in ONE.

The all-striking lineup also features Thai powerhouse “Smokin” Jo Nattawut, American sensation Luke Lessei, 17-year-old Malaysian-American prodigy Johan Ghazali, and top-ranked bantamweight Muay Thai contenders Felipe Lobo and Saemapetch Fairtex.

So mark your calendar, put a reminder in your phone, and make sure you don’t miss ONE Championship’s final U.S. primetime blockbuster event of 2023!
