A colossal lineup of martial arts action awaits the global fan base when ONE Championship returns to U.S. primetime airwaves on Friday, April 4, with ONE Fight Night 30: Kryklia vs. Knowles, which broadcasts live from Bangkok’s Lumpinee Stadium.

The card is headlined by two massive World Title showdowns.

In the main event, towering two-sport king Roman Kryklia defends the ONE Heavyweight Muay Thai World Title and seeks his fourth straight knockout victory. But his challenger, WBC Heavyweight Muay Thai World Champion Lyndon Knowles, has every intention of claiming the richest prize in the sport and ending Kryklia’s flawless run in ONE Championship.

Plus, another two-sport king in Regian Eersel puts his ONE Lightweight Kickboxing World Championship on the line against former titleholder Alexis Nicolas in a thrilling trilogy battle. The rivals are deadlocked 1-1 in their heart-pounding series, putting even more than 26 pounds of gold at stake.

More bouts will be announced in the weeks to come, so mark your calendar, put a reminder in your phone, grab your tickets, and make sure you don’t miss ONE Fight Night 30: Kryklia vs. Knowles live!
