The main event will see lightweight king Christian ‘The Warrior’ Lee move up in weight to challenge ONE Welterweight World Champion Kiamrian Abbasov. Meanwhile, in the co-main event, Thai megastar Rodtang Jitmuangnon will put his ONE Flyweight Muay Thai World Title on the line against current strawweight Muay Thai king Joseph Lasiri.

Lee and Lasiri are both looking for two-division glory against two of ONE’s most dangerous champions. Fans surely won’t want to miss a second of the action.

#2 Sambo Vs. BJJ Rivalry Continues

ONE Championship is rapidly expanding its roster of elite ground fighters. To that end, Brazilian Jiu-Jitsu star Danielle Kelly hopes to become the face of the promotion’s women’s submission grappling divisions.

First, though, she’ll need to get past four-time Sambo World Champion Mariia Molchanova. Their battle represents another intriguing chapter in the budding rivalry between sambo and BJJ that’s currently playing out in ONE.

Promotional newcomer Molchanova hopes to notch the first win for the Russian martial art. However, she’ll face an uphill battle against Kelly, who impressed in March at ONE X with a dominant, bonus-winning performance against MMA legend Mei Yamaguchi.

#3 A Longtime Champion Returns

The card also features the return of 11-time ONE Bantamweight World Champion Bibiano Fernandes, who aims to prove that he is still the elite fighter that ruled his division for nearly a decade.

Now 42 years old, ‘The Flash’ will lean on his veteran savvy, explosive striking, and top-of-the-food-chain grappling when he squares off with surging Filipino knockout artist Stephen Loman.
