April 10 in Bangkok just got a significant reshuffle — and both cards are better for it.
The vacant ONE Lightweight Kickboxing World Championship bout between Regian “The Immortal” Eersel and Rungrawee “Legatron” Sitsongpeenong has moved from ONE Fight Night 42 on Prime Video to headline The Inner Circle, streaming live at live.onefc.com in Asia primetime from Lumpinee Stadium.

In its place, the welterweight MMA collision between undefeated standouts Chase “Mannimal” Mann and Dzhabir Dzhabrailov steps up to top the Prime Video card in U.S. primetime.
The ONE World Title fight remains one of the most compelling matchups on either card. Eersel carries a 64-5 striking record and a 13-1 promotional mark into his bid to reclaim the lightweight kickboxing gold he once held — a title he won alongside the ONE Lightweight Muay Thai World Title to become a rare two-sport ONE World Champion.
The 6-foot-2 Surinamese-Dutch kickboxer is on a three-fight winning streak and returns with the specific purpose of reclaiming what he considers his.
Rungrawee, however, has earned this shot on pure merit. The Thai striker known for his devastating leg kicks carries a 158-48 career record and a 6-2 promotional mark, including a unanimous decision win over Youssef Assouik last August. He has wanted this title fight for some time, and he arrives at Lumpinee fully intending to leave as champion.

On the Prime Video side, Mann vs. Dzhabrailov is a fight with real consequences. Both men are undefeated, both finish fights, and both are operating in a welterweight division where the next title challenger to face Christian Lee could emerge from exactly this kind of matchup.
Mann is 7-0 with five finishes and made an immediate impression on his ONE debut earlier this year. Dzhabrailov is 6-0 with all six wins by finish, and has demolished all three of his ONE opponents inside two minutes. One of these records ends on April 10.
ONE Fight Night 42 on Prime Video and The Inner Circle both go down at Lumpinee Stadium on Friday, April 10.
