A plethora of combat sports action returns to the forefront when ONE Championship takes over Lumpinee Boxing Stadium in Bangkok, Thailand, with ONE Fight Night 22: Sundell vs. Diachkova next month.
The action takes place on Saturday, 4 May, with a star-studded card across four fighting disciplines, ranging from world-class Muay Thai all the way to elite submission grappling and everything in between.

The main event sees the return of ONE Women's Strawweight Muay Thai World Champion Smilla Sundell, who defends her crown against dangerous contender Natalia Diachkova at the top of the billing.
Throughout her promotional tenure, Sundell has been unstoppable. The striking phenom has pieced up every opponent. And at only 19-years-old, it's clear to see that with every performance the Swedish striker is only getting better.
Unbeaten across four promotional outings, Sundell was at her absolute best last time around when ONE Women's Atomweight Muay Thai World Champion Allycia Hellen Rodrigues entered the Swede's weight bracket.
Sundell used her sheer size and striking skills to repeatedly hurt Rodrigues before scoring the most monumental finish of her career in the third round at ONE Fight Night 14 last September.
This time, her adversary poses just as much of a finishing threat as she does. Diachkova has amassed three knockouts in four promotional bouts, with her latest coming just last month at ONE Friday Fights 55.
The Russian wrecker's latest stoppage was so impressive that it earned her a direct opportunity to vie for the strawweight Muay Thai gold. And with her finishing potential, it makes for a potential barnburner at ONE Fight Night 22.
