ONE Championship has reshuffled its lightweight title calendar, moving the championship bout between Tang Kai and Shamil Gasanov to May 15 as part of ONE Fight Night 43.
The organization confirmed the date change without offering a reason, though both fighters remain locked into the matchup. Only the timing has shifted.
Tang Kai enters the contest with an overall professional record of 19-4 and has been one of the most consistent performers on the ONE roster, compiling an 8-1 mark inside the promotion. The Chinese lightweight has built a reputation as a technically sharp striker with legitimate finishing ability across his career.
Shamil Gasanov brings a record of 16-1 overall and sits at 6-1 in ONE Championship. The Russian fighter has demonstrated a well-rounded skill set that blends grappling credentials with striking, and his lone promotional loss has done little to diminish his standing as a genuine title contender.
Why it matters
- The ONE lightweight title is on the line, making this one of the promotion's marquee divisional matchups
- Both fighters arrive with strong ONE records, meaning little separates them on paper heading into the rescheduled date
- ONE Fight Night 43 now carries added weight as a championship card with a confirmed main event
