ONE Championship has rescheduled its lightweight title fight between Tang Kai and Shamil Gasanov, moving the bout to May 15 at ONE Fight Night 43. The promotion did not offer a reason for the date change in its announcement.
Tang Kai enters the contest carrying a 19-4 overall record with an 8-1 mark inside ONE Championship, making him one of the more accomplished fighters in the organization's lightweight division. His lone ONE loss stands as the only blemish on an otherwise dominant run through the promotion.
Gasanov brings an even cleaner slate to the cage, sitting at 16-1 overall and 6-1 in ONE Championship. The single career loss across his entire professional career underscores how elite a prospect he has become at 155 pounds, and his ONE record reflects a similarly steady climb toward this title opportunity.
Why it matters
- The bout crowns a new ONE Championship lightweight champion, giving the division a clear titleholder going forward.
- Both men arrive with near-flawless records, meaning the loser absorbs only their second or second-to-last professional defeat, raising the competitive stakes considerably.
- With Tang Kai's organizational experience against Gasanov's unblemished overall ledger, the matchup pits proven ONE consistency against an unmatched outside résumé.
