The ONE Championship lightweight title fight between champion Tang Kai (19-4, 8-1 in ONE) and top contender Shamil Gasanov (16-1, 6-1 in ONE) has been rescheduled. The championship bout will now take place on May 15 at ONE Fight Night 43, rather than its originally planned date. Both fighters bring strong records into this matchup, with Tang Kai defending his title against the surging Gasanov. The reason for the date change was not specified in the announcement. This represents a significant fight in ONE's lightweight division, pitting the established champion against a dangerous challenger with only one career loss.
ONE Championship has officially moved its lightweight title fight between champion Tang Kai and top contender Shamil Gasanov to May 15, with the bout now set for ONE Fight Night 43. No reason was given for the rescheduling.
Tang Kai enters the contest as the reigning ONE lightweight champion, carrying a professional record of 19 wins and 4 losses, including an 8-1 mark inside the ONE Championship cage. His run under the ONE banner stands as one of the most impressive in the lightweight division, and he brings championship experience into this defense.
Gasanov arrives as one of the most dangerous challengers in the division. The surging contender holds a 16-1 professional record with a 6-1 mark in ONE, and his lone career loss remains a rare blemish on an otherwise dominant run. His momentum heading into this fight has made him a credible threat to unseat the champion.
Why it matters
- Tang Kai's title reign faces its latest and perhaps sternest test against a challenger with just one career loss
- Gasanov's 6-1 ONE record signals he has moved steadily through the divisional ranks toward this moment
- The outcome will shape the direction of the ONE lightweight division for the foreseeable future
- ONE Fight Night 43 on May 15 now carries added weight as a title-fight card
