ONE Championship has confirmed a new date for its lightweight title fight, with champion Tang Kai set to defend against Shamil Gasanov on May 15 at ONE Fight Night 43.
The promotion announced the rescheduling without offering any explanation for the postponement. Both fighters remain locked in for the bout, which carries the ONE lightweight championship on the line.
Tang Kai enters the fight carrying an overall professional record of 19-4 and has gone 8-1 inside the ONE Championship cage. The Chinese striker has established himself as one of the most dangerous lightweights in the promotion and holds the title heading into this defense.
Gasanov represents a significant threat to that reign. The challenger owns a 16-1 professional record with a 6-1 mark in ONE competition, making him one of the more accomplished lightweights on the roster. His lone ONE loss has done little to slow his momentum, and he arrives as a genuine contender for the belt.
Why it matters
- The ONE lightweight title is at stake, with the division's hierarchy determined by the outcome
- Tang Kai's strong 8-1 ONE record will be tested against a challenger who has lost just once in the promotion
- Gasanov's 6-1 ONE mark reflects a rapid rise through a competitive lightweight division
- A change in champion would reshape the entire ONE lightweight landscape
