ONE Championship has reshuffled its lightweight title picture, moving the championship bout between featherweight king Tang Kai and challenger Shamil Gasanov to ONE Fight Night 43 on May 15.
Tang Kai enters the contest as the reigning champion carrying a 19-4 overall record, with an 8-1 mark inside the ONE Championship cage. His lone loss under the ONE banner underscores how dominant he has been in the promotion, and he arrives at Fight Night 43 having established himself as one of the most consistent performers on the roster.
Gasanov steps up as the challenger with a 16-1 overall record and a 6-1 run in ONE Championship. That single defeat aside, his trajectory within the promotion has been sharply upward, and his 6-1 mark represents a strong case for a title shot at 155 pounds.
Why it matters
