ONE Championship has reshuffled its lightweight title picture, moving the featherweight gold clash between champion Tang Kai and top contender Shamil Gasanov to ONE Fight Night 43 on May 15.
The bout was previously slated for an earlier date, though the organization did not disclose the reason behind the change. The championship matchup remains intact, with only the event placement shifting.
Tang Kai enters as the reigning ONE lightweight champion carrying a professional record of 19-4 overall and an impressive 8-1 mark inside the ONE Championship cage. The Chinese standout has established himself as one of the most dominant fighters in the division, and this bout represents another opportunity to add a high-profile defense to his reign.
Gasanov arrives as one of the most compelling challengers in the weight class. The Russian contender holds a 16-1 professional record and has gone 6-1 under the ONE banner, with that single career loss underscoring just how rarely he has been beaten. His rise through the ONE rankings has been swift and decisive, earning him this shot at championship gold.
