ONE Championship has officially rescheduled its lightweight title fight between champion Tang Kai and top contender Shamil Gasanov, moving the bout to May 15 at ONE Fight Night 43. The promotion announced the date change without providing a reason for the shift.
Tang Kai enters the bout as the reigning ONE lightweight champion, carrying an overall record of 19-4 and an impressive 8-1 mark inside the promotion. The Chinese finisher has established himself as one of the most dangerous fighters in the division during his ONE tenure, and this defense represents another opportunity to cement his legacy at the top of the lightweight rankings.
Gasanov brings a record of 16-1 overall and 6-1 in ONE Championship, making him one of the most formidable challengers the promotion could place in front of its titleholder. The Dagestani fighter has moved steadily through the lightweight ranks, losing just once inside the promotion on his way to earning this title shot.
