Both sides have agreed to the matchup, which was originally scheduled for UFC 256 on Dec. 12, but Yan was forced to withdraw then. The UFC has not announced a location for the UFC 259 pay-per-view event. MMAJunkie first reported the new date.
Yan (15-1) won the title in July, by defeating former featherweight champion Jose Aldo via TKO at UFC 251. Fighting out of Siberia, Yan has been perfect in the UFC. He holds a record of 7-0 in the Octagon, with wins over Jimmie Rivera, Urijah Faber and Aldo.
Yan is currently in Florida, to prepare for the fight at American Top Team in Coconut Creek.
Sterling (19-3), of New York, will ride a five-fight win streak into his first UFC title shot. The 31-year-old former collegiate wrestler has hit his stride in recent years, earning convincing wins over the likes of Rivera, Pedro Munhoz and Cory Sandhagen. He was the clear No. 1 contender in June, after submitting Sandhagen via rear-naked choke less than two minutes into the fight.
