Petr Yan vs. Aljamain Sterling bantamweight title fight working to be finalized for UFC 256

The UFC is working to finalize a bantamweight title fight between defending champion Petr Yan and Aljamain Sterling for UFC 256 on Dec. 12, according to UFC president Dana White.

Additional sources told ESPN that contracts have not been signed but the UFC is working to book the fight. Once official, the 135-pound title fight will serve as the co-main event at UFC 256, which will take place at the UFC's Apex facility in Las Vegas. A female featherweight bout between Amanda Nunes (20-4) and Megan Anderson (10-4) will headline.

Yan (15-1) won the UFC's vacant title in July by knocking out Jose Aldo in the fifth round of a title fight at UFC 251. The title was vacated earlier this year by double champion Henry Cejudo, who had announced his retirement. Yan, of Russia, is 7-0 in the UFC with four finishes.

Sterling (19-3) has been on an absolute tear since he suffered a first-round knockout loss to former champion Marlon Moraes in December 2017. Since then, he is 5-0 with wins over Brett Johns, Cody Stamann, Jimmie Rivera, Pedro Munhoz and Cory Sandhagen.

UFC 256 will be the UFC's final pay-per-view event of the year. The final event of 2020 will come one week later, a UFC Fight Night event on Dec. 19. White has already said he wants welterweight and middleweight phenom Khamzat Chimaev to headline that card against an opponent to be determined.
