UFC 273 will feature a championship doubleheader at the top of the card.
Alexander Volkanovski will defend his featherweight crown against Chan Sung Jung, while Aljamain Sterling and Petr Yan will meet in a bantamweight title rematch on April 9 at an as yet to be determined location. Ariel Helwani was first to report the UFC 273 title bouts.
Volkanovski was initially slated to face Max Holloway in a trilogy bout at UFC 272 on March 5, but the Hawaiian was forced to pull out of the fight with an undisclosed injury.
