UFC 273 on Saturday features two title bouts and a chance to see a rising star.

Alexander Volkanovski defends his UFC featherweight gold against Chan Sung Jung, whose name has practically been replaced by his Korean Zombie nickname. Though that is the main event, the most highly anticipated bout of the evening is the Aljamain Sterling-Petr Yan rematch, which will determine the undisputed bantamweight champion.

After Yan intentionally knocked out Sterling with an illegal knee in their last bout 13 months ago, 273 stands as redemption for Sterling, who wants to prove there is no better bantamweight in the world–and make Yan suffer in the cage. The juggernaut Khamzat Chimaev also seeks to continue his destruction, which will be an incredibly challenging task against perennial welterweight contender Gilbert Burns.
