Kamaru Usman vs. Jorge Masvidal and Alexander Volkanovski vs. Max Holloway are the main attractions on Saturday at UFC 251, but the undercard features plenty of other noteworthy fights.
Petr Yan and Jose Aldo will duke it out for the bantamweight title, while former champion Rose Namajunas is also back in action.
Henry Cejudo's abrupt retirement from the sport has left the division without a champion. Aldo comes in as the elder statesman with a storied career at featherweight and looking to add to his mantel. Yan will play the role of rising star with a ton of momentum behind him.
