The Californian is on a three-fight skid, including back-to-back first-round submission losses to Deiveson Figueiredo and Alexandre Pantoja, followed by a recent unanimous decision loss to Muhammad Mokaev in March. Perez is set to make a quick turnaround for this fight on Saturday.

Austen Lane (12-4-1NC)

Austen Lane's UFC debut last June ended in a no-contest due to an accidental eye poke.

David Onama (11-2)

David Onama dropped a majority decision to Nate Landwehr in a savage battle back in August 2022 but rebounded with a knockout win over Gabriel Santos last June. 'Silent Assassin' will hope to keep the momentum going when he returns to the octagon this Saturday.
