With Maryna Moroz out, Montana De La Rosa steps in to face Taila Santos at UFC Fight Night on Dec. 5

Taila Santos will look to hit the flyweight rankings by vanquishing a new opponent.

Maryna Moroz has been forced to withdraw from UFC Fight Night on Dec. 5, and Montana De La Rosa will step in to face Santos (16-1 MMA, 1-1 UFC).

Combate reported the news Tuesday night. Two people with knowledge of the matchup confirmed the bout with MMA Junkie, but asked to remain anonymous since the promotion has yet to make an official announcement.

After suffering her first career loss to Mara Romero Borella in her UFC debut in February 2019, Contender Series graduate Santos rebounded with a unanimous decision win over the streaking Molly McCann at UFC on ESPN 13 in July.

De La Rosa (11-6 MMA, 4-2 UFC), who submitted her first three UFC opponents, has lost two of her past three, most recently a unanimous decision to Viviane Araujo at UFC on ESPN+ 34 in September.

With the change, the Dec. 5 lineup includes:

• Jack Hermansson vs. Kevin Holland
• Bethe Correia vs. Yanan Wu
• Jake Collier vs. Gian Villante
• Cody Durden vs. Jimmy Flick
• John Allan vs. Roman Dolidze
• Damon Jackson vs. Ilia Topuria
• Jamahal Hill vs. Ovince Saint Preux
• Raoni Barcelos vs. Merab Dvalishvili
• Movsar Evloev vs. Nate Landwehr
• Jose Quinonez vs. Louis Smolka
• Montana De La Rosa vs. Taila Santos
