Valentina Shevchenko and Julianna Pena will square off in the main event of UFC on FOX 23 this coming January.
Shevchenko (13-2) recently scored a win over former UFC female bantamweight champion Holly Holm, pushing her Octagon mark to 2-1 overall. Her only loss to date with the promotion came at the hands of current UFC titleholder Amanda Nunes.
Pena (8-2), a former winner of The Ultimate Fighter, has yet to taste defeat in four bouts with the UFC. That includes a summer victory over Cat Zingano.
UFC on FOX 23 takes place January 28 from the Pepsi Center in Denver. Along with Shevchenko-Pena, Hector Lombard battles Brad Tavares and J.C. Cottrell meets Jason Gonzalez.
