Peña (5-2) had lost her two bouts leading up to her stint on the The Ultimate Fighter, but she more than made up for them by becoming Team Tate’s top pick and running the gambit on the reality show.
After winning four fights on the TV show, including the bout that gained her entry into the fighter house, Peña TKO’d world-champion boxer Jessica Rakoczy at the finale in November.
Andrade (10-3) didn’t make much of a splash in her Octagon debut, when she got TKO’d by former UFC title challenger Liz Carmouche in the second round in July. She bounced back strong, however, dominating Rosi Sexton in October.
UFC 171 is headlined by Johny Hendricks and Robbie Lawler in a battle for Georges St-Pierre’s vacated UFC welterweight championship.
