The UFC quickly found a replacement for injured TUF champion Julianna Pena.
Pena, who suffered a serious knee injury in training, has been replaced by TUF 18 teammate Raquel Pennington at UFC 171 on March 15. Pennington will now face Jessica Andrade in a bantamweight contest, according to UFC officials Wednesday.
Pennington (4-3) won her UFC debut this past November when she defeated Roxanne Modafferi via unanimous decision.
Andrade (10-3) is 1-1 in the UFC, defeated Rosi Sexton via unanimous decision at UFC Fight Night 32 and losing via second-round TKO to Liz Carmouche at UFC on FOX 8.
Johny Hendricks will face Robbie Lawler for the vacant UFC welterweight title in the main event.
