Holly Holm finally has a date set for her highly anticipated UFC debut.

On Thursday, the UFC announced the former world champion boxer will meet The Ultimate Fighter 18 alum Raquel Pennington at UFC 181 in December.

Holm (7-0), a former boxing world champion who amassed a record of 33-2-3, has yet to taste defeat since making the switch to mixed martial arts in 2011. Since then she has laid waste to almost every single opponent thrown her way, securing violent knockouts in several different promotions. In her most recent outing, she earned the inaugural Legacy FC Women’s Bantamweight Championship with a violent headkick knockout over Juliana Werner in the main event of Legacy FC 30 in April.

“When I first started doing MMA, people asked me what my goal was in this, and my goal is to be the first female that has titles in both MMA and boxing because nobody’s done that,” Holm said after signing with the UFC in July. “And it’s totally doable, and that’s my plan.”

Raquel Pennington (4-4), a semifinalist on TUF 18, was last seen suffering a close split decision loss to Jéssica Andrade at UFC 171 in March. Prior to this loss ‘Rocky’ earned a unanimous decision victory in her UFC debut against women’s MMA pioneer Roxanne Modafferi at the TUF 18 Finale in November 2013.

UFC 181 is scheduled to take place at the Mandalay Bay Events Center on December 6. A welterweight title fight between Johny Hendricks and Robbie Lawler will serve as the night’s main event while a lightweight title fight between Anthony Pettis and Gilbert Melendez will serve as the co-main event.
