Pennington was scheduled to face Holly Holm at UFC 181 on December 6, 2014. However, Holm pulled out of the fight in mid-November, citing a neck injury. Holm was replaced by UFC newcomer Ashlee Evans-Smith. Pennington won the fight via technical submission due to a bulldog choke at the end of the first round. She became the 4th fighter in UFC history to finish a fight with that move.
