The UFC kicks off its October schedule Saturday with an ESPN card that features and Irene Aldana in women's bantamweight action in the main event.
Holm is looking to notch back-to-back wins for the first time since 2015 when she extended her undefeated streak and took the belt from Ronda Rousey. She scored a decision win over Raquel Pennington in her last bout.
While Holm has been fighting elite competition since the day she became champion, Irene Aldana is just now breaking into the top tier of the division.
She has won five of her last six bouts going back to 2018, including a first-round knockout of Ketlen Vieira in her last appearance.
