Five rounds for the rematch!

The two fighters last met in July 2019 on the preliminary card of UFC on ESPN: dos Anjos vs. Edwards. Aldana started off on the front foot in the first round but Pennington pulled it back in the next two frames to ultimately win the tight contest via split decision.

Both fighters have only lost once since their 2019 bout, but Pennington has enjoyed a stronger record lately with an additional win and a five-fight win streak. She last lost a fight in January 2020 against Holly Holm at UFC 246.

Aldana, on the other hand, has lost one of her last five fights. Notably, her loss also came at the hands of Holm. The Mexican is coming off a splendid knockout win against Macy Chiasson, an upkick to the body that also won her the Performance of the Night bonus.
