The Octagon is back at the UFC Apex in Las Vegas after a couple of weeks away for tonight's UFC on ESPN+ 81 which closes out the promotion's month.

Mackenzie Dern and Angela Hill square off in a battle of ranked strawweights in the five-round main event. It will be Dern's third main event, but she's still in search of her first main event win following a loss to Yan Xiaonan in October. Hill is in her second main event as she looks to extend a two-fight win streak.

In the co-main event, it's a middleweight clash as Edmen Shahbazyan takes on Anthony Hernandez. The main card will feature a welterweight fight between Andre Fialho and Joaquin Buckley, as well as a battle of lightweight veterans when Diego Ferreira takes on Michael Johnson.
