The Octagon is back inside the Fight Capital of the World this weekend as UFC on ESPN+ 97: Tuivasa vs. Tybura takes place at the UFC Apex in Las Vegas.

The main event is a five-round heavyweight bout pitting knockout artist and fan favorite Tai Tuivasa against long-time veteran Marcin Tybura. Both are looking to get back into the win column as Tuivasa is on a three-fight losing skid, while Tybura is trying to rebound from a loss to Tom Aspinall.

In the co-main event, former TUF winner Bryan Battle and Ange Loosa square off in a welterweight fight with both looking for their third straight win. Also on the main card is a light heavyweight bout between Ovince Saint Preux and Kennedy Nzechukwu; a battle of top-ten women's bantamweights as Pannie Kianzad takes on Macy Chiasson; and a middleweight fight between veterans Gerald Meerschaert and Bryan Barberena.
