The Octagon is back inside the UFC Apex in Las Vegas for the final time in 2023 for UFC On ESPN+ 91: Song vs. Gutierrez.

The main event is a five-round battle of ranked bantamweights as Song Yadong takes on Chris Gutierrez, who is in his first UFC main event. Both men are looking to notch their second consecutive win as Song is coming off a win over Ricky Simon in April, while Gutierrez is coming off a win over Alatengheili in October.

In the co-main event, it is a light heavyweight battle as former title challenger Anthony Smith takes on Khalil Rountree. Also on the main card is a lightweight match-up between Nasrat Haqparast and Jamie Mullarkey, a bantamweight bout pitting Tim Elliott against Sumudaerji, and a middleweight bout between Jun Song Park and Andre Muniz.
