UFC 307 is set to go down at the Delta Center in Salt Lake City, Utah, on Saturday.
There will be two titles on the line. Light heavyweight champion Alex Pereira is set to try and defend his belt against Khalil Rountree Jr. Before that, bantamweight queen Raquel Pennington will look to keep her title against the challenging Julianna Pena, the former champion who once upset Amanda Nunes.
The rest of the main card is rounded out by former featherweight champion Jose Aldo taking on Mario Bautista at bantamweight, Kayla Harrison fighting Ketlen Vieira in a potential bantamweight title eliminator, and Roman Dolidze squaring off with Kevin Holland at middleweight.
