Alex Pereira and Raquel Pennington put their championships on the line Saturday in Salt Lake City.

The main and co-main event of UFC 307 are set to go with Pereira (205) and Pennington (135) both successfully making weight for their respective title defenses at Friday’s official weigh-ins. Pereira faces Khalil Rountree Jr., who also weighed in at 205 pounds, and Pennington takes on Julianna Peña in a long-awaited grudge match. Peña stepped to the scale at 134.5 pounds.

See weigh-in video for the top-2 fights below.

Possibly awaiting the winner of the bantamweight title fight is former PFL star Kayla Harrison, who weighed in at 136 pounds for her main card bout against Ketlen Vieira (136). After starting her career in the lightweight division, Harrison has now successfully hit the bantamweight mark twice, though both times she has used the one-pound allowance for a non-title fight.

Should Harrison defeat Vieira and earn a title shot, she will need to make 135 pounds or lower to be eligible for a championship opportunity.

All 24 fighters competing on Saturday’s card at Delta Center in Salt Lake City successfully made weight, including two-time strawweight champion Carla Esparza who has announced she will retire following her fight with Tecia Pennington.
