The UFC kicks off its 2025 in the one spot no one really wanted to see them – back at the Apex, this time for UFC Vegas 101.
That said, the understated Fight Night card was more appetizer than main course, with UFC 311 arriving in just a week. And with fans starved for fights for a few weeks (with the exception of RIZIN and Oktagon MMA), even an Apex card was a welcome return.
In the main event, a rematch years in the making as Mackenzie Dern looked to win one back over Amanda Ribas.
Weigh-ins for this Saturday’s UFC Vegas 101 card took place on Friday, January 10, 2025. Full results can be found below.
