UFC Vegas 101 weigh-in video

The UFC Vegas 101 weigh-in video features 28 fighters stepping on the scale Friday morning in Las Vegas. Watch official weigh-in highlights above, courtesy of UFC.

In the main event, Amanda Ribas looks to make it 2-0 against perennial contender Mackenzie Dern, and both women need to hit the strawweight limit of 116 pounds for a non-title fight. Ribas was victorious via unanimous decision in their first meeting in October 2019, and enters the fight looking to bounce back from a decision loss to Rose Namajunas in the flyweight main event of UFC Vegas 89 this past March.

Dern got back in the win column, and snapped a two-fight skid, with a decision win against Loopy Godinez at UFC Abu Dhabi this past October.

Santiago Ponzinibbio and Carlston Harris must hit the welterweight limit of 171 pounds for the penultimate bout of the card.

The official weigh-ins are expected to begin Friday at 12 p.m. ET / 9 a.m. PT.
