The UFC Vegas 107 weigh-in ended on a bad note after Maycee Barber didn’t make weight. This is the first time Barber has missed weight in her UFC career
A pivotal women’s flyweight matchup between Erin Blanchfield and Maycee Barber is set to headline Saturday’s card inside the UFC Apex in Las Vegas. This fight is important because both fighters are among the best.
This bout is more important to Barber as it marks her return to the octagon after her recent 14-month layoff due to health issues following her victory at UFC 299.
At the official weigh-ins that happened on the 30th of May, Barber registered at 126.5 pounds half a pound over—even including the one-pound allowance for a non-title fight. Blanchfield her opponent on the other hand successfully came in on point at 125 pounds

With this new development, it was confirmed by Mike Heck with UFC officials that Consequently, Barber will forfeit 20% of her purse to Blanchfield as her penalty and the fight will proceed as a catchweight bout.
The other main card fighters had no problems making weight. However, Barber wasn’t the only one on the UFC Vegas 107 card who missed weight.
Preliminary fighter Allan Nascimento weighed in at 127.5 pounds, which was over the flyweight limit, and one bout cancellation was announced Friday morning with Trevin Giles pulling out of a 180-pound catchweight bout against Andreas Gustafsson due to injury.
Giles stepped in on short notice—less than a week—as a replacement for Jeremiah Wells. It was a last-minute change that added even more drama to the card.
