The UFC Vegas 107 weigh-ins ended on a troubled note as Maycee Barber failed to make weight for her fight against Erin Blanchfield. Barber weighed in at 126.5 pounds, exceeding the flyweight limit despite the one-pound allowance for non-title fights, while Blanchfield hit the target at 125 pounds. The fight is set to proceed at a catchweight, with Barber forfeiting 20 percent of her purse as a penalty, according to UFC officials confirmed by MMA Fighting’s Mike Heck.
Implications for championship hopes amid weight miss
Blanchfield and Barber were expected to headline the event from UFC APEX in Las Vegas, both ranked as top contenders, positioned at No. 4 and No. 7 respectively in the MMA Fighting Global Rankings. However, Barber’s failure to make weight could have negative consequences on her title aspirations, regardless of the fight’s outcome. The weigh-in difficulties have cast a shadow over what was anticipated to be a key matchup for the flyweight division’s future challengers.
Additional weigh-in issues and fight cancellation on the card
Aside from Barber, Allan Nascimento also missed weight, coming in at 127.5 pounds for his flyweight bout, 1.5 pounds over the limit. Moreover, a 180-pound catchweight matchup between Trevin Giles and Andreas Gustafsson was canceled due to Giles’ injury. Giles had accepted the fight on short notice, stepping in for Jeremiah Wells with less than a week to prepare.
