UFC strawweight Mackenzie Dern weighed in at 123 lbs at the official weigh-ins for UFC 224 in Rio de Janeiro, Brazil. Her goal was to make 116 lbs; the limit for non-title strawweight fights.
Dern, who is 6-0 as a pro, made her UFC debut just two months ago. In that fight, at UFC 222, she beat Ashley Yoder via split decision. That bout was contested at strawweight and Dern did make weight (116 lbs).
Dern’s past struggles with weight cuts are well documented. Prior to the UFC she competed in a flyweight (125 lbs) and catchweight bout (120 lbs).
