Mackenzie Dern has failed to make weight multiple times throughout her young MMA career. After joining the UFC in 2018 as a strawweight contender, Dern missed weight only in her second fight in the promotion.
The 27-year-old was set to face Amanda Cooper at UFC 224, but she exceeded the weight limit by a massive seven pounds. After hitting the scales, Dern weighed in at 123 pounds. Although she forfeited a hefty amount of her fight purse, Dern had something to cheer about as she dominantly submitted Cooper in the first round.
In 2017, Mackenzie Dern moved up a weight class to compete in the flyweight division. However, she switched back to strawweight a few months before making her UFC debut.
Following her horrendous weight cut at UFC 224, Dern stated that she was ashamed of how things played out for her, and assured that she will never miss weight again.
"I’m ashamed of that. I don’t want that to happen again... I think I need to get my diet right and the fact I was able to do it before, I thought I knew what I was doing. A lot of things have been happening. It’s not an excuse, missed flights and a lot of things happened and I just kept going and going," said Dern at the post-fight press conference.
