The MMA world reeled when Maycee Barber misses weight for her highly anticipated UFC Vegas 107 main event against Erin Blanchfield. On May 30, 2025, Barber tipped the scales at 126.5 pounds, a half-pound over the non-title flyweight limit, casting a shadow over a fight that promised title implications. The weigh-in miss, followed by the fight’s cancellation due to a potential seizure, sent shockwaves through fans and analysts. This blog dives into the latest developments surrounding Barber’s weight miss, its impact on her career, and what it means for the flyweight division.
The Weight Miss That Rocked UFC Vegas 107
Maycee Barber misses weight for the first time in her UFC career, a surprising stumble for the fighter known as “The Future.” At 126.5 pounds, she exceeded the 126-pound limit for her clash with No. 4-ranked Erin Blanchfield, who hit the mark at 125 pounds. Barber, ranked No. 7, faced immediate consequences, forfeiting 20% of her purse to Blanchfield. The fight was set to proceed as a catchweight bout, but the Nevada State Athletic Commission halted further weight-cutting attempts, citing health concerns. Fans noted Barber’s gaunt appearance at the weigh-ins, with some describing her as looking “cooked” or like she was “about to pass out.” Her intense stare and visible struggle sparked concern about her health even before the fight was canceled.
The weigh-in drama wasn’t isolated to Barber. Allan Nascimento also missed weight at 127.5 pounds for his preliminary bout, and Ketlen Vieira’s bantamweight fight with Macy Chiasson shifted to featherweight due to Vieira’s weight issues. Another fight, Trevin Giles vs. Andreas Gustafsson, was scrapped due to injury, leaving UFC Vegas 107 with a reshuffled 10-fight card. Barber’s miss, however, stole the spotlight, given the main event’s stakes.
Maycee Barber Misses Weight, Then Faces Health Crisis
Tragically, the story took a darker turn on fight night, May 31, 2025. Just minutes before the main event, UFC Vegas 107 lost its headliner when Barber was deemed unfit to compete due to a “last-minute medical issue.” Reports indicate Barber suffered a potential seizure, a devastating blow that led to her withdrawal. ESPN broadcasters announced the cancellation after airing a pre-fight feature, leaving fans stunned. Erin Blanchfield later shared that UFC executive Hunter Campbell informed her of Barber’s seizure, though official medical details remain sparse.
Barber’s health history adds context to this incident. After her last fight at UFC 299 in March 2024, she spent nine days in the hospital battling an illness, possibly linked to the Epstein-Barr virus. This led to her withdrawal from a UFC Denver main event against Rose Namajunas in July 2024. Her 14-month layoff and ongoing health challenges raised questions about her readiness for UFC Vegas 107. The potential seizure now puts her immediate fighting future in doubt, with fans and analysts urging caution and recovery over a quick return.
Impact on Barber’s Career and the Flyweight Division
When Maycee Barber misses weight, it’s more than a minor hiccup—it’s a setback for a fighter eyeing a title shot. A win over Blanchfield could have positioned her as a top contender against champion Valentina Shevchenko, who was cageside for the event. Instead, the weight miss and subsequent cancellation may stall her momentum. The flyweight division, already thin on contenders, now faces uncertainty. Blanchfield, who made weight and was ready to fight, emerges as the more favorable contender in the eyes of fans and matchmakers. Her professionalism contrasts with Barber’s struggles, potentially boosting her case for a title shot.
The division’s landscape remains competitive, with names like Natalia Silva and Manon Fiorot in the mix. However, Barber’s health concerns and weight miss could push her down the rankings, especially if the UFC opts to “ice” her as some fans speculated online. Her trash-talking during fight week, calling Blanchfield “one-dimensional,” now feels hollow given the outcome. For Barber, recovery and addressing her health issues will be critical before she can reclaim her trajectory toward the belt.
What’s Next for Maycee Barber?
The road ahead for Barber is uncertain. The potential seizure raises serious questions about her ability to compete at the elite level without addressing underlying health issues. Fans expressed disappointment online, with some calling her weight miss a “joke” and others sympathizing with her visible distress. The UFC’s decision to cancel the fight prioritizes fighter safety, but it leaves Barber’s career at a crossroads. Will she take time to recover, or will she push for a quick comeback to salvage her title aspirations?
For now, the focus shifts to Blanchfield, who may face a new opponent to maintain her momentum. The UFC could rebook Barber vs. Blanchfield once Barber is cleared, but her health must come first. Fans are left wondering if “The Future” can overcome this setback or if this marks a turning point in her promising career.
