A shocking medical emergency derailed the UFC Vegas 107 main event on June 21, 2026, when Maycee Barber suffered what was described to her opponent as a possible seizure, forcing officials to cancel the women's flyweight headliner just minutes before the fighters were set to walk out.
According to a Yahoo Sports report, UFC officials determined Barber was not medically cleared to compete, bringing an abrupt end to a bout that had been scheduled to go ahead as planned. The speed of the cancellation — happening in the final moments before walkouts — underscored the seriousness of the situation and left serious questions hanging over Barber's immediate future in the sport.
Barber, 28, is one of the most prominent fighters in the women's flyweight division. Fighting out of Team Alpha Male, the American holds a record of 15-3-0 and carries a divisional ranking of fourth. Known for her high-output offense, she lands 4.56 significant strikes per minute at a 53 percent accuracy rate, and supplements her striking with 1.56 takedowns per 15 minutes. The cancellation represents a significant setback for a fighter who had positioned herself near the top of a competitive 125-pound division.
