Maycee Barber's UFC Vegas 107 main event against Erin Blanchfield was canceled at the last minute due to Barber's undisclosed medical issue, possibly a seizure. Barber apologized to the UFC and Blanchfield via Instagram, stating her life isn't 'messy' despite Blanchfield's criticism. Barber, who missed weight by 0.5 pounds, has faced health problems and a 14-month Octagon absence. The fight cancellation follows a previous postponement due to Barber's injury.
