According to her head coach, Cody Donovan, Barber wanted to carry on with her flyweight bout against Erin Blanchfield this past Saturday at the UFC Apex in Las Vegas. However, the fight was canceled minutes before it was supposed to happen, something rarely seen before in the UFC, as her team didn't see her fit to compete that night.

Barber suffered a medical emergency just moments before her planned ring walk, meaning her bout with Erin Blanchfield was scrapped

What started as a typical introduction to a UFC main event ended in unprecedented and concerning fashion. On Saturday, the usual video package preceding the main event walkouts aired. But the walkouts never happened.
