Kamaru Usman looked well on his way to defending his welterweight title for the sixth time.
Until he wasn't.
Leon Edwards landed a shocking head kick in the final round to stun Usman in the UFC 278 main event. All the momentum was in the other corner before the kick after the champion scored multiple takedowns and was in full control.
UFC President Dana White went as far as to tell reporters Usman fought "the perfect fight" until everything changed.
"You think of everything that was on the line for Usman tonight, and Usman fought with absolute and total confidence all night," White said.
