UFC 278 went down on Saturday in Salt Lake City, and it was one for the books.
In the main event, Leon Edwards ushered in a new era at welterweight, swiping the division's title from dominating champion Kamaru Usman with a stunning fifth-round head kick. It was a substantial upset, made more impressive by the fact that Edwards was less than a minute removed from what would have been a lopsided decision loss.
In the co-main event, former middleweight champ Luke Rockhold returned from a long absence, taking on dangerous Brazilian contender Paulo Costa. Rockhold gave a gusty effort but was ultimately outfought to a bloody unanimous-decision loss.
