Just when it looked like the writing was on the wall, Leon Edwards shocked the world and did the seemingly unthinkable.
In the UFC 278 main event Saturday at Vivint Arena in Salt Lake City, Edwards (20-3 MMA, 12-2 UFC) knocked then-reigning welterweight champion Kamaru Usman (20-2 MMA, 15-1 UFC) unconscious with a hail Mary head kick at 4:04 of Round 5.
The knockout blow came after nearly four rounds of relative domination by the champion Usman, who stifled Edwards with strong cardio, grappling, and control. Edwards looked noticeably frustrated at times, but ultimately scored the result he wanted in all-time fashion.
