It was billed as two cowboys ready to lock horns and put on a heck of a show, but Donald Cerrone made sure it didn’t even get out of the opening round.

After trading knees in the clinch and eating two rights to the jaw, Cerrone shot in and took Alex Oliveira down, landing in half guard. Cerrone quickly moved to full mount and with Alex’s arm secured, Donald locked in the mounted triangle. Oliveira tried to roll and get out of it, but Cerrone locked it in even deeper and forced the tap. The official time of the submission came at just 2:33.
