Highlight Video: Watch Diego Rivas Knock Noad Lahat Cold with Jumping Knee

Diego Rivas rallied from a disastrous opening round to knock Noad Lahat unconscious with a spectacular flying knee almost as soon as the second round began.

Lahat dominated Rivas in the first with takedowns and submission attempts, keeping the Chilean on the defensive for the opening five minutes. But just 23 seconds into the next frame, Rivas exploded with a flying knee that removed the Israeli from his consciousness.
