Knockouts are a widely expected element of mixed martial arts. Similar to NASCAR fans watching in hopes of seeing a crash, many UFC fans watch solely for the purpose of watching knockouts.
Rarely does any fighter score a knockout on himself. But it happens.
Let's take a look at three of the best examples.
In the video above, you'll find former lightweight title challenge Gray Maynard talking about knocking himself out in a finale fighter against Rob Emerson. Although he still denies losing consciousness, Maynard went limp after scooping up Emerson for a double leg takedown and piledriving himself into the canvas.
The fight was scored a No Contest, as the slam aggrevated a rib injury from Emerson, who tapped out once he hit the mat.
Matt Lindland wasn't lucky enough to see a NC. When he attempted to slam Falaniko Vitale at UFC 43, the Oregonian wrestler landed on the back of his head, and went limp in the process. The embarrassing loss was only the second in his budding career.
He would get a rematch with Vitale and avenge the loss with a third round stoppage.
In the most notorious self-knockout in UFC history, Kevin Randleman didn't even get to step into the cage. Originally scheduled to face Pedro Rizzo at UFC 21, Randleman was scheduled to defend the UFC Heavyweight championship for the first time. Unfortunately for fans, Randleman would slip during warm-ups, and knock himself unconscious on the concrete floor.
The fight would eventually take place at UFC 26, with Randleman winning a decision.
