Check Out This 5 Second MMA Knockout (Video)

5 second knockout

Got five seconds to spare?  If so, I suggest you use it to check out this five second MMA knockout from a Mayhem in Mesquite IV bout between Corey Conway and AJ Leone.

The knockout—which came via a mean overhand right from Conway—happens so fast that the two-minute round clock in the bottom right-hand corner didn’t even have a chance to start.

Check it out, but don’t blink, else you might miss it:
