If you blink watching this video you just might miss the killer knockout that starts this Karate match. Over the years I seen a number of knocks some that come quick and some that happen late in a fight but this just might be the fastest one I have ever seen.

The official starts the match and in just three seconds it is all over with a roundhouse kick. This guy was out before he hit the mat and the few minutes it took to revive him he will never get back. The good part is with this on video when he asked what happened they can just show him the three seconds.
