You don't often get knockout of the year contenders from the amateur ranks but this finish by American youngster Ahmad Jones is no ordinary KO.
Jones, who says he's been boxing for only one year and was in just his third fight, absolutely destroyed this opponent with the most savage of blows.
As his overmatched rival opened himself up to throw a one-two, Jones fired a heavy right hand straight down the middle. It knocked his opponent unconscious, but Jones wasn't finished, landing a heavy one-two to the already starched man in front of him.
Jones' rival wasn't helped by the referee, who was positioned too far across the other side of the ring and was a little slow off the mark when he moved to intervene. But he would have had to have been Usain Bolt to intercept those final punches.
