Andy Lee Knocks Out John Jackson

Boxing fans were treated to a sensational one-punch knockout over the weekend. Andy Lee is a former middleweight world title challenger who dropped down to the light middleweight division to try and make another run at a title. He fought John Jackson at Madison Square Garden in New York City this weekend on the undercard of the middleweight showdown between Miguel Cotto and Sergio Martinez (a fight which Cotto dominated and won).

Lee, who was trained for several years by Emanuel Steward before his death and sparred frequently with Wladimr Klitschko during that time, is now trained by Adam Booth in London. The fight was not going well for him; he was knocked down in the first stanza and Jackson was all over him for four rounds. In the fifth, Jackson hurt Lee on the ropes, and just when it looked like the Virgin Islander might end the fight, this happened:

What a punch! Jackson had so much success with his overhand right all fight that he dropped his guard as he wound up to throw again. Lee, who told press that the right hook was a shot he and his trainer worked on in their training camp, timed his opponent perfectly and countered, and it was lights out for Jackson. Lee moves to 33-2, 23 KOs with this win, and Jackson drops to 18-2, 15 KOs.

Here is the shot again:
