At Pepsi Coliseum in Quebec City, Quebec, Lucian Bute (25-0, 20KOs) knocked out Librado Andrade (28-3, 21KOs) in four rounds to retain his IBF super middleweight title. Bute erased the drama from last October's controverial win over Andrade.

Bute was very cautious in the first round and tried to stay out of range while Andrade pushed forward. Bute seemed to box well from the distance. The second round played out in the same way but in the third round - Bute began to let his hands go and landed some big left hands to push Andrade back.

During the fourth round, they began to trade hard punches. Andrade walked into a left hand and went down on his face. He made it up and tried to trade punches at close range. A moment later Bute unloaded with a massive body shot to send Andrade down for the full count.
