Brock finally received a shot at the world title, having agreed to face Wladimir Klitschko for IBF world heavyweight championship. The fight took place at Madison Square Garden on November 11, 2006. In the opening rounds, Brock's economical but effective movement made Klitschko reluctant to throw punches, with Wladimir not being able to fully establish his rhythm. In between the 3rd and 4th rounds, Klitschko's trainer Emmanuel Steward urged Wladimir to press the action. From the fourth round, Klitschko started fighting more aggressively, hurting Brock several times with the right cross. In the fifth round, Brock opened a cut under Klitschko's left eye that started bleeding heavily in the sixth. In round 7, Brock was caught with a counter right hand before being sent to the canvas with another straight right. Brock was able to get up but the referee stopped the bout, deciding that Brock appears to be unable to continue.
