Penn knocked Stevenson down seconds into the first round with a right uppercut, then took Stevenson down, delivering a well placed elbow from the top position that inflicted a serious cut near Stevenson's hairline. In the second round, Stevenson fought more aggressively but was still unable to threaten Penn. Penn worked to back mount and defeated him by rear naked choke at 4:02 of the second round to win the Lightweight Championship. He celebrated the win by licking Joe Stevenson's blood off of his gloves. The win for Penn was awarded Beatdown of the Year by Sherdog for 2008. With this win, Penn became the second man (after Randy Couture) to win UFC titles in two different weight classes.
