The knockout of the week goes back to 2007, when Rashad Evans was still a rising prospect. His game was still so raw that he hadn't shown much in the kicking department. Unfortunately for Sean Salmon, Evans pulled out a head kick at the exact right time. Five years later, Evans will get another shot at the UFC light heavyweight belt on Apr. 21 against Jon Jones. Will he be able to pull out another knockout? Tell us in the comments, on Twitter or Facebook .
