On the June 23, 2008 episode of "Raw", Punk was drafted to the Raw brand during the 2008 WWE Draft. During his first night on "Raw", Batista beat down the World Heavyweight Champion Edge and left him lying in the ring. Punk then ran down the ramp to the ring with referee Mike Chioda. He then cashed in his Money in the Bank contract, hit Edge with the Go to Sleep and pinned him to become the new World Heavyweight Champion. Punk defended the title for the first time later in the night against JBL. Punk was able to hold the championship until Unforgiven on September 7, 2008. Before Punk was able to compete in the Championship Scramble match, he was attacked by The Legacy (Randy Orton, Cody Rhodes and Ted DiBiase with Manu). Orton ended the attack by punting Punk in the head. This led to Punk being unable to compete in the match and having to forfeit the title. In the match, Punk was replaced by Chris Jericho, who was able to win the match and the title. Punk had a rematch against Jericho eight days later on the September 15 episode of "Raw" but he was unable to regain the title in a steel cage match.
