Their championship run came to an abrupt end after Kidman turned his back on London. The heel turn played off of a legitimate injury which occurred on an August 24, 2004 taping of "SmackDown!", when Kidman's shooting star press unintentionally caused Chavo Guerrero to suffer a concussion. The next week, Kidman was on the top rope ready to hit the shooting star press, but hesitated, climbed down the turnbuckles, and slowly walked backstage overwhelmed with guilt after injuring Guerrero. As a result, London and Kidman faced each other at No Mercy, where Kidman defeated London before performing the shooting star press on London while he was strapped to a stretcher. This completed Kidman's heel turn, as he proceeded to blame the fans for wanting him to be more brutal with his in-ring style. Kidman and Guerrero ended their feud upon Chavo's return, the latter being victorious in the final match. Kidman then competed against London over the Cruiserweight Championship in the coming months. At the start of 2005, Kidman suffered a broken orbital bone, which sidelined him for three months.
