In August 2003, Nash feuded with Chris Jericho and was forced to cut his hair after losing a hair vs. hair match against Jericho on the August 18 episode of "Raw". This was made to cover for Nash having to cut his hair for his role as "The Russian" for the 2004 "Punisher" film. His last match in WWE was at SummerSlam in an Elimination Chamber match for the World Heavyweight Championship against Triple H, Shawn Michaels, Goldberg, Chris Jericho, and Randy Orton. He was the first to be eliminated after Jericho pinned him following Sweet Chin Music from Michaels. Before leaving, however, he executed a Jackknife Powerbomb on Jericho and Orton. Nash then stepped away from in-ring action and underwent neck surgery.
