Cena won the match and retained the championship after pinning Orton. The primary match on the SmackDown! brand was a Last Man Standing match for the World Heavyweight Championship between The Undertaker and Batista, which ended in a no-contest after both men failed get to their feet before the referee counted to ten. The featured match on the ECW brand was Bobby Lashley versus Team McMahon (Umaga, Vince and Shane McMahon) in a Handicap match for the ECW World Championship. Vince won the title and the match for his team after pinning Lashley.
