The main match on the Raw brand was Triple H versus Batista for the World Heavyweight Championship, which Batista won by pinfall after executing a Batista Bomb. The predominant match on the SmackDown! brand was John "Bradshaw" Layfield versus John Cena for the WWE Championship, which Cena won by pinfall after performing an FU. Another primary match on the SmackDown! brand was The Undertaker versus Randy Orton, which Undertaker won by pinfall after performing a Tombstone Piledriver.
