On the following episode of "SmackDown!", The Undertaker lost to JBL in a number-one contender's match, once again due to interference from Orton. With this, The Undertaker resumed his feud with Orton. At SummerSlam, Orton defeated The Undertaker in a WrestleMania rematch. The storyline intensified as the two taunted each other with caskets, leading to a handicap casket match at No Mercy, in which The Undertaker lost to Randy and his father "Cowboy" Bob Orton. After the match, the Ortons poured gasoline on the casket and set it on fire. When the charred casket was opened, however, The Undertaker had once again vanished. He returned at the Survivor Series, emerging from a burning casket. The Undertaker returned on "SmackDown!" in early December to haunt Orton and set up a Hell in a Cell match at Armageddon. After winning the match, Calaway took a brief hiatus from professional wrestling.
