During his rehabilitation, Henry bragged about his assault on Undertaker, until vignettes began playing promoting The Undertaker's return. The Undertaker returned at Unforgiven on September 16, defeating Henry. Batista and The Undertaker reignited their feud at Cyber Sunday with the fans choosing the special guest referee Stone Cold Steve Austin, but Batista retained the World Heavyweight Championship. They battled again inside Hell in a Cell at Survivor Series, where Edge returned and interfered to help Batista retain the World Heavyweight Championship. In response to this, The Undertaker delivered a "Tombstone Piledriver" to General Manager Vickie Guerrero on the November 23 episode of "SmackDown!", sending her to the hospital. Returning assistant-General Manager Theodore Long declared a triple threat match for the title between the three men at Armageddon, which Edge won after interference from The Major Brothers.
