WrestleMania XXVII
Starting from the January 31 episode of "Raw", mysterious vignettes began promoting an upcoming event on "2.21.11". On the February 21 edition of "Raw", The Undertaker was revealed as the mysterious figure, who made his return after a four-month absence. However, Undertaker's return was interrupted by a returning Triple H. The two men stared each other down and both peered at the WrestleMania marquee, teasing a possible challenge at WrestleMania XXVII. The match was confirmed four days later on WWE's official website. This match marks the second time the two would face each other at a WrestleMania, the first being WrestleMania X-Seven ten years earlier. Before their WrestleMania match, both men had a face to face encounter on the March 28 episode of "Raw", only to be interrupted by Shawn Michaels, who critictized Triple H for believing that he could defeat The Undertaker at the event, something that Michaels wasn't able to do. After The Undertaker said that Michaels was history, Michaels attempted to superkick him, but The Undertaker retaliated with a chokeslam that was stopped by Triple H, who then asked Michaels why he is going to defeat The Undertaker at WrestleMania. Michaels, however, left the ring, unable to give Triple H an answer, believing that Triple H couldn't defeat The Undertaker at the event.
