The event grossed $5.8 million in ticket sales, making the event the highest grossing and attended entertainment event held at the University of Phoenix Stadium.
WrestleMania XXVI
At WrestleMania XXV, Shawn Michaels was unsuccessful in defeating The Undertaker and ending Undertaker's undefeated streak at the event. When the match won the 2009 Slammy Award for Match of the Year, Michaels stated in his acceptance speech that he could still defeat The Undertaker at WrestleMania and challenged him to a rematch. A month later, The Undertaker, then the World Heavyweight Champion, made his reply and refused a rematch. The refusal saw Michaels obsess about facing the Undertaker at the event, attacking referee Charles Robinson and SmackDown general manager Theodore Long respectively after failing his title match opportunities in the Royal Rumble match and Elimination Chamber qualifiers. At the Elimination Chamber event, Michaels snuck into Undertaker's Elimination Chamber match for the World Heavyweight Championship and performed a Sweet Chin Music on The Undertaker, enabling Chris Jericho to defeat The Undertaker and win the World Heavyweight Championship. On the following night, The Undertaker changed his mind and accepted the rematch but with the stipulation that if Michaels loses, he would have to retire. Michaels accepted, noting that if he could not end the streak, there was no reason why his career should continue. Two weeks later, Michaels and The Undertaker agreed on another additional stipulation; that the match would have no disqualifications and no count-outs.
