State Farm Stadium
The stadium hosted the WWE event WrestleMania XXVI which took place on March 28, 2010, with 72,219 fans in attendance. This was the first WrestleMania since WrestleMania XI with a non-title match as a main event, the first WrestleMania to be held in the state of Arizona and the third to be held in an open-air venue, after WrestleMania IX and WrestleMania XXIV. 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 XXVIII
WrestleMania consisted of professional wrestling matches that involved different wrestlers from pre-existing feuds or storylines that played out on WWE's primary television programs. Wrestlers portrayed villains or heroes as they followed a series of events that built tension and culminated in a wrestling match or series of matches.
The main event of WrestleMania XXVIII pitted The Rock wrestling against John Cena. On the February 14, 2011 episode of "Raw", The Rock was revealed as the host of WrestleMania XXVII, and upon his return to WWE, began a feud with John Cena (and Cena's opponent at that WrestleMania, then-WWE Champion, The Miz), which continued for weeks in terms of verbal insults, until the March 28 episode of "Raw", where Cena delivered the Attitude Adjustment to the Rock after he fended off attacks from the Miz and Alex Riley. At WrestleMania XXVII, the Rock got involved in the main event WWE Championship match between The Miz and John Cena, which initially ended in a double count-out. After the match was restarted under no disqualifications, no count-outs rules, the Rock delivered a Rock Bottom to Cena, thus enabling the Miz to win the match. The next night on "Raw", Cena challenged the Rock to a one-on-one match; Rock accepted and proposed that it be held at WrestleMania XXVIII. After winning the championship from The Miz at Extreme Rules, Cena interrupted The Rock's birthday celebrations during the May 2 episode of "Raw" to announce his intention to defend the WWE Championship against The Rock at WrestleMania XXVIII. Such intentions were however thwarted by Cena losing the title against CM Punk at Money in the Bank in July. At Survivor Series in November, Cena teamed with the Rock (who wrestled his first WWE match in almost eight years, last competing at WrestleMania XX), and billed as "the most charismatic tag team", and defeated the Miz and R-Truth. After the match, The Rock gave a Rock Bottom to Cena.
A second main event, billed as the "end of an era", saw the Undertaker face Triple H in a Hell in a Cell match. The previous year at WrestleMania XXVII, in a No Holds Barred match, The Undertaker defeated Triple H via submission, in their second encounter at a WrestleMania (the first being at WrestleMania X-Seven in 2001, where the Undertaker won as well). However, in the post-match events, due to the harsh physicality suffered during the bout, the Undertaker, for the first time in his career, was carted away from the Georgia Dome by the medical staff on a stretcher. After a near ten-month long hiatus, The Undertaker returned on the January 30, 2012 episode of "Raw", confronting and challenging Triple H to a rematch at WrestleMania XXVIII. The Undertaker, having been dissatisfied of his post-WrestleMania match scenario the previous year, stated that he "did not want 'that scene' to be a lasting memory" of him and was willing to give Triple H "another chance at immortality". After Triple H refused to accept the challenge the next week on "Raw", his close friend and WWE Hall of Famer, Shawn Michaels appeared on the February 13 episode of "Raw" to instigate him in accepting The Undertaker's challenge, which was in vain as Triple H stated he was willing to put his ego and personal agendas aside for the future of WWE, and viewed The Undertaker's 19–0 undefeated WrestleMania streak as a "brand" to cash-in for the company, finally ending the argument saying he would not be the one to end it. Then, on the February 20 episode of "Raw", The Undertaker still remained adamant in getting a WrestleMania rematch with Triple H, going so far as to label Triple H as a "coward", and comparing his abilities and career to that of Shawn Michaels. Enraged by these comments, Triple H finally accepted The Undertaker's challenge at WrestleMania XXVIII, saying that if "he [Undertaker] wanted an end, they would go all the way", and proposed that they would compete in a Hell in a Cell match. On the March 5 episode of "Raw", Michaels confronted Triple H again; Michaels expressed his views on who was better than the other, predicted Triple H's chances of defeating The Undertaker and revealed himself as the special guest referee in their Hell in a Cell match at WrestleMania.
