WrestleMania XXVI
WrestleMania XXVI was the twenty-sixth annual WrestleMania professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE), which took place on March 28, 2010, at the University of Phoenix Stadium in the Phoenix suburb of Glendale, Arizona. 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.
WrestleMania XIV
The result of the main event heralded a changing of the guard in the World Wrestling Federation. Shawn Michaels, who had been a major superstar in the company for many years, having won his first WWF World Heavyweight Championship at WrestleMania two years previously, took a four-year hiatus from wrestling due to a severe back injury sustained during the casket match against Undertaker at the Royal Rumble. He made several ostensible one-off appearances as a guest commentator during episodes of "Raw Is War" in the summer of 1998, and eventually replacing Sgt. Slaughter as commissioner at the end of the year, holding onto the position for a year and a half. After what was supposed to be a one-time match four years later at SummerSlam, Michaels and the now renamed World Wrestling Entertainment realized that his injuries had healed, and he made a full-time return to wrestling, retiring in 2010 at WrestleMania XXVI, 12 years after this event.
