10 Most Heartbreaking Major WWE Defeats

4. Shawn Michaels Vs. The Undertaker (WrestleMania XXVI)

There will never be another Shawn Michaels.

By coming back from (what was considered in 1998) a career-ending back injury to arguably have an even better run the second time around, HBK cemented his place in history as one of the best. There's a reason Shawn became known as 'Mr. WrestleMania. On WWE's grandest stage, he couldn't help but shine the brightest.

2010 would mark his last show-stealing performance. 12 months prior, his match with The Undertaker at 'Mania 25 had been an instant classic, so the pressure was on to top that with another vintage effort.

It didn't quite match the quality of the previous effort, but the career-ending stipulation ramped up the emotion. Deep down, people knew this was the last Shawn Michaels match they'd see. Saying goodbye was almost unbearable.
