The 'WWE Universe' will never forget where they were on April 6, 2014. It was the day The Undertaker's famous WrestleMania streak finally came to an end at the hands of Brock Lesnar.
At the Mercedes-Benz Superdome in New Orleans, Louisiana, 'The Beast' stunned WWE fans as he pinned the Phenom to make it 21-1 at the Grandest Stage of them All.
There's no doubt about it, that famous night left 'The Deadman' scarred as he was dominated from start to finish by Lesnar.
And, with Taker approaching his 50th birthday, questions have been asked: will we ever see him in the ring again? Rumours have been rife regarding the potential of one more fight for The Undertaker, but it's something that divides opinion.
Taker looked like a wrestler coming to the end of his career at Mania; he didn't quite look the same as before. He was left with injuries after the showdown with Lesnar, so it may not be wise for him to step foot inside the ring one more time.
One last match?
But, there's a chance that he will. Only he will know if he's got one more battle in him. Taker's return to WrestleMania 31 would be enough on its own to make the WWE Universe stand up and take notice.
Who, then, could he go one-on-one with? We're here to take a look. Scroll through the following pages to see our six potential final 'last matches'
