While WWE Universe has seen many Superstars and legends come and go, but not many have the kind of impact that the ‘Deadman’ Undertaker (whose real name is Mark William Calaway) has had. He is one of the greatest Wrestlers on the wrestling fraternity.

Recently, there has been a lot of speculation about the WWE future of Undertaker. The Deadman was last seen in memorable Hell in a Cell match with Shane McMahon at Wrestlemania 32.

While he gave his fans several breath-taking moments to cherish for a lifetime, few photographs which have emerged on social media recently seem not good news for his fans.

At 51, he is now definitely an elderly in the pro wrestling game.

The 51-year-old Undertaker appears to be living up to the moniker as he looks every bit his age. He can be seen using crutches to walk.

The images showing him leaning on crutches have surface leaving his fans shocked.

Undertaker is the most successful Superstar of all-time in pro wrestling’s Super Bowl event, boasting a 23-1 record.

Brock Lesnar has defeated the sure-fire Hall-of-Famer at “WrestleMania 30,” ending the so-called “Streak” after 20 straight ‘Mania wins.

He hasn’t officially announced his retirement yet. He was pulled from two live WWE events in the United Kingdom earlier this year.
