The Undertaker is still in rough shape physically following his WrestleMania 30 match with Brock Lesnar, where 'The Beast' broke 'The Phenom's' 21-0 winning streak.

'Taker has not been seen on WWE television since his April 6th WM appearance, with deliberate ambiguity being promoted on-screen as to his in-ring future.

It's highly unlikely that The Phenom will be seen on TV for the rest of 2014 even if he is to wrestle again at next year's event, but more doubt has been cast over the reality that The Deadman might not ride again.

Sources close to him claim he is still in 'rough shape' following his last match against Lesnar - on April 6th - as he continues to train in the gym.

In that match he suffered a real-life concussion, which hampered the match quality and added to the catalogue of injuries the banged up 49-year old is carrying.

And people who have pumped iron recently with Undertaker - real name Mark Calaway - have quoted him as saying 'it isn't looking good' for WrestleMania 31.

This wouldn't be the first time there has been serious doubt surrounding The Undertaker's ability to return for a WrestleMania match, and it is entirely possible that the man who prides himself on not giving much away in regards to his character could be attempting to throw the public off the scent.

A renowned proponent of the old-school approach of protecting the business and staying in character at almost all times, it was partly for that reason that real-life hardman/former UFC fighter Lesnar was chosen to end 'The Streak.'

A proud man, Calaway is nonetheless unlikely to want to bow out with a sub-par match against Lesnar rounding off his legacy, and many would feel short-changed by such a send-off for arguably the most respected WWE legend of all-time.

Rumours for one more match with the likes of John Cena or Sting continue to abound, but a decision over Undertaker's ability to perform at WrestleMania 31 likely won't be made until later in the year.

In the last few years there have been question marks hanging over The Undertaker's future before each Wrestlemania event, but a combination of age, physical condition and the loss of 'The Streak' mean the chances of a return are slimmer than ever.

But if we have witnessed his last match, you can rest assured we will see The Undertaker again for a Hall of Fame induction in 2015.
