WWE: Undertaker Retires At 55

He made the announcement known in the last episode of his documentary series 'The Last Ride'.

It is instructive to note that Undertaker has been performing in the ring for 30 years having made his WWF debut in 1990.

He has gone on to win every championship and event possible while also having an incredible winning streak at Wrestlemania that only recently came to an end.

However, he claimed that: "I'm at a point, it's time this cowboy really rides away. There's nothing left for me to conquer or accomplish.

"The game has changed. It's time for new guys to come up. The time just seems right.

"This documentary has helped me discover that and opened my eyes to the bigger picture and not judge myself as harshly these last few years.

"I can do more good outside the ring than I can inside. I'm finally at a place where I can accept that."The Undertaker announces retirement from the WWE as he has 'nothing left to accomplish'
