WWE's 7-time world champion and most decorated Wrestlemania wrestler finally retires at age 55

The Undertaker has finally called it time on his career and admitted he has 'no desire' to return to the ring after 30 years of wrestling professionally.

The seven-time champion made the announcement on the final episode of the 'Last Ride' a documentary series specially created for him.

Mark Calaway made his final appearance at Wrestlemania 36 when he defeated AJ Styles in a Boneyard Match.

"I believe I'm at a place now, post-Boneyard, which was a hellacious battle against one of the best in the business.

"Here you are, climbing on your motorcycle and taking off.

"There was a lot of thought and a lot of emotion, one of those being 'are you happy enough with that?'

"It was a powerful moment. You don't necessarily always get those. If there was ever a perfect ending to a career, that right there was it."

However, the 55-year-old claimed he could return into the ring if chairman Vince McMahon would grant him permission.

"If Vince was in a pinch, would I come back? I guess time would only tell there.

"[But] at this point in my career, I have no desire to get back in the ring."

Undertaker made his first-ever appearance back at Survivor Series 1990 when teamed up with Ted DiBiase's Million Dollar Team.

He had a 21-0 streak of Wrestlemania victories until he was stopped by Brock Lesnar in 2014.
