Mark Calaway, known by his in-ring name "The Undertaker," has retired after three decades with the World Wrestling Entertainment (WWE).
Calaway made the announcement in the fifth and final episode of "The Last Ride," a documentary series that aired on the WWE Network.
"Never say never," said the 55-year-old wrestler. "But at this point in my life and my career, I have no desire to get back in the ring."
"I'm at a point, this time… the cowboy really rides away," he added.
Calaway's last appearance was at WrestleMania 36, when he defeated AJ Styles in the "Boneyard Match," a cinematic affair that was heavily praised for its action sequences and style.
The victory gave The Undertaker a 25-2 win-loss record at WrestleMania. He famously had a record streak of 21 consecutive wins at the Showcase of the Immortals -- a streak broken by Brock Lesnar at WrestleMania 30 in New Orleans. He also lost to Roman Reigns at WrestleMania 33.
A seven-time world champion in the WWE, Calaway did say that he was not entirely closing the door on a possible return.
"If (WWE owner Vince) McMahon was in a pinch, would I come back?" he mused. "I guess time will only tell, there. In case of emergency, break glass, you pull out The Undertaker. I would have to consider that."
WWE fans paid tribute to The Undertaker on social media, calling him an icon and a legend.
