The Undertaker says he's unable to remember participating in his legendary match against Brock Lesnar at WrestleMania 30 because he suffered a concussion in the first few minutes.

Undertaker talked about the night his WrestleMania streak ended on the first episode of WWE Network's Broken Skull Sessions with Steve Austin.

"Somewhere within the first five minutes of this match, I get concussed," he confirmed to Austin. "I don't even remember this night." Adding, "My last memory I can definitively tell you happened at about 3:30 in the afternoon when my wife came backstage and we had a conversation. That's the last thing that I remember on my own of that day."

Taker says his memory picks up around 5 am the next day in the hospital being asked his name and location, which he was unable to answer. The only thing he remembered was his wife's name.

The 54-year-old wrestling legend says he can't figure out where the concussion occurred, but notes that it wasn't Brock Lesnar's fault. "This screwed me up," he continued. "This screwed up my confidence. You figure after you've had a career 25 plus years, you've seen every situation, you don't get shook up. Well that is a false belief cause this shook me up. Because I couldn't pinpoint where I got concussed."

Undertaker says he also refused to end his career on a match he couldn't remember, which is why he didn't end retire after the streak ended.

The first episode of Broken Skull Sessions is available now on WWE Network.
