Sting revealed in an interview with the Daily Star that World Wrestling Entertainment officials approached and offered him a match with The Undertaker at WrestleMania XXVII, as well as induction into the WWE Hall of Fame.
He declined their offer.
“I wouldn’t say it was utter nonsense, that’s not true!” laughs Sting. “It’s a dream match that fans would want to see. It was close. I’m glad things turned out the way they did.
“There are so many variables. Let’s just say that I turned it down for the same reasons I always have. Something in me never trusted what would happen up there, based entirely on the track record with other WCW guys and everything that went on after Vince bought WCW.
“I wont be watching but I’ll be asking what happened between Undertaker and Triple H.”
Brock Lesnar adds that WWE had not approached him at all regarding an appearance at WrestleMania.
“They were smart enough to know that I am deeply involved in UFC, what I am doing now.
“Wrestling doesn’t affect my life so much. I’m a fighter. The WWE will go on, and it will always be there, but I am in the UFC for as far as I can see. If ever there was an opportunity in the future to be on Wrestlemania, then I guess I have to say: ‘Never say never.'”
