Stone Cold's role was taken by The Undertaker.
It initially looked like Stone Cold was going to be a key part of WrestleMania XL, yet ultimately, his spot was taken by The Undertaker in Roman Reigns vs. Cody Rhodes II.
Speaking on Grilling JR, Austin’s real-life friend, Jim Ross discussed Austin’s absence, and he believes Austin wasn’t involved due to a monetary issue:
“I haven’t talked to Steve in several weeks, but I’m assuming that, if I was guessing, and that’s all it would be right now, as I sit here in Jacksonville Beach, Florida, I would say that cash had a major role in why Austin was not at WrestleMania this year. Because there was a spot there at the end where all those guys were getting their flowers, their props, their attaboys, and getting their stuff over et cetera, et cetera that would have fit Steve perfectly.”
