On an episode of Pardon my Take, Triple H confirmed Shawn Michaels and Adam Cole will not ever happen. 

“When [Shawn] was leaving, he ran into Adam Cole backstage and they had a moment and Shawn walked off. The internet blew up with people saying, ‘Oh my God, what if? What a tease. It’s the ultimate match.'”

Triple H said Michaels was knee buckling on the ramp, and the fans did not see that. 

“What they don’t know is three minutes prior to that when Shawn’s music hit and he was walking out to the stage, his left knee gave out and he started dancing because he almost fell off the stage. His left knee is so bad that it buckled on him while he was walking down the ramp. That match isn’t going to happen.”
