"It goes back to 1989. I was playing with the (Chicago) Bears and Brad Muster was a huge fan of 'the Nature Boy' and wrestling," Harbaugh said, adding Muster asked him if he wanted to go to a show that was near Chicago, and it was backstage where he met Flair.

"(Flair's) infectious personality, just instant friends," Harbaugh said. "The cool part was they said you 'Grab a towel, you and Brad are on the hype squad,' and (I) just remember going out and and cheering for Ric. Been to many of his shows and competitions, and he's one of a kind, the best."

Harbaugh said his energy level was already high heading into the week, but the visit from "the Nature Boy" elevated things for him and his team.
