After more than 30 years as a Fox studio analyst, former NFL coach Jimmy Johnson is retiring from the network, he announced Monday on “The Herd with Colin Cowherd.”

“As you know, probably the most fun I’ve ever had in my career, and that’s counting Super Bowls and national championships, was at Fox Sports,” Johnson said. “I have an absolute ball with my friends on the set, and the best friends I’ve ever had there with Fox. And I’ll tell you on top of that, I love working for Eric Shanks, our CEO, and our producer Bill Richards, but I’ve made an extremely difficult decision.

“I’ve been thinking about it for the last four or five years, and I’ve decided to retire from Fox, and I’m going to miss it. I’m going to miss all the guys, and I’ll see them occasionally, but it has been a great run starting back 31 years ago.”

Johnson had been a part of the original Fox NFL studio crew in 1994. He was there for two seasons, then later returned to “Fox NFL Sunday” in 2002.

Johnson began his coaching career as an assistant at Louisiana Tech in 1965, ultimately becoming head coach of Oklahoma State in 1979, the University of Miami in in 1984, and the Dallas Cowboys in 1989.

He won the 1989 national championship at Miami, then two Super Bowls with the Cowboys in the early 1990s.
