PITTSBURGH -- Pittsburgh Steelers defensive coordinator Keith Butler has informed the team he is retiring, the Steelers announced Saturday evening.
"It is an emotional day as I announce I am retiring from my football coaching career," Butler said in a statement. "I have spent every year since 1990 as a coach in the NFL and the NCAA, but the time is right for me to walk away after a successful career both playing and coaching the game I love."
Butler, 65, has been with the Steelers organization for 19 years and took over for Dick LeBeau as defensive coordinator in 2015 after 12 seasons as the linebackers coach.
