Clinton-Dix, 27, played for the Bears on a one-year deal in 2019, when he posted 78 tackles and two interceptions, with both of those picks coming in a win on Sept. 23 at Washington.
Clinton-Dix signed his short-term deal with the Bears last year hoping to prove himself entering a new contract year in his prime.
"I know who I am as an individual," Clinton-Dix said in December. "There's things I've done the past five years that put me in this situation. I had a chance to correct it. I've been doing it throughout the year. I'm just excited about this opportunity.
"Turn the tape on."
A first-round pick by the Packers in 2014, Clinton-Dix spent parts of five seasons in Green Bay. He was traded to Washington in October 2018 for the season's final nine games, then signed with Chicago last March.
The departure of Clinton-Dix was expected for the Bears, who now officially have a void alongside Pro Bowl safety Eddie Jackson.
