Brian Urlacher's tenure with the Chicago Bears has come to an end after 13 seasons.

Urlacher and the Bears were unable to agree to terms on a new deal and both sides agreed to move on.

"We were unable to reach an agreement with Brian and both sides have decided to move forward," Bears general manager Phil Emery said in a statement. "Brian has been an elite player in our league for over a decade. He showed great leadership and helped develop a winning culture over his time with the Bears. We appreciate all he has given our team, on and off the field. Brian will always be welcome as a member of the Bears."
