Veteran offensive guard Josh Sitton will get another chance to test the free-agent market next month. The Chicago Bears are declining to pick up Sitton's $8 million contract option for next season, sources informed of the situation told NFL Network Insider Ian Rapoport and NFL Network's Tom Pelissero. He's set to become a free agent when the new league year starts March 14. Chicago also won't bring back linebacker Jerrell Freeman for 2018. With the decision, Sitton enters the free-agent market for the second time of his career after the Green Bay Packers released him just before the start of the 2016 season.
