The release of Adams will be the first personnel transaction completed under the new front-office regime headed up by new general manager Phil Emery.
A ninth-year veteran, Adams played the first seven games of the 2011 season -- starting two -- but was inactive for five of the team's next eight outings. Adams hadn't been inactive in that many contests since the 2008 season.
Nagging injuries, including a strained calf during training camp, contributed to Adams' struggles. Bears coach Lovie Smith also cited mediocre practice performances as one of the reasons for the veteran's drastically reduced playing time. The emergence of Matt Toeaina and Henry Melton also likely contributed to Adams' release.
Adams registered 17 tackles and eight quarterback pressures in 2011, finishing the season without a sack for the first time since 2008.
Adams was set to enter the final year of a two-year deal signed just before the start of training camp, and was scheduled to receive $1.9 million in base salary while counting $2.65 million against the team's salary cap.
