A fifth-year veteran, Anderson has started in 17 of 62 games for the Bears, contributing 120 tackles, 21.5 sacks, in addition to five forced fumbles, 13 tackles for lost yardage and seven pass breakups.
As a rookie, Anderson racked up 12 sacks, most ever by a Chicago rookie since 1993, when Richard Dent tallied 13.5 sacks.
Anderson received a second-round tender offer from the team, which means if he would have signed an offer sheet with another team during the free-agency period, the new club would have been required to give the Bears a second-round draft pick in 2011 as compensation.
