The team signed Anderson in late July to fill a roster void created when Sedrick Ellis retired.
The eighth overall pick of the 2007 NFL draft by Atlanta, Anderson was selected by the Falcons when Bears general manager Phil Emery served with the club as its director of college scouting. Anderson started 48 of 77 career games played with the Falcons (2007-10), Colts (2011) and Bengals (2012), with whom he played just two contests before missing the rest of the season because of a quadriceps injury.
Anderson has 132 career tackles, 7½ sacks (with just 4½ coming over four years with the Falcons), 10 pass breakups, two forced fumbles and one fumble recovery.
