Lake Forest, IL (SportsNetwork.com) - Chicago Bears coach Marc Trestman told reporters Friday that linebacker D.J. Williams has a pectoral muscle injury that could be season-ending.
Williams left Thursday's win over the New York Giants with the injury. Jon Bostic replaced him in the lineup.
The 31-year-old Williams has 27 tackles, two sacks and one forced fumble in six games (four starts) this season.
