Chicago Bears perennial Pro Bowler Lance Briggs sat out practice again Thursday, increasing the odds the team will be without the starting linebacker Sunday against the Seattle Seahawks at Soldier Field. Briggs was forced to exit the Bears' 23-6 victory over Carolina after injuring his left ankle. "Lance Briggs' ankle is a little bit of a concern," Bears coach Lovie Smith said Thursday. "Whenever you don't practice for two straight days, it's a little bit of a concern." The Bears are preparing Brian Iwuh to start at weakside linebacker in place of Briggs. http://sports.espn.go.com/chicago/nfl/news/story?id=5685232
