Crawford (concussion) has been ruled out for Sunday's game against the Seahawks, Brad Biggs of the Chicago Tribune reports.
Crawford will miss his second straight game while he remains in the NFL's five-step concussion protocol after first suffering the head injury in the Bears' Week 14 loss to Green Bay. The 26-year-old cornerback has been a minor contributor for the Chicago secondary this season, logging 15 tackles over 13 games.
