The Chicago Bears are thin at outside linebacker after only signing Aaron Lynch to provide a pass rush opposite Leonard Floyd this season.
Lynch was considered a risky signing in March because of his injury history. He's appeared in only 28 games over the last three years and he's already off to an injured start with the Bears.
Lynch was one of several players to miss Sunday's practice with a hamstring injury, a list that includes fellow starter, Danny Trevathan.
Lynch and Trevathan missed Saturday's practice, too.
Other Bears who sat out on Sunday were Sherrick McManis (hamstring), Daniel Brown (ankle) and Joel Iyiegbuniwe (shoulder).
