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). First-round pick Roquan Smith remains a holdout.
Lynch is in a training camp battle with Sam Acho for a starting job and will have to hold off Kylie Fitts and Isaiah Irving as well. The more time he loses to injury, the less and less likely the chances are that he'll become an impact player on defense.
It's still early, and the Bears have an extra week of training camp because of the Hall of Fame game. There's plenty of time for Lynch to get healthy and put this hamstring issue behind him.
