Carey (concussion) is questionable for Thursday's preseason game against the Patriots, Larry Mayer of ChicagoBears.com reports.
Carey, who suffered a concussion during the Bears' preseason opener last Thursday, has been limited in practice throughout the week and may not play in the team's second exhibition game. Backup running backs Jacquizz Rodgers and Jordan Howard figure to see additional reps if Carey remains sidelined.
