Carey left Thursday's game and is being evaluated for a concussion.
Carey made a hard hit on special teams in the second half of Thursday's game against the Broncos and came off wobbling, prompting him to enter the concussion protocol. If Carey is forced to miss any time, expect Jeremy Langford, Jacquizz Rodgers and rookie Jordan Howard to pick up the running back slack in the Bear's second preseason game against New England on Aug. 18.
