Chicago Bears pass rusher Khalil Mack is questionable for Sunday’s game against the Indianapolis Colts with a knee injury.
Mack was limited for the third consecutive practice. Cornerback Sherrick McManis, the team’s primary slot cover man, is doubtful.
Mack had one-half quarterback sack, two hits and a forced fumble at Atlanta in Week 3.
Outside linebacker Robert Quinn is not listed on the injury report. Quinn and Mack are the ideal bookend pass rushers for defensive coordinator Chuck Pagano, who prepares to face his former team Sunday.
Bears running back David Montgomery appeared on the injury report Friday with a wrist injury, but was again a full participant in practice. He will play Sunday.
