Update: Montgomery returned to the game in the third quarter.
Both starting running backs have exited the Bears-Giants game.
Shortly after seeing his counterpart Saquon Barkley leave with an apparent right leg injury, Bears running back David Montgomery headed to the locker room as well.
Montgomery leaped through the line of scrimmage on first-and-10 and was hit by Giants defensive lineman Austin Johnson. He appeared to land on his head as B.J. Hill drove him into the ground.
The Bears announced it as a neck injury and said he is questionable to return.
Montgomery walked off the field without help and was evaluated in the injury tent before being taken to the locker room.
If he’s out, the Bears are down to Tarik Cohen, Cordarrelle Patterson and Ryan Nall at running back.
Montgomery had five carries for 23 yards and a 28-yard touchdown catch before the injury. The Bears were ahead 10-0.
Last season, as a rookie, he led the Bears with 889 yards rushing and seven offensive touchdowns. He had 74 yards of total offense in the season-opening win at the Lions.
