LAKE FOREST, Ill. (AP) -- The Chicago Bears say quarterback Jay Cutler will miss Monday's game at San Francisco because of a concussion.
Jason Campbell is expected to start against the 49ers in his place.
Cutler's status was in question after he sat out the second half of Sunday's loss to Houston. The Bears believe he was injured on a helmet-to-helmet hit by the Texans' Tim Dobbins, who was fined $30,000 by the league, late in the second quarter.
Cutler initially did not show any symptoms and took seven more snaps in the first half. It wasn't until halftime that the symptoms showed up, and the Bears went with Campbell in the loss to Houston.
