Bears quarterback Jimmy Clausen suffered a concussion during Saturday's preseason loss to the Bengals. Head coach John Fox says Clausen experienced delayed symptoms after the game.
Third-stringer David Fales will likely see most of the snaps Thursday against the Browns.
The Bears are (2-1) in the preseason. Thursday's game can be heard on Newstalk 1060 with the Pre-Game Show at 6:30.
