It marked the third time in seven games Chandler left the game due to injury.
"You're always concerned for any player who gets hurt in the game, particularly with concussions," coach Dick Jauron said.
The Bears coaching staff has tried to shelter Burris from being put in a position he doesn't feel comfortable, which is on the football field at this point. However, with Jim Miller on Injured Reserve and Chandler status in doubt it's time for Burris whether he's ready or not.
Burris completed 8-22 passes for 50 yards and had two critical fumbles, but his struggles can't be completely put on his shoulders.
The offensive line struggled with line calls, which allowed the Panthers defense to stunt and use other line tricks to get to the quarterback.
Carolina sacked both Burris and Chandler twice.
The running game went nowhere, especially in the first half when the Bears totaled 10 yards rushing on 11 carries. Chicago finished with 55 yards rushing.
