Bears quarterback Jay Cutler has left Chicago's game against the Houston Texans because of a concussion.
A scrambling Cutler took a helmet-to-helmet hit from Tim Dobbins after unleashing a pass on third down at midfield late in the first half Sunday night.
There were offsetting penalties on the play. Cutler got called for an illegal forward pass because he was beyond the line of scrimmage and then got drilled by Dobbins, who was called for unnecessary roughness.
Cutler stayed in for the rest of the half, but Jason Campbell came out to start the third quarter.
The Bears also lost defensive end Shea McClellin because of a concussion in the game's opening minutes.
