Jay Cutler injury: Bears' quarterback ruled out Week 11

The Chicago Bears will start Jason Campbell at quarterback on Monday night against the San Francisco 49ers as Jay Cutler will not play due to the concussion he suffered against the Houston Texans. Chicago officially announced Campbell as the starter on Friday.

Cutler left during the second quarter of the Bears' 13-6 loss to the Texans after taking a helment-to-helmet hit by linebacker Tim Dobbins and was replaced by Campbell. The former Redskins and Raiders signal-caller finished the game, going 11-of-19 with 94 yards; Cutler went 7-of-14 for 40 yards before suffering the concussion. Cutler has not practiced this week and Campbell has taken the first-team snaps.

On the season, Cutler has completed 59.2 percent of his passes for 1,814 yards with 12 touchdowns and 10 interceptions. Campbell last started a game for the Oakland Raiders, where he started the first six games of the 2011 season before breaking his collarbone. The Bears signed him in the offseason to serve as a veteran backup to Cutler, who missed seven games last season with a broken thumb.

The Bears also announced that rookie defensive end Shea McClellin would not play against the 49ers. McClellin suffered a concussion in the first quarter against the Texans. He has 2.5 sacks on the season.
