CLEVELAND -- The Chicago Bears are taking a conservative approach to the preseason finale.

With the regular season opener 10 days away, the Bears appear to be resting all of their starters and several key reserves in the fourth preseason games against the Cleveland Browns.

The Bears made no official announcement except that rookie David Fales will start at quarterback in place of Jay Cutler, but nearly every member of the first-team offense and defense participated in pregame warm-ups without pads or helmets.

That list of players included: linebackers Jon Bostic and Shea McClellin, and right tackle Jordan Mills, who missed the first three preseason games with a foot injury.

Even certain backups seem to be getting the night off.

Wide receiver Josh Morgan, running back Ka'Deem Carey, wide receiver Micheal Spurlock, defensive end Trevor Scott and defensive tackle Ego Ferguson wore baseball caps instead of helmets while teammates went through pregame drills.

Safety Chris Conte (concussion) made the trip to Cleveland, but is not expected to play.

However, veteran guard Eben Britton is scheduled to make his preseason debut.

The Bears must reduce their roster from 75 to 53 by Saturday afternoon.
