Bears quarterback Jay Cutler out for Sunday's game vs. Ravens
Trestman said that Cutler is "week to week, and it certainly won't be this week."
Cutler came back from a groin injury early and played most of the Bears' 21-19 loss to the Detroit Lions.
Backup Josh McCown came on in relief of Cutler with 2:17 left to play in the fourth quarter and led them to a touchdown in the fourth quarter.
KING: MMQB: NFC's tight playoff races mean a wild final seven weeks await McCown has completed 42 of 70 passes for 538 yards and four touchdowns this season and has a passer rating of 103.
