CHICAGO (CBS) — The Bears don’t know yet how long quarterback Jay Cutler will be out after suffering a groin injury in Sunday’s loss to the Redskins, but head coach Marc Trestman said the quarterback is headed for an MRI on Monday morning.

“We’ll know more later this morning,” Trestman said. “He’s going to get an MRI this morning and probably later this afternoon we’ll probably have the results.”

Cutler left the game in the second quarter, in obvious pain, after he was sacked by Redskins nose tackle Chris Baker.

Cutler rolled over Baker as he was being tackled and stayed down. Players from both teams were seen immediately signaling for the trainers. Although Cutler walked off the field gingerly on his own power, he was seen getting on a cart in the tunnel to take him to the locker room.

Trestman praised backup quarterback Josh McCown, who led the Bears on four scoring drives in the second half.

“He just did a good job managing the huddle, the offense, getting the ball spread around, mixing up some runs, and the guys stepped up around him, and made some plays,” Trestman said.

The Bears are reportedly set to sign back up quarterback Jordan Palmer.

Two other key Bears — linebacker Lance Briggs and cornerback Charles Tillman — finished the game on the sidelines after suffering injuries, and Trestman said the bye week and 14-day break should hopefully help the team rest up and heal in time for the next game against the Packers two weeks from Monday.
