Cutler has been sidelined for the Bears since tearing a groin muscle during the week seven loss to the Washington Redskins, allowing McCown to fill in at quarterback and help his side to a 27-20 win over the Green Bay Packers on Monday.
Cutler admitted that it was tough for him to watch the action unfold from the sidelines, but backed McCown's ability to keep the side going in his absence.
"I want to be out there. I wanted to be out there Monday night. It's just hard seeing how much time and effort the rest of the guys in the offense and the rest of the guys on the team put in and not being able to help and do my part. That's the hardest part," Cutler told ESPN.
"But that's why we have Josh. That's why Josh takes his job so seriously, for situations like that. I've just got to trust in the fact that he's gonna go out there, he's gonna do everything he can do to help us win games."
The Bears are currently one of three teams tied at the top of the NFC North with a 5-3 record.
