Trestman made the announcement after the Bears were routed 54-11 by the Philadelphia Eagles on Sunday night
The game against the Packers will be for the NFC North Division title and a playoff spot.
Cutler was sacked five times and completed 20 of 35 passes for 222 yards with one touchdown and one interception before being benched for Josh McCown in the fourth quarter with the game already out of hand.
"We will throw this tape in the trash can," Trestman said. "Coaches will evaluate it and make sure that we clean up the things that we can clean up for next week. I know the guys will come in excited and ready to play Green Bay on Sunday. All we can do at this point is put this one behind us, answer the questions that have to be answered as honestly as we can, and that is that."
