Packers quarterback Aaron Rodgers exited early against the Bears after getting sacked in Sunday's game, and was later carted to the locker room.
Rodgers was sacked by Roy Robertson-Harris on a third-down situation in the second quarter. He appeared to fall on his left knee.
Rodgers walked off the field with some assistance, and looked to have trouble putting weight on his leg.
After getting it checked out in the medical tent, Rodgers was taken to the locker room. DeShone Kizer came in for the Packers at quarterback.
The 34-year-old Rodgers was carted into the locker room last October during a Week 6 game against the Vikings after injuring his shoulder and underwent surgery.
