Green Bay Packers star Aaron Rodgers left Sunday's game against the Detroit Lions and is being evaluated for a concussion.
Rodgers left in the first quarter and did not return after halftime. He was replaced by DeShone Kizer.
Rodgers sent Packers fans into a state of panic in the opening week of the regular season when he headed to the locker room in the first half against the Chicago Bears with a knee injury. However, he returned to lead Green Bay to a 24-23 victory. But the knee injury lingered all season, which affected his performance.
