GREEN BAY, Wis. -- Aaron Rodgers' season started with a knee injury and ended with a concussion.
The Green Bay Packers quarterback left Sunday's season finale against the Detroit Lions after just three series. He took a hard hit on his first drop-back of the game, got sacked by linebacker Jarrad Davis and lost his helmet on the play. He stayed in for two more series before he walked to the locker room with a member of the medical staff.
It's at least the third known concussion of Rodgers' NFL career.
