Here are the grades for the San Francisco 49ers’ 32-17 loss to the Detroit Lions.
GABBERT: C. Posted a passer rating of 106.2 against a defense that was giving up an average opponent passer rating of 101.4 coming into the game. Converted just one-of-nine third downs while throwing short of the first-down marker almost every time. Fumbled the ball, which the Lions recovered at the Niners 1-yard line. Completed the one deep pass he attempted, and offensive coordinator Geep Chryst never called another shot downfield. More on Chryst below.
RUNNING BACKS: B-. Jarryd Hayne had a bad game: 3.
