Bills CB A. Williams injures right knee
Williams made a tackle after a 34-yard reception by Johnson early in the third quarter. He remained on the grass for a few minutes while trainers looked at him.
He was helped to his feet and helped off the field before being carted to the locker room. The team says his return is questionable.
