CHARLOTTE, NC (FOX 46/AP) - Panthers quarterback Cam Newton was shaken up and helped off the field late in the third quarter after being sacked for the sixth time, but he didn't miss a play.
The team said it was an ankle injury.
Newton remained on the ground for several minutes after Bills defensive end Jerry Hughes beat left tackle Matt Kalil with a spin move and corralled the quarterback in the backfield on third down, forcing a Carolina punt. It appeared that Hughes' knee hit Newton in the head.
Newton was taken under a blue tent on the Carolina sideline but emerged with a football and began throwing passes.
He played the next Carolina offensive series.
Panthers tight end Greg Olsen will miss the remainder of the game against the Buffalo Bills with a right foot injury.
Olsen sustained the injury in the first half and team announced that he will not return Sunday.
The sturdy, reliable Olsen has not missed a game in the last nine seasons. He is the only tight end in NFL history to record three straight 1,000-yard seasons.
