Lewis caught a screen pass and was making a cut when he appeared to reach for his knee late in the third quarter. He was on the field for a while being attended to by the team's medical personnel.
He walked off the field slowly on his own and straight to the steps behind the bench that lead to the locker room. On his way, defensive coordinator Matt Patricia stopped him, put his arm around Lewis and said something to him.
A few minutes later the team announced he would not return to Sunday's game.
