New England Patriots running back Dion Lewis missed the end of the team's 27-10 win over the Washington Redskins with a knee injury.
The 25-year-old, who had 14 rushing yards and 39 receiving yards during the game, suffered the non-contact injury during the third quarter at the Gilette Stadium.
He was able to walk off the field unaided, but was quickly ruled out by the team after being assessed in the locker room.
Lewis has scored four touchdowns so far this season for the Patriots.
