McKissic suffered a neck injury in Monday's 17-15 win over the Seahawks, Nicki Jhabvala of The Washington Post reports.
McKissic hit his head on a defender in the fourth quarter and remained down on the field for several minutes after the collision. He ultimately was carted off the field, though the team doesn't yet know the severity of the injury. Optimistically, teammates said that McKissic was walking around the locker room after the game. More clarification on his status should come as the week progresses.
