The news was first reported by now-teammate DaQuan Jones, whom played alongside Johnson at Penn State as well as with the Titans, and later confirmed by Ian Rapoport. The Bills have no shortage of elite defensive linemen on the roster, with Johnson joining Jones, Von Miller, Ed Oliver, A.J. Epinesa, and Greg Rousseau, amongst others. The team is coming off a season in which they allowed just 18.7 points per game, third in the league, due in large part to their disruptive defensive line. Johnson’s one-year deal is worth a maximum of $4 million.

Johnson suffered an MCL injury and a fractured knee against the Falcons in Week 9. It is another blow for a defense currently without Joey Bosa and J.C. Jackson because of injury. Christian Covington will likely see more snaps with Johnson on the shelf. 

The severity is still to be determined and the Chargers will know more tomorrow, but it sounds like Johnson will probably miss some games. Johnson left the locker room on crutches with a brace on his knee. He left Week 9's game against the Falcons and had to be carted to the locker room.

Johnson was helped off the field by the training staff before being carted from the sidelined to the locker room. Though his return is questionable, it doesn't look like he will return to this game. The Falcons have gashed the Chargers on the ground all game and that will continue with LA's starting nose tackle seemingly done for the day.
