The Chargers have many problems, but a familiar one just raised its head.
Running back Ryan Mathews has left the game with a left shoulder injury, and is doubtful to return. Mathews has struggled with durability and ball security, but today’s injury was to the opposite side as his broken collarbone earlier this season.
UPDATE 5:26 P.M. ET: The Chargers announced that Mathews won’t return.
