CHARGERS PASSING GAME: Quarterback Philip Rivers is an MVP candidate in his 15th season, with 31 touchdown passes against eight interceptions and a career-best average of 8.8 yards per attempt. He might be without his top target, Keenan Allen, who left the Chargers’ last game with a hip pointer and missed practice on Tuesday. But Rivers has plenty of other options, including big-play threats Mike Williams and Tyrell Williams, both of whom average 16 yards per catch. Melvin Gordon, a dangerous receiver out of the backfield, seems on track to return after missing the last three games with a sprained right MCL. Ageless tight end Antonio Gates remains a sure-handed target. The Chargers rank eighth in passing yards per game and second in yards per attempt.
