Chargers RB Ryan Mathews (calf, questionable) missed practice Friday after taking limited reps Thursday and is questionable for Week 17. The downgrade is worrisome for Mathews. If he can't go Mike Tolbert would be a terrific play against a shaky Raiders rush defense. Tolbert (hamstring, probable) took full practice reps Friday after missing practice earlier in the week and is probable for Week 17.
