Rountree carried the ball four times for 11 yards in Sunday's 27-24 loss to the Patriots.
The Chargers ran just 18 designed runs on an afternoon in which the Patriots sat on the ball with a successful rushing attack. One game after serving as a healthy inactive, Rountree at least managed to pick up a handful of carries, but he hardly did anything with the opportunities. Primarily a short-yardage ballcarrier, Rountree is averaging a pitiful 2.5 yards-per-carry through 28 attempts this season.
