De'Von Achane 'week-to-week'

Dolphins RB De'Von Achane avoided a severe injury to his shoulder, HC Mike McDaniel told reporters Monday. But according to NFL Network's Cameron Wolfe, the rookie RB is considered "week-to-week." That's a particularly tough spot for a young back who has been running fifth on the RB depth chart so far. We'll see whether Achane can return to the field before the regular-season opener. We're moving him down the RB rankings for upcoming fantasy football drafts, though.
