As of right now, the only healthy running backs on the Miami Dolphins roster is Raheem Mostert and Chris Brooks. Jeff Wilson Jr. was placed on injured reserve as he is dealing with a couple of injuries while De’Von Achane is nursing a shoulder injury he sustained a couple of weeks ago. Salvon Ahmed is now dealing with a neck injury he got from last week’s preseason game. Now we are still a week away from the regular season. Achane and Ahmed could be ready to go by then. If not, it’s going to be up to the veteran Mostert and the undrafted rookie Brooks.
