Ahmed (back) was a full practice participant Wednesday, Cameron Wolfe of NFL Network reports.
Ahmed missed about a week of practice with a back/neck injury suffered in the Dolphins' final preseason game. He could be anywhere between second and fourth on the depth chart for Sunday's opener against the Chargers, as there's no clear order behind starting running back Raheem Mostert with Jeff Wilson (abdomen) on injured reserve. Ahmed can at least be considered a slight favorite for the No. 2 role, considering that's where he's listed on the Dolphins' unofficial depth chart after repping ahead of De'Von Achane and Chris Brooks for most of training camp and the preseason.
