Wilson (undisclosed) isn't practicing Wednesday, Barry Jackson of the Miami Herald reports.
Neither is Salvon Ahmed (head), while De'Von Achane (shoulder) is sporting a non-contact jersey. Oft-injured Raheem Mostert and undrafted rookie Chris Brooks are the only healthy running backs on the Dolphins' initial 53-man roster, though at least one or two of Wilson, Achane or Ahmed should be ready for the team's Sept. 10 season opener versus the Chargers. Wilson has been absent from practice since an early exit Aug. 9, with head coach Mike McDaniel thus far declining to provide details on the injury.
