Seattle Seahawks running back C.J. Prosise (ankle) did not participate in practice on Thursday.
Prosise hasn't practiced since injuring his ankle in Week 3, leaving his status looking murky for Sunday. If the second-year back is unable to play, J.D. McKissic will assume the passing down role with Thomas Rawls and Eddie Lacy splitting the early-down work for Seattle.
Prosise has rushed just 8 times for 20 yards this season but has added 6 catches for 87 yards in 3 games.
