Derby (foot) was a full participant in Wednesday's practice, Armando Salguero of the Miami Herald reports.
Derby hasn't seen the field since Week 3, despite having logged multiple full practices since that time. The veteran tight end continues to nurse a lingering foot injury, and evidently, his full practices haven't been enough to lessen the Dolphins' concern about his health. Even if Derby is cleared to play Sunday against the Packers, it seems likely that he'll be forced to settle for a limited role behind fellow tight ends Nick O'Leary and Mike Gesicki.
