Allen (hamstring) took part in practice Wednesday, Adam H. Beasley of the Miami Herald reports.
Allen departed last Sunday's loss to the Jets early due to injury, but his presence on the field for the first practice of the new week suggests he's on track to suit up for the Dolphins' next contest against the Saints in London. He'll assume his usual starting role at safety and attempt to keep Drew Brees and the Saints' prolific passing game in check.
