In addition to working out wide receiver Laurent Robinson, the Dolphins are looking at more receivers, Barry Jackson of the Miami Herald reports. Former Colts receiver Austin Collie also is on Miami’s radar. Collie sustained a season-ending knee injury in the third game last season and has had three concussions in his career. Other free agent receivers still available include Randy Moss (highly unlikely for Miami), Chad Johnson (even more unlikely), Brandon Lloyd, Early Doucet, Donald Jones, Donald Driver, Brandon Stokley, Deion Branch and Ruvel Martin. Former Dolphins receiver Greg Camarillo also is looking for work. “We’re always looking to improve, whether from within or without,†coach Joe Philbin said when asked about the receivers.
