The Detroit Lions have signed former New York Jets cornerback Justin Miller in an attempt to fill a position weakened by their dismissal of the legally challenged Aaron Berry and the loss to injury of Chris Greenwood. The Lions have also cut wide reciever Marcus Harris. Miller was drafted by the Jets in 2005's second round and last played for the team in 2009. The Lions terminated Berry's contract Monday after his second arreste of the summer. Greenwood is recovering from abdominal surgery.
