Dolphins' Storm Duck: Carted off

Duck (knee) has been ruled out for the remainder of Sunday's game against the Falcons.

Duck was carted off the field after sustaining a knee injury in the fourth quarter. The starting cornerback had already missed the Dolphins' last six games due to an ankle injury, making his second start of the year Sunday. Miami will look to backups Kendall Sheffield and Ethan Bonner to help at cornerback.
