The New Orleans Saints added another piece to the defensive secondary. The Saints signed cornerback Dexter McDougle, a source familiar with the transaction confirmed Tuesday afternoon. ESPN first reported the signing, which later appeared on Tuesday's NFL Transactions report. To make room for McDougle, the Saints placed defensive end Alex Okafor (Achilles) on injured reserve. The 5-foot-10, 195-pound McDougle previously spent time with the Philadelphia Eagles and was waived in early November.
