The Saints cornerback is expected to be placed on injured reserve with a broken ankle suffered in New Orleans' win over Atlanta, sources told NFL Network Insider Ian Rapoport and NFL Network's Mike Garafolo.
Rapoport added that Robinson will require surgery to repair torn ligaments in the injured ankle.
Robinson recorded career highs with Philly last season, but wasn't making much of an impact in New Orleans' 30th-ranked pass defense. Robinson played in 56 percent of New Orleans' defensive snaps through three games and also participated on special teams. He tallied seven tackles.
