The Saints added rookie cornerback Arthur Maulet and practice squad defensive back Justin Hardee to the active roster according to the leagues transaction report.
The Saints were thin at the position as cornerbacks Marshon Lattimore (concussion) and Sterling Moore (chest) were ruled out for week 3's matchup with the Carolina Panthers.
New Orleans was set to enter Sunday's game with P.J. Williams, Ken Crawley and De'Vante Harris as the only healthy cornerbacks.
Maulet joined the Saints in May as an undrafted free agent out of Memphis. Hardee was signed to the practice squad following the start of the regular season.
