Arizona receiver Larry Fitzgerald and running back Rashard Mendenhall are active against the Saints after their availability was in doubt this week.
The Saints have scratched running back Mark Ingram, who struggled early this season and missed practice this past week with a toe injury.
Also inactive for New Orleans on Sunday were nose tackle Brodrick Bunkley and defensive end Tom Johnson, who'd been listed as questionable, along with second-year receiver Nick Toon, a healthy scratch.
Saints rookie defensive end Glenn Foster (ankle) is active for the first time, while defensive end Tyrunn Walker (knee) also returns.
Arizona had ruled out only linebacker Kevin Minter previously. The Cardinals have scratched running back Ryan Williams, offensive linemen Bobby Massie and Earl Watford, tight end D.C. Jefferson and defensive tackle Dan Williams.
