Waller (concussion) was a full participant at Friday's practice, Darren Urban of the Cardinals' official website reports.
Waller is set to return from a one-game absence for Monday's contest in Arizona, but he doesn't figure to see many snaps, likely working behind all of Steve Smith, Kamar Aiken and Marlon Brown. The Ravens might eventually give Waller a longer look, as the team clearly isn't headed for the playoffs and already knows what it has in Brown and Aiken.
