METAIRIE, La. (AP) -- The Saints have placed recently re-instated linebacker Jonathan Vilma on the physically unable to perform list, meaning he'll be out through Week 6, even if he has not been served a new bounty suspension by then.
The Saints have also brought back fifth-year receiver Adrian Arrington, who had been cut on Saturday after struggling with right knee soreness heading into Week 1, and signed offensive tackle Bryce Harris from Atlanta's practice squad.
Vilma is rehabilitating his surgically repaired left knee and did not play Sunday, two days after his suspension stemming from the NFL's bounty investigation was vacated, but not permanently voided, by an appeals panel. The panel directed NFL Commissioner Roger Goodell to reconsider punishment of all four players sanctioned in New Orleans' alleged pay-for-pain bounty pool.
