METAIRIE - New Orleans Saints coach Sean Payton says cornerback P.J. Williams is expected to make a full recovery by this offseason from a traumatic blow to the head that occurred during Sunday's game against the New York Giants.

Payton, who discussed Williams' health on Thursday, says the decision to place Williams on injured reserve this week was "an easy one" because doctors made it clear that Williams would require significant rest to recover from a concussion the coach describes as one of the "more severe" he has seen.

Williams was knocked unconscious when he absorbed a knee to the helmet during a collision with Giants tight end Larry Donnell.

Payton says Williams is again doing normal daily activities and that he saw the second-year pro having breakfast at Saints headquarters on Wednesday.
