The New Orleans Saints have ruled out strong safety Kenny Vaccaro for the game against the Buffalo Bills. 

Vaccaro, who suffered the injury in the first half of last week's win over Tampa Bay, told reporters on Friday that he doesn't expect the injury to linger. 

Left tackle Terron Armstead, who did not practice on Wednesday or Thursday, returned to practice on Friday, and the Saints have ruled him as questionable for Sunday's game.

New Orleans also might get back the services of right guard Larry Warford, who missed the last two weeks with an abdominal strain but practiced all week. Warford is also questionable.

Wide receiver Michael Thomas and defensive end Alex Okafor, who were both listed with ankle injuries during the week, received no designation, meaning they will likely play.
