The Saints re-signed veteran offensive lineman Khalif Barnes, as first reported by ESPN's Adam Caplan. Barnes was present at Wednesday's practice. The Saints have not yet announced a corresponding move, but four players were absent from practice during the portion open to the media: LT Terron Armstead, G Senio Kelemete, CB Delvin Breaux and DE Obum Gwacham. Armstead (knee), Breaux (fibula) and Kelemete (hamstring) have been dealing with injury issues that leave their status in doubt for Sunday's game at San Diego. … Barnes, 34, spent the final week of the preseason with the Saints after playing the last 11 years with the Raiders and Jaguars. He has the versatility to play tackle and guard.
