The Saints signed tackle Bryce Harris on Friday, a source told The Advocate, and released veteran defensive tackle John Hughes to make room. 

Harris, who returned to the Saints this offseason after bouncing around the league, has been the team's emergency tackle option.

He's been on and off the roster this season, and he's been on the 53-man roster twice. With left tackle Terron Armstead and left guard Andrus Peat both battling injury, the Saints might have wanted Harris as insurance in case Armstead or Peat is hobbled on Sunday. 

Hughes, who spent training camp in New Orleans only to be released in the final cut to 53, was on the team for a week before the Saints needed the spot for Harris.
