Ivory, who led the Saints with 716 rushing yards and five touchdowns in 2010 despite playing in just 12 games, has yet to recover from offseason foot surgery or sports hernia surgery. After missing all of training camp on the failed physical list, he'll be out at least six weeks before he's allowed to return to practice.
By placing Ivory on the PUP list, the Saints will head into Thursday night's season opener at Green Bay with four running backs, including first-round pick Mark Ingram and free-agent acquisition Darren Sproles. Joique Bell earned his way onto the roster after leading the team during the preseason with 182 yards on 31 carries.
Ivory, at least for now, isn't thinking about his place on the depth chart when he returns.
"They say everybody has their role on this team," Ivory said. "I just feel like I have a role, and I'm not sure what role it is that they want to use me as, but when that time comes, there we go."
Meanwhile, safeties Chris Reis and Pierson Prioleau were let go after being key members of the Saints' special-teams unit the past two seasons.
Prioleau served as the special-teams captain in 2010 and led the Saints with 21 tackles on that unit.
New Orleans kept just two tight ends on the roster -- Dave Thomas and Jimmy Graham -- and two fullbacks, Kory Hall and Jed Collins.
With depth issues at defensive end -- the Saints released Alex Brown in the first round of cuts and starter Will Smith is suspended for the first two games for violating the NFL's banned-substance policy -- New Orleans kept Junior Galette, Jeff Charleston, Turk McBride and first-round draft pick Cameron Jordan.
New Orleans released tight ends Tory Humphrey, Michael Higgins and Tyler Lorenzen; offensive tackles George Foster and Jordan Black; cornerbacks Trumaine McBride, Quincy Butler and Terrail Lambert; linebackers Clint Ingram and Dwight Roberson; wide receivers Montez Billings, Andy Tanner and Jarred Fayson; defensive tackles Dexter Larimore and Swanson Miller; running back Chris Taylor; quarterback Sean Canfield; center Cecil Newton and long-snapper Kyle Nelson.
