The New Orleans Saints placed running back Chris Ivory on the reserve physically unable to perform list amid several roster moves that cut the team's active roster down to the required 53 players.

Ivory, New Orleans' leader in rushing yards as a rookie in 2010, is recovering from a pair of offseason surgeries. The 23-year-old went under the knife in January to repair a Lisfranc sprain to his left foot, then had a sports hernia procedure performed just prior to camp.

The undrafted free agent, who totaled 716 yards on 137 carries and scored five touchdowns last year, won't be eligible to return until the Saints host Indianapolis on October 23.

New Orleans also released tight end Tory Humphrey, offensive tackles Jordan Black and George Foster, safeties Pierson Prioleau and Chris Reis, cornerbacks Trumaine McBride and Quincy Butler and linebacker Clint Ingram. In addition, running back Chris Taylor, who was placed on injured reserve Wednesday, was released with a settlement.

Blake is an eight-year veteran with 40 career starts, nine of which came with Jacksonville last season. The 34-year-old Prioleau is in his 13th year in the league and third with the Saints, and had also played under current defensive coordinator in previous stops in Buffalo, Washington and Jacksonville.

Safety Paul Oliver, signed as a free-agent in the offseason, was placed on injured reserve with an undisclosed condition, as were running back Patrick Cobbs (undisclosed) and rookie wide receiver/return specialist Joseph Morgan (knee). Rookie defensive end Greg Romeus, a seventh-round selection in this past year's draft who's recovering from back surgery, will begin the season on the reserve non-football injury list.

Also waived during Saturday's cuts were tight ends Tyler Lorenzen and Michael Higgins, wide receivers Montez Billings and Andy Tanner, linebackers Dwight Roberson and Nate Bussey, defensive tackles Dexter Larimore and Swanson Miller, quarterback Sean Canfield, cornerback Terrail Lambert, long snapper Kyle Nelson and center Cecil Newton. Wide receiver Jarred Faison was released with an injury settlement.

Newton is the older brother of Carolina Panthers quarterback and 2011 No. 1 overall draft pick Cam Newton.
