New Orleans Saints running back Chris Ivory has undergone sports hernia surgery, Saints head coach Sean Payton announced after practice Friday.
Ivory, a rookie free agent last season who became a key contributor during the 2010 season, had missed all of camp while still recovering from foot surgery.
Payton said Ivory had the surgery in Philadelphia and that it should be about a three-week recovery period. The Saints' first regular season game is Sept. 8 at Green Bay.
On Thursday the Saints released reserve running back Lynell Hamilton. The top backs healthy right now are Pierre Thomas, Mark Ingram and Darren Sproles.
With newcomers Ingram and Sproles on board and Thomas healthy again, Ivory's playing time was going to be limited even before the surgery. He helped fantasy owners in 2010, but it doesn't look like he'll be helping anyone in 2011 and shouldn't be drafted.
