Saints RB Chris Ivory inactive

BALTIMORE -- The New Orleans Saints will be without leading rusher Chris Ivory for Sunday's game with the Baltimore Ravens.

Ivory has been declared inactive after experiencing hamstring problems in last week's victory against St. Louis.

An undrafted free agent out of Tiffin University, Ivory took on a prominent role for the Saints after Reggie Bush and Pierre Thomas suffered major injuries early in the season.

Ivory has carried 130 times for 683 yards and five touchdowns.

The Saints have been easing Bush back into the rotation since he first returned in a Thanksgiving game with Dallas. Thomas made his return last week after suffering an ankle injury in late September.

Bush and Thomas likely will get the bulk of the work at running back today, but Julius Jones also could be used as a backup.
