Posted Dec. 18, 2011
The Saints have placed Ingram on injured reserve, ending his season. Ingram, who won the 2009 Heisman Trophy at Alabama, missed New Orleans' last four games because of a sprained toe on his left foot. Coach Sean Payton says the injury got worse during practice last week and basically ensured he wouldn't be able to catch up in time to contribute this season. Ingram carried 122 times for 474 yards and five touchdowns this season. His longest run was a 35-yard touchdown against the New York Giants on Nov. 28.
