A person with knowledge of the surgery says New Orleans Saints running back Mark Ingram underwent an arthroscopic procedure on his knee.
The surgery was performed Thursday, the person says on condition of anonymity because the team has not announced it.
The prognosis is for Ingram to return well before training camps open at the end of July.
Ingram, the 2009 Heisman Trophy winner at Alabama, was slowed by a turf toe injury in his rookie NFL season. He had left knee surgery while in college.
Ingram gained 474 yards on 122 carries and scored five touchdowns rushing for the Saints last season.
