Saints' running back Reggie Bush will not play in Monday night's game in Atlanta, the team confirmed Saturday.
Bush had been listed as questionable after an MRI this week indicated he has a partially torn left knee ligament.
A person familiar with Bush's injury told The Associated Press Bush likely would not risk further aggravating the injury by playing again this season.
That person requested anonymity because of the delicacy of the situation. Coach Sean Payton has called such talk premature.
The team did not make any comments about Bush's prospects for the remainder of the season.
Bush became the Saints' featured running back when a knee injured ended Deuce McAllister's season in Week 3.
So far this season, Bush has scored six touchdowns with 581 yards rushing and 417 yards receiving. He has 10 dropped passes and fumbled eight times, with the Saints recovering all but three of those.
With Bush out, the active running backs will be Jamaal Branch, Aaron Stecker and rookie Pierre Thomas.
