Falcons running back Jason Snelling, who has filled in admirably as a backup at fullback and halfback, did not practice on Thursday.
Snelling suffered a hamstring injury in the Dallas game, but head coach Mike Smith did not have to issue an official injury report, per league rules, until Thursday.
It was the latest blow for the Falcons, who are hoping to get running backs Ovie Mughelli (calf) and Jerious Norwood (right hip flexor) back for the Saints game on Monday night in New Orleans.
Snelling's injury also led to the Falcons signing running back Aaron Stecker on Tuesday.
