Injuries: Adrian Peterson long shot to play Sunday

Carolina Panthers running back Christian McCaffrey (shoulder) is expected to play Sunday after sitting out practice on Wednesday, according to NFL Network Insider Ian Rapoport.

The rookie out of Stanford has 736 yards from scrimmage and has scored five touchdowns in 11 games this season.

Tight end Greg Olsen is battling soreness in his foot and is not expected to play, a source said. There is no structural or long-term issue but the team is being cautious with the game being on turf. It should be a short absence, according to Rapoport.

The Panthers (8-3) travel to Atlanta to face the Falcons (8-3) in a battle for NFC South supremacy.
