Minnesota Vikings running back Adrian Peterson has been listed as 'questionable' for their game with the Green Bay Packers on Sunday.
Peterson has been hampered by a groin problem in recent weeks and although he expected to start, he may well be limited for the important NFC North clash.
The problem has meant that Peterson has missed significant practice time this week.
Last season's star man has 104 carries for 851-yards so far this season, with nine rushing touchdowns to his name.
