EDEN PRAIRIE, Minn. (AP) — Adrian Peterson has tried to play through a sprained foot and a lingering groin injury, but he is doubtful to play in Sunday’s final regular-season game at home against the Detroit Lions.

Peterson is third in the league in rushing with 1,266 yards. He practiced on a limited basis this week for the Minnesota Vikings (4-10-1), who on Sunday play the final game in the Metrodome’s history.
