Vikes' Adrian Peterson should be ready to play Sunday

EDEN PRAIRIE, Minn. -- Adrian Peterson should be ready to play on Sunday against the New York Giants after spraining his left ankle against the Chicago Bears.

A league source said tests on Peterson's ankle showed no further damage, adding that the Vikings running back plans to get treatment all week to be ready for Sunday night's game against the Giants.

Peterson, who was injured in the second quarter on Sunday, returned to the game with 4 minutes, 19 seconds left in the third quarter, carrying six times after he sprained his ankle on a 9-yard run. The running back said X-rays were negative during the game.

The NFL's leading rusher was at the Vikings' facility on Monday, getting treatment on a day that most of his teammates were off after the Vikings' 38-17 win. He appeared to be walking without a limp, and he did not have his ankle in a walking boot.

The Vikings can clinch a playoff spot before they take the field on Sunday night, with a Seattle Seahawks win or an Atlanta Falcons loss. The Vikings would also be assured of a shot at the NFC North title if the Green Bay Packers lose to the Arizona Cardinals on Sunday afternoon.

But even without help, the Vikings can clinch a playoff spot and assure themselves of a NFC North title game at Lambeau Field in Week 17 if they beat the Giants on Sunday night.

It appears they'll have Peterson, who leads the NFL with 1,314 rushing yards, ready to play in the game.
