Adrian Peterson leaves with leg injury

One of the few bright spots for the Vikings this season has been the consistent durability and high-end performance from running back Adrian Peterson.

But Peterson moments ago was helped off the field with a leg injury after being tackled awkwardly against the Raiders.

Peterson lost his shoe before impact, and the leg twisted as he was dragged down by Raiders safety Michael Huff.

Peterson, who had 26 yards on six carries plus a touchdown, currently is being evaluated on the sidelines.  They are working on his ankle.
