Peterson dinged up

Vikings star running back Adrian Peterson revealed that he has been battling an ankle injury for the past three weeks and that he aggravated it Sunday against the New York Giants.

The All-Pro limped off the field in the first quarter after taking a hit and fumbling the ball. He then ran for a 67 yard touchdown on the team's next drive.

"It feels pretty good," Peterson said. "I’ve been fighting with this ankle injury the past three weeks. Going out on Sundays I take a lot of shots in the legs, so it got twisted up on that play and it was pretty painful."

Meanwhile, Vikings coach Brad Childress said there’s only a "small chance" that defensive end Ray Edwards will play Sunday. Edwards injured his left knee last week while making a tackle. Brian Robison will start in his place.

Childress said Pro Bowl nose Williams, who has missed the past two games because of a broken right shoulder, is expected to do some work in practice. Williams has said the plan is for him to play.

For the Eagles, running back Brian Westbrook was limited in practice today with knee and ankle issues. Tight end L.J. Smith (shoulder) also was limited. Defensive end Victor Abiamiri (foot); guard Shane Andrews (back); linebacker Stewart Bradley (rib, groin); and tackle Jon Runyan (knee) did not participate. Andrews will obviously miss the game as will Abiamiri. Bradley and Runyan are expected to go.

Wide receivers Hank Baskett (knee) and Kevin Curtis (calf); safety Brian Dawkins (back) and guard Todd Herremans (shoulder, ankle) were able to participate in all drills.

Meanwhile, the NFL granted the Vikings a 24-hour extension on the television blackout deadline. Minnesota now has until 4:30 p.m. (et) Friday to reach a sellout and allow the game to be shown on local Fox affiliate. The Vikings announced this morning they had 11,000 tickets remaining for Sunday.
