Minnesota Vikings running back Adrian Peterson is questionable for Sunday's game against the Philadelphia Eagles.

Peterson has a sprained right foot and isn't a lock to play, but his progress encouraged the Vikings on Friday.

"He was able to plant, he was able to push off," Vikings coach Leslie Frazier said. "We'll see tomorrow if there's any soreness, but he looked far better than I anticipated."

Peterson has acknowledged the foot is bothering him.

"There's pain there, but it comes to a point where you've got to suck some of the pain up," Peterson said. "As far as me trying to put pressure on it, the pain that I do feel, I'm able to take that. But it's a different force when you're running and you're really planting and really being explosive."

Although the Vikings are 3-9-1 and out of playoff contention, Peterson said he's not looking to shut it down.

"That's just not my mentality -- leaving these guys out to dry," Peterson said. "I love the game too much to sit out, just because. If I'm out, you're going to know that, 'Hey, he can't go.' That's going to be the case. But outside of that, I'm going to try to put my best foot forward to get out there and play every Sunday."
