Adrian Peterson (ankle) returned to practice on Thursday, making it more likely that he will play on Sunday vs. the Lions. Christian Ponder (hip) was limited and his status is still up in the air. Both will likely be game-time decisions, but if they can't go Toby Gerhart will start at running back and Joe Webb will start at quarterback.
