Apparently, Adrian Peterson hasn't been staying up all night worrying about that 11-game losing streak against NFC North opponents.

"Wow," Peterson said when asked if the streak is stuck in his head. "To be honest with you, that hasn't been stuck in my head because I didn't know it was 11. But, wow, it's a good thing I didn't know. It's time to end that. It's time to get back on track and start playing Vikings football."

Meanwhile, Peterson still isn't ready to declare himself 100 percent healed from the reconstructive surgery he had on his left knee nine months ago. Three weeks ago, he said he was 95 percent.

As for when he'll feel he's 100 percent, Peterson said, "It'll just be me knowing my body. "When I look in the mirror, obviously my right leg is bigger than my left. And I know [my left leg] is not as strong as far as the different things I can do. That's when I'll be able to tell, when I won't be able to tell the difference between the strength in my legs."

Asked if he feels he's knocked the "rust" off after three games, Peterson said, "To be honest with you, I think the rust just got knocked off against San Fran." Peterson carried the ball a season-high 25 times in Sunday's upset of the 49ers.

"The previous two weeks, I woke up on Monday and my body felt great; a little soreness in my knee," Peterson said. "I woke up Monday after this game and I felt like I played some football. I feel [the rust] is knocked off now, And that's what I needed."
