Vikings’ Peterson out at least one game after suffering knee injury at Lambeau

The good news for the Vikings is that he won’t be gone as long as initially feared.

>EDEN PRAIRIE (AP) – As Adrian Peterson was prone on the Lambeau Field turf, his football future flashed before his eyes as a searing pain radiated from his right knee.

“That pain was horrible. I don’t know if you’ve ever experienced pain where you don’t want anybody to touch you. Just be still for a few minutes until it calms down. That’s the kind of pain it was,” Peterson said. “Not really knowing what to expect because it was my knee. I was just praying, ‘God please, don’t let it be anything serious.’ “

He spent a sleepless Sunday night at his home in Eden Prairie, with the worry getting so great that he found himself doing a self-examination of both knees to see if he could detect any differences, all in the hope of finding some comfort.

After getting an MRI exam on Monday, Peterson should be sleeping much better now.

The rookie sensation, who just a week earlier set the NFL single-game rushing record with 296 yards against San Diego, will miss at least one game with a torn lateral collateral ligament. But the injury is not deemed serious enough to require surgery or jeopardize Peterson’s season.

“I was very relieved. It could’ve been a lot worse,” Peterson said. “I just thank God. I’ll be back soon.”

Vikings coach Brad Childress ruled Peterson out for Sunday’s game against Oakland, but wouldn’t put a timetable on his recovery beyond that.

Team doctors told Childress that with ligament tears graded on a three-point scale, with three being the worst, Peterson’s tear is “two-plus.” It’s not as serious as an anterior cruciate ligament tear.

“He’s lucky,” head athletics trainer Eric Sugarman said. “If he’s 30 degrees in front with that foot fixed, we’re talking about a very significant injury today. So he’s very lucky that this is all he has.”

Peterson was injured in the third quarter Sunday. Packers cornerback Al Harris hit him in the knee just as Peterson was about to make a cut downfield, and he writhed in pain for several minutes in a scary scene.

“I remember just making my cut, trying to beat one guy, and he came out of nowhere,” Peterson said.

Losing the only offensive star it has will be a devastating blow to a unit that has struggled in every game Peterson has not topped 200 yards rushing this season. It’s been a one-man show in Minnesota, with Peterson accounting for 1,081 of the team’s 1,551 yards rushing and eight of the team’s 10 touchdowns rushing.

In addition to making history two weeks ago against the Chargers, the No. 7 overall draft pick out of Oklahoma was on pace to smash Eric Dickerson’s record for yards rushing by a rookie in a single season.
