Mankato, MN - Adrian Peterson continues to amaze in his rehabilitation process as Sunday morning AP came off of the Physically Unable to Perform (PUP) list and participated in the Vikings morning walkthroughs.

It was rumored over the weekend that Peterson would be coming off the PUP early this week but to see him out on the field taking handoffs from Christian Ponder and running behind the new look offensive line had to be a sight for the sore eyes of Vikings fans across the Midwest.

"It's good to see Adrian out there in the walkthrough," Head coach Leslie Frazier said Sunday morning.

Peterson underwent surgery to repair a torn ACL in his left knee on December 31st, 2011. Typically the rehabilitation process for an injury of this magnitude is 9-12 months. Only eight months removed from the night he went under the knife, Peterson has taken the last step before returning to the field for the Minnesota Vikings.

"It's just another step in the process," Coach Frazier said. "I want to caution you, I know there are a lot of fans that are very optimistic and excited about seeing him back but for us, it's just a part of the process...The next step for him in the process would be to get integrated with his teammates."

Under the new Collective Bargaining Agreement (CBA), Peterson will have to remain without pads for two days before returning fully to practice with his teammates. Since the Vikings afternoon practices are fully padded, he will only take part in the non-contact installations and drills until Tuesday afternoon's practice.

"He's unique," Frazier said of Peterson. "Daily we'll gauge where he is and if it looks like that's the next step, we want to do it. If we could get him in a game and let him get a little bit of a taste of NFL action in a live situation, that will be good."

If the Vikings plan to use Peterson in week one versus the Jacksonville Jaguars, Adrian will have to undergo a period of full contact football and take some his to both his body and reconstructed knee. According to coach Frazier, that full contact period won't be happening in Mankato.

"I don’t think there'll be a time where we say 'we're live on Adrian,'" Frazier clarified "You don't want him going to the ground in practice. The first time that he'll go to the ground, if I have anything to say about it, will be in a real game situation."

Adrian will be available to the media after Sunday afternoon's practice. Stay tuned to KFAN.com for a full report on Adrian's reaction to being reinstated from the PUP list.
