EDEN PRAIRIE, Minn. -- Playing in the season opener has been at the forefront of Adrian Peterson's mind almost since he went down with a torn left ACL in the Minnesota Vikings' second-to-last game of the 2011 season.

How long it has taken other running backs to return from the injury doesn't concern Peterson. The running back has always seen himself as different from everyone else, and he has made it abundantly clear that he expects to play against the Jacksonville Jaguars on Sunday.

He has one more week to make his case to Vikings coach Leslie Frazier and his staff.

Frazier said Monday that the Vikings would not make a decision on Peterson's status until game day, and he cautioned that even if Peterson does return, he shouldn't expect the workload he carried before he was injured just yet.

"We recognize if he's able to get in this first ballgame, it'll be with limited exposure," Frazier said. "We'll talk about it as the week goes on and see how he's doing and if it's even a viable option to let him play."

That means fewer carries than Peterson is used to getting as the workhorse and focal point of the Vikings' offense, and likely more work for backup Toby Gerhart.

Perhaps the biggest obstacle the Vikings have in handling the situation is Peterson's state of mind. He has worked tirelessly to get himself prepared to help his team, throwing himself into the rehab process from the moment he came out of surgery. With the Vikings coming off a 3-13 season, Peterson knows they need him in the backfield to have any chance, and the coaches know it, too.

"You really have to take the emotion out of it," Frazier said. "You have to really hone in on what's best for him, what's best for our team. Adrian is not just another guy on our team. He is in so many ways the face of what we try to do. We have to be able to see the big picture when it comes to him and that's the way we'll approach it."

On a rebuilding team coming off a last-place finish in one of the strongest divisions in the league, the Vikings may not need to rush him back. Peterson said he felt like he was ready to play in the preseason, but the coaches and the team's training staff preferred to take a more gradual approach.

"I'd love to have him out there, that goes without saying for our entire team," center John Sullivan said. "But at the same time, it's out of our hands. I hope he is. But if not, we've got to go forward with the guys that are ready to go."
