EDEN PRAIRIE, Minn. (AP) - 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 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 Minnesota Vikings' star running back has always seen himself as different from everyone else, and he has made it abundantly clear that he expects to play against Jacksonville on Sunday.

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

Frazier said on 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 should expect a lighter workload.
