MANKATO, Minn. -- The Minnesota Vikings began reporting to training camp on Thursday morning.

By day's end, they were expected to finalize a move that's been a virtual inevitability for months.

Two NFL sources said the Vikings planned to place Adrian Peterson on the active/physically unable to perform list before their first walkthrough on Friday, barring the unlikely event the star halfback can talk them out of it.

Peterson, 27, is recovering from surgery for the torn anterior cruciate and medial collateral ligaments in his left knee suffered on Dec. 24 against Washington.

The Vikings and Peterson roundly have said their goal is to have him on the field for the Sept. 9 opener at Jacksonville. But he's less than seven months removed from reconstruction surgery, and placing him on active/PUP gives the Vikings flexibility in case he has a setback.

On May 31, coach Leslie Frazier said no decision had been made but added that "in my mind right now, it'd be better to be doing things on the side (in camp) until we know and feel comfortable that he can get out there and interact with the players."

Players on active/PUP can be activated at any time. Once a player is activated, he's ineligible for reserve/PUP, which sidelines him for at least six weeks.

The Vikings expect Peterson to be ready well before that, but it could be weeks before he participates in a practice. One possible target date is Aug. 12, the first day back to work after the Aug. 10 preseason opener at San Francisco.

The first walkthrough of camp is at 10:30 a.m. Friday.
