The Vikings continue to monitor RB Adrian Peterson's recovery from ACL surgery.
"My goal is to be able to go out and participate somewhat during training camp," he said. "How much, I'm sure, the staff will evaluate things and let me know. I'm just going to go with the flow. The main thing for me right now is getting back the strength in this left leg, getting the quad, the hamstring and the calf (healthy). Just building those muscles and trying to get it as equally strong as my right leg."
Peterson expects to be ready when Minnesota opens the season Sept. 9 against the Jacksonville Jaguars.
The team is cautiously optimistic that its star ball carrier will be able to start on Week 1. But head trainer Eric Sugarman said in May that Peterson's playing time would be determined by a consensus of opinion among Peterson, his surgeon, the Vikings' medical staff and the team's front office.
