It's a little more than a week away, and Minnesota coach Leslie Frazier still isn't sure if the goal will be met.
Following the Vikings' 28-24 preseason finale loss at Houston on Thursday, Frazier called Peterson a "game-time decision" for next Sunday's home game against the Jacksonville Jaguars.
"We've got a lot of things we want to get done with him this week," Peterson told reporters. "I doubt that we would know without getting him through an entire week if we thought he were ready to play in a football game. We need to take him through some things this week."
Peterson, who had surgery to repair two torn knee ligaments and returned to practice less than eight months later, was activated from the physically unable to perform list on Aug. 12 and returned to practice in team drills two days later. He started taking contact during practice this week after being ruled out for the entire preseason a week ago.
Frazier also said offensive lineman DeMarcus Love aggravated his shoulder/pectoral injury and would be re-evaluated. Rookie receiver Jarius Wright, who had six catches for 122 yards, including a 59-yard touchdown reception, suffered a sprained ankle and didn't return. Wright wrote, "Thank everyone for the prayers. I'm fine. #muchlove" on his Twitter page after the game.
Frazier said linebacker Marvin Mitchell, perhaps the top backup at the position, also sprained an ankle on the first series of the game and didn't return. The coach said neither Wright nor Mitchell has the more severe high-ankle sprain.
