EDINA, Minn. -- As expected, Adrian Peterson tried running last week for the first time since undergoing knee reconstruction, and the results were what the Minnesota Vikings wanted.

"Did a great job," coach Leslie Frazier said before an Athletes in Action lunch event at the Westin hotel. "Everybody was impressed. Our trainer, Eric Sugarman, was really impressed with his movement and the things he was able to do. He's on schedule. He's doing well."

Peterson, 27, tore the anterior cruciate ligament and medial collateral ligament in his left knee on Dec. 24 at Washington. He underwent surgery six days later with Dr. James Andrews, who selected the therapists Peterson has been working with much of the offseason at his home in Houston.

Eric Sugarman, the Vikings' head athletic trainer, has been in daily contact with Peterson and visited him in Houston as well. Running last week matched the timeline Sugarman laid out for reporters in January, saying it would take about three months for the patella tendon from which Peterson's new ACL was grafted to be strong enough.

Asked if anyone put a parachute on Peterson to keep him from running too hard, Frazier laughed and said, "We had that conversation, too.

"He said, 'How fast should I go?' We're trying to just judge movement, and he wants to run a 4.3 40. But he has to let that graft continue to heal. He understands that there's a time frame he's working within, and so far, so good."

Peterson returned to Houston after spending last week in Minnesota and is expected back at Winter Park in two weeks, Frazier said.
