Vikings' Adrian Peterson: Not ready to start running

Although Peterson has started rehab for his knee injury, he is not ready to start running. "It's still going to be a while before it's safe for him to run," Vikings athletic trainer Eric Sugarman told the Minneapolis Star Tribune. "Sometimes it's our job to protect them from themselves so he doesn't do too much too soon."

Analysis:

Peterson had surgery in late September to repair a torn meniscus, which usually requires 3-to-4 months of recovery. It sounds like he's making progress and there's some hope he can return this season, but it's too early to guess at a specific timetable.
