Adrian Peterson could return by mid-to-late December as he continues to make solid progress in his recovery from a right lateral meniscus tear.

Peterson underwent surgery on Sept. 22nd.

Peterson had an exam late last week and could start running this week.

Peterson could return on Dec. 18th or Dec. 24th.

The Vikings waived Ronnie Hillman on Monday, adding defensive end Stephen Weatherly to their active roster. The move left them with just Jerick McKinnon and Matt Asiata at running back, but an eventual Peterson return would change the dynamics of the Vikings' offense.
