Vikings' Adrian Peterson: Set to miss time due to meniscus injury

NFL Network's Ian Rapoport suggests that with Peterson slated to undergo right knee surgery Thursday, the running back is "likely out until December at least."

Analysis:

Added details regarding Peterson's status/timetable should arrive once coach Mike Zimmer addresses the media, but it's clear that the running back is going to miss a decent chunk of time. In his absence, Jerick McKinnon and Matt Asiata are on track to head the Vikings' backfield.
