Minnesota Vikings running backs Adrian Peterson and Toby Gerhart are not expected to play in Sunday's game against the Philadelphia Eagles due to injury, NFL Media Insider Ian Rapoport reported Sunday per a source. According to Rapoport, Peterson may still push to play and possibly could even work out on the field before the game. However, team sources said late Saturday that he almost certainly will be out. This was a mild surprise, because as of early Saturday, players were informed that the belief was Peterson might be able to play, per Rapoport. Instead, it's unlikely now. KTWN-FM first reported the improbability of Peterson and Gerhart being in the Vikings' lineup Sunday.
