The St. Paul Pioneer Press' Jeremy Fowler reports Adrian Peterson has been diagnosed with a high-ankle spain.
Peterson is one of the league's most durable players and a noted quick healer, but he's still likely to be sidelined for a minimum of 2-4 weeks. That means the running load in Minnesota will fall on Toby Gerhart, and fantasy players can expect to be without this season's fourth most productive running back through at least mid-December. Gerhart struggled against the Raiders on Sunday and has a tough Week 12 matchup in the Falcons, but is still a must add in all formats. Lorenzo Booker is third on the depth chart for the Vikings.
perhaps your information is a slightly stale, but rotoworld reported the following:
Vikings coach Leslie Frazier confirmed Monday that Adrian Peterson has a Grade 1 high left ankle sprain.
The Grade 1 characterization is the most mild high ankle sprain possible
. Peterson is still going to be very questionable to play in Week 12, but glass-half full fantasy owners can view it as a positive with a matchup with Atlanta's stout run defense on the slate. While Peterson is one of the league's most durable players and a noted quick healer, he's still likely to be sidelined for one game
. That means the running load in Minnesota would fall on Toby Gerhart and Percy Harvin. Gerhart struggled against the Raiders on Sunday and has a tough Week 12 matchup, but is still a must add in all formats. Harvin may actually get the biggest boost in terms of surefire fantasy starters. The Vikings have used him at tailback in I-formation packages this season. He carried the rock five times in Week 11.
While this is still quite unsettling for an adrian peterson owner, myself, it's still a more optimistic outlook than from your source.
