Adrian Peterson's sprained left ankle is only at 70 percent.

Fantasy Advice: The Vikings have been out of the playoff picture for weeks now, so they are playing spoiler and also letting Christian Ponder grow. At this point, there is no reason to rush AD back until he is 100 percent. I strongly doubt he plays this week against the Lions. The worse-case scenario would be the Vikings opting to IR Peterson for the rest of the season and leaning on Toby Gerhart. But don't freak AD owners because this is simply my opinion. For now, AD owners have to sit tight and hope he can come back for Week 15's matchup against the Saints.
