BUT even if he is, it does not mean that the Vikings will activate him. They can leave him inactive as healthy scratch (with pay) the last three weeks.
Sports Illustrated's Peter King reports Adrian Peterson is "likely (but not certain) to be reinstated next week."
Peterson's appeal was heard this week, and it's now in the hands of league appeals officer, Harold Henderson. Henderson has rarely, if ever, sided with the player, so it'd come as a surprise to see Peterson win, especially after it was reported earlier in the week that the NFLPA wasn't confident about Peterson winning the appeal. If Peterson wins, it will then be the Vikings' call whether to activate him for Week 15. It's a true toss-up at this point. Stay tuned.
