Vikings RB Peterson progressing with running at facility (Yahoo Sports)

Minnesota Vikings running back Adrian Peterson is moving forward in the recovery from surgery on his right knee. Peterson ran some short sprints in the team's indoor facility on Tuesday, while the athletic training staff supervised and his teammates went through practice. With five games remaining in the regular season, there's no timetable for Peterson's return, but the four-time All-Pro pick could still be ready for action sometime in December.
