Peterson, who was placed on injured reserve on Sept. 23, tore his meniscus Sept. 18 against the Green Bay Packers. The 31-year-old All-Pro "is back to running again, although light running," according to Mike Florio of Pro Football Talk.
He is still getting treatment on his knee following his September surgery. His expected timetable to return is in December.
The Vikings have the worst rushing attack in the NFL.
Last week, Vikings coach Mike Zimmer said that he has "no idea" if Peterson will return this season.

In September PFT reported that Peterson's "sole focus" is playing again this season.
Peterson was averaging just 1.6 yards per carry before being injured. He has 57 yards from scrimmage on 33 touches this season. The Vikings are averaging just 69.8 rushing yards per game and a measly 2.7 yards per carry.
For fantasy football purposes, Peterson is worth watching. If you are in a keeper league and he was dropped, I would add him, especially if you have a spot for injured reserve. For season-long leagues, wait for more information to emerge regarding his return. The Vikings have important matchups down the stretch against the Dallas Cowboys, Green Bay Packers, and Chicago Bears.
