Vikings put Adrian Peterson and Matt Kalil on injured reserve

The Minnesota Vikings placed Adrian Peterson on injured reserve Friday, another sign that his time with the team could be over following surgery to repair a torn meniscus in his right knee.

NFL teams can pull one player off injured reserve per season, so the Vikings would be able to activate the leading rusher in franchise history sometime down the stretch if he were to heal swiftly. The likelihood of him returning this year, though, is slim given the typical recovery time for the injury he suffered last weekend in the game against Green Bay.

The move created an opening on the active roster, which the Vikings didn’t immediately fill.

Also Friday, left tackle Matt Kalil had surgery to repair a labrum tear in his right hip. He was operated on by team physician Dr. Chris Larson, who performed Peterson’s procedure at Twin Cities Orthopedics the day before. The Vikings called Kalil’s procedure successful, but he’ll miss the first game of his career Sunday when the Vikings (2-0) visit the Carolina Panthers. Kalil, who will be replaced by T.J. Clemmings, also was placed on injured reserve.

Kalil struggled through the first two games at less than full strength. He has started all 66 games, plus two in the playoffs, since the Vikings made him the fourth pick in the 2012 draft out of USC. Kalil’s contract will expire after this season.
