Minnesota Vikings running back Adrian Peterson will not play in Saturday's preseason game, Chris Tomasson of the St. Paul Pioneer Press reports.

Peterson tore his ACL in December 2011. Since then, he has not had a carry during a preseason game.

Peterson returned from his torn ACL in just nine months, and ran for 2,097 yards during the 2012 regular season.

The running back ran for 1,266 yards while playing in just 14 games for the Vikings last season, missing Weeks 15 and 17 with a sprained foot.

Tomasson also reports that cornerback Josh Robinson likely will not play in the game after aggravating a hamstring injury during Wednesday's practice. Captain Munnerlyn will likely start in his place.

The Vikings are likely to go with Matt Cassel as their opening-game quarterback. He's ahead in the battle with veteran Christian Ponder and rookie Teddy Bridgewater, who was taken with the 32nd pick in the first round of the draft.
