EDEN PRAIRIE, Minn. – Minnesota Vikings running back Adrian Peterson has been ruled out of today’s game because of a sprained left ankle.

The Vikings announced Saturday that Peterson had been downgraded on the injury report from doubtful to out and would not travel with the team to Atlanta to play the Falcons. This will be only the fourth game in Peterson’s five-year NFL career that he will miss.

Toby Gerhart will be the featured runner.

The Vikings also waived wide receiver Stephen Burton and signed tight end Allen Reisner from the practice squad.

PANTHERS: Jeremy Shockey is listed as probable for today’s game in Indianapolis, but linebackers Omar Gaither and Jason Phillips did not make the trip. Gaither will miss the game because of a knee injury and Phillips is out with a calf injury.
