Adrian Peterson doubtful against Falcons

It’s looking like the Atlanta Falcons won’t have to worry about Minnesota running back Adrian Peterson on Sunday.

The Vikings have released their Friday injury report and they listed Peterson as doubtful. He hasn’t practiced all week due to a sprained ankle. Without Peterson, the Vikings might have to ask more of rookie quarterback Christian Ponder and the passing game.

The Falcons have been particularly good at defending the run recently. They held Tennessee’s Chris Johnson to just 12 yards last week. Atlanta also has a 13-game streak of not allowing an individual running back to rush for 100 yards.
