Vikings rule Peterson out for Sunday’s finale

The Minnesota Vikings have ruled out running back Adrian

Peterson for their final game of the season.

The Vikings announced Saturday they downgraded Peterson from

doubtful on the original injury report to out against Detroit

Sunday, when the Vikings and Lions will play the last game at the

Metrodome.

Peterson sprained his right foot Dec. 8 at Baltimore and sat out

the following week against Philadelphia. He played last Sunday at

Cincinnati but was mostly ineffective. Peterson acknowledged

afterward the injury affected his performance. He has also been

bothered this year by a sore groin.

Peterson finished the season with 1,266 yards rushing, the

second-lowest total of his seven years in the NFL.
