According to NFL Network reporter Mike Garafolo, Peterson agreed to a one-year deal with the Skins and he'll get a chance to go up against his former teammates in Week 1 as the Redskins travel to Arizona on September 9 for a matchup against the Cardinals. Two backups, Samaje Perine and Byron Marshall, are out with ankle injuries.
The Washington Redskins have turned their attention to a pair of available running backs with serious legacies to their name as they hope to shore up a thin corps at running back. On the other side of the equation, Washington appears to be Peterson's only option, at least without a significant injury to a running back elsewhere before Week 1. "We've had very unlucky situations with our running backs".
Peterson is the Vikings'all-time leader in career rushing yards (11,747), career rushing attempts (2,418), and career rushing touchdowns (97). He has played in only 13 games and ran for only 601 yards the last two seasons combined.
The Redskins open the regular season September 9 at Arizona.
