Running back Willie Parker is changing teams and changing agents.
The Washington Redskins informed Parker on Saturday that he will be released, according to a league source.
Parker, a Pro Bowler in 2006 and 2007, averaged 1,337 yards in three seasons for the Steelers from 2005 to 2007.
He became Pittsburgh's backup last season in his fifth full year as the Steelers turned to Rashard Mendenhall as their featured running back.
Parker finished 2009 with 389 yards on 98 carries.
