ASHBURN, Va. — The Washington Redskins have added yet another veteran running back to the roster, agreeing to terms with Willie Parker for a one-year deal.

Parker agreed Friday to a contract that could be worth as much as $3.1 million with incentives.

The Redskins already have 28-year-old Clinton Portis returning, and they recently signed 30-year-old Larry Johnson to a three-year, incentive-laden deal.

Parker is 29 and has played six seasons with the Pittsburgh Steelers, winning two Super Bowl rings. He has three 1,200-yard seasons, but ran for only 389 yards last year as a backup.

Parker's agent, Douglas Hendrickson, said the Redskins have told Parker that "it's an open competition for the starting job."
