[ESPN.com] The Washington Redskins made their biggest free-agent splash Friday night, signing running back Larry Johnson to a three-year contract.

The deal is worth $3.5 million and could reach as much as $12 million total with incentives.

Johnson, a two-time Pro Bowl pick who has run for 6,219 yards and 55 touchdowns in eight NFL seasons with the Kansas City Chiefs and Cincinnati Bengals, is expected to work with incumbent Redskins running back Clinton Portis.
