"Making their biggest splash in a relatively quiet free agency period, the Redskins on Friday signed veteran running back Larry Johnson, whose off-the-field problems have at times overshadowed his on-field exploits.

The team would not release terms of the deal, but a person with knowledge of the negotiations said Johnson signed a three-year contract that carries a base salary of $3.5 million and could be worth $12 million with incentives.

The Redskins hope Johnson, 30, will complement running back Clinton Portis in their revamped offense and also push Portis on the practice field.

Johnson, a two-time Pro Bowler, was released by the Kansas City Chiefs last year after making offensive remarks and played the final seven games of the season with the Cincinnati Bengals as a reserve. On the year, Johnson had 581 yards on 178 carries and no touchdowns in 14 games. His last 1,000-yard season was 2006, when he rushed for a career-high 1,789 yards and scored 17 touchdowns. "
