Raiders sign WR Javon Walker, OT Kwame Harris

The Oakland Raiders signed former Pro Bowl receiver Javon Carter and free agent offensive tackle Kwame Harris, adding two offensive players the team hopes will help quarterback JaMarcas Russel. Walker will receive a $6 million signing bonus and $5 million in salary in each of the first two years. The six-year deal could be worth up to $55 million, a person familiar with the contract said on condition of anonymity because the terms were not released. Harris is guaranteed $3 million in the first year of his deal that would pay him $16 million over three years, the person said. The signings fill positions of need for the Raiders, who are trying to build their offense around Russell, the first overall pick in last year’s draft. Oakland also has renegotiated running back Dominic Rhodes contract this week, securing his return for next season. Rhodes was due a $2 million roster bonus on Friday, but agreed to restructure his deal. Rhodes signed as a free agent last year after helping Indianapolis win the Super Bowl. He was suspended for the first four games last season and played sparingly until Justin Fargas went down with a knee injury late in the year. Rhodes ran for 237 yards the last two games of the season and is expected to share the load with Fargas next season.
