The Raiders released running back Dominic Rhodes on Monday, a move precipitated by their trade Sunday of cornerback Fabian Washington.The Raiders absorbed a $1.1 million salary-cap hit when they traded Washington to the Baltimore Ravens for a fourth-round draft pick. That pushed them over the salary-cap limit and necessitated a counter move.

Releasing Rhodes saved the Raiders approximately $1.25 million in cap room.

Rhodes or fellow running back LaMont Jordan were the most logical cap casualties, especially considering the Raiders selected running back Darren McFadden with the fourth pick in the NFL draft Saturday. Jordan is due $4.7 million in base salary this season and remains likely to be released if the Raiders don’t receive a suitable trade offer in the coming weeks.

Rhodes’ departure leaves the Raiders without a proven kick returner. He was poised to replace departed kick returner Chris Carr, who signed with the Carolina Panthers.

Then again, it is conceivable that the Raiders will re-sign Rhodes between now and the start of the season. If not, fourth-round draftee Tyvon Branch likely would be tabbed to return kicks this season.

Rhodes, 29, signed a two-year, $5.5 million contract with the Raiders last season. He found playing time tough to come by upon his return from a four-game suspension for violating the league’s substance-abuse policy.

He rushed for 302 yards last season, with the bulk of that coming in Oakland’s final two games, when

Rhodes started in place of injured regular Justin Fargas.In other news, the Raiders signed the following undrafted free agents: running back Louis Rankin (Washington), tight end Chris Wagner (South Dakota State), linebackers Shane Simmons (Western Washington) and Malik Jackson (Louisville) and safety Darrick Brown (McNeese State). In addition, the Associated Press reported that the Raiders signed center Adam Spieker of Missouri.
