The Raiders will keep Richard Seymour off the free-agent market once a new collective bargaining agreement goes into effect. Seymour and Oakland agreed to a two-year contract, potentially worth $30 million and containing $22.5 million guaranteed, according to an SI.com report. The defensive end, 31, went to the Pro Bowl last season, making a big impact in his second season in Oakland after being acquired in a trade from New England.
