The Raiders continued to shape their roster Saturday, claiming cornerback Phillip Adams, linebacker Keenan Clayton and tackle Willie Smith off waivers.

Adams has seen time with the San Francisco 49ers, the New England Patriots, and most recently, the Seattle Seahawks. Though he’s never started an NFL game, Adams has recorded 11 tackles and one interception.

Clayton spent the past two season with the Philadelphia Eagles, who drafted him in the 4th round of the 2010 NFL Draft. He played in 21 games making one start and 18 tackles.

Smith might be the most intriguing of the additions. In his three starts for the Washington Redskins, Smith faced off against Jason Pierre-Paul, Jared Allen, and Trent Cole, three of the best pass rushers in the league. Only Cole and Allen recorded sacks against Smith, an impressive feat for the undrafted rookie out of East Carolina.

To make room on the 53-man roster, the Raiders waived cornerback Chimdi Chekwa, the Raiders’ fourth round selection in the 2011 Draft, cornerback/return specialist Bryan McCann, and waived/injured defensive tackle Jamie Cumbie. Only Chekwa and Cumbie have practice squad eligibilty.

As it would happen, the Raiders have practice squad availability. The Raiders have announced the additions of  linebacker Kaelin Burnett, wide receiver Brandon Carswell, wide receiver Travionte Session and linebacker Nathan Stupar to the practice squad. The Raiders can have up to eight players on their practice squad.
