Raiders claim Keenan Lambert, pass on Craig Dahl

For the second straight waiver claim Sunday, the Oakland Raiders have picked up a young defensive player from the defense-rich Seattle Seahawks.

Addressing their thin safety group, Oakland claimed Keenan Lambert. He is an undrafted rookie form Norfolk State. Lambert also is the half-brother of Seattle star safety Kam Chancellor. Lambert was hurt during much of training camp and only played in two preseason games, including the preseason finale against Oakland. He had five tackles in that game.

The Raiders considered signing veteran safety Craig Dahl. According to a source, he took a physical with Oakland on Sunday, but the team is not signing him at this time. Perhaps Oakland will reconsider signing Dahl in the coming weeks.

The Raiders cut undrafted rookie cornerback SaQwan Edwards to make room for Lambert. Edwards should be a candidate for the practice squad if he clears waivers Monday. No Oakland player was claimed Sunday, so players like defensive linemen Max Valles and Shelby Harris are candidates for Oakland’s practice squad, which can be announced Sunday. Quarterback Garrett Gilbert has joined Oakland’s practice squad, agent Leigh Steinberg announced. Gilbert, a former SMU star, was with Detroit.

Meanwhile, rookie tight end Clive Walford is back to practice Sunday after missing three weeks after re-aggravating a hamstring injury. This is just the third practice since the start of training camp for Walford, a third-round pick. It may take some time for him to get caught up on the offense. Oakland backup receiver Andre Holmes also practiced Sunday. He missed a couple of weeks with a broken hand.

New England signed receiver Kenbrell Thompkins to the practice squad, according to NFL Media. Oakland cut him this week. He was claimed from the Patriots last year.
