The Raiders have announced they signed rookie DL Lamarr Houston, who was selected in the second round of April's draft.
Houston, the 44th overall pick, is expected to play defensive end, but he has the ability to slide inside to defensive tackle. He played tackle during his last two years at Texas.
In PFW's 2010 Draft Preview, personnel expert Nolan Nawrocki wrote that Houston is "an effective edge player who consistently makes his presence felt behind the line of scrimmage."
