NAPA -- Free agent Pro Bowl linebackerdefensive end Andre Carter worked out for the Raiders Tuesday and if the team deems him healthy and able to contribute, he could address a need as a pass-rushing specialist.Carter, the No. 7 overall pick of the 2001 draft by the 49ers out of Cal, is coming off his first Pro Bowl season, having finished with 10 sacks in 14 games last year for New England. He declined to comment, though, when approached by reporters after his workout, which was overseen by general manager Reggie McKenzie."I've got to stay low key," Carter said with a laugh. "If it works out, God willing."Carter, 33, missed the final two games of last season with a torn left quadriceps. Before that, though, he set the Patriots' single-game record with four sacks against the New York Jets' Mark Sanchez on Nov. 13.The Raiders are a 4-3 base defense team and while Carter has played primarily in 3-4 schemes in his career, which encompasses five seasons in San Francisco, five more in Washington and one in New England, the Raiders have shown flashes of the 3-4 thus far. Plus, they promise to be more flexible in schemes and, well, they don't have that tried and tested sack-happy player on the roster. Not with Kamerion Wimbley and his 16 sacks the past two years now in TennesseeCarter has 76 sacks in his career; current Raiders career sack leader defensive tackle Richard Seymour has 54 12 career sacksin the same number of seasons as Carter. In fact, Seymour was drafted by New England one spot ahead of Carter."We're going to shake all the bushes and see what falls out," said Raiders coach Dennis Allen, "and if we feel like we've got something that can help us, we're going to do it."
