Former 49ers defensive coordinator John Marshall emerged Tuesday as the first known candidate to replace departed Raiders defensive coordinator Rob Ryan.
Marshall is expected to interview with the Raiders as soon as today, a person close to Marshall confirmed.
"We continue to have prospective coaches coming in for visits," Raiders senior executive John Herrera said, without denying or confirming Marshall's interview.
Marshall was the Seattle Seahawks defensive coordinator the past three seasons. He spent the 2003-05 seasons as the team's linebackers coach.
He's been a defensive coordinator for four NFL teams — the Atlanta Falcons (1983-85), the 49ers (1997-98), the Carolina Panthers (1999-2001) and the Seahawks.
Marshall's Seattle tenure ended with the promotion of Jim Mora to coach.
The Raiders continued the rebuilding of their coaching staff in advance of naming a head coach by hiring former Seahawks defensive line coach Dwaine Board to handle the same role with the Raiders.
Board, a former defensive end with the 49ers, spent the past six seasons with the Seahawks. He, too, was part of coaching staff purge by Mora earlier this month. He replaces Keith Millard, who spent the past four seasons with the Raiders and is being considered for a position on the Green Bay Packers staff.
The Raiders also moved closer to filling the linebackers coach vacancy created by the departure of Don Martindale.
They didn't have to look far to find an attractive candidate. Raiders managing general partner Al Davis called upon Concord native Mike Haluchak about the prospect of joining the Raiders. Haluchak, 59, owns an extensive coaching background. He has coached linebackers the past 30 years. The past 23 seasons were spent in the NFL, including the past four with the Cleveland Browns.
In other news, Darren Perry joined the Packers as their safeties coach. He spent the past two seasons as Oakland's defensive backs coach. He was replaced earlier this month by former Packers coach Lionel Washington.
Also, Raiders advance scout Paul Hackett is being considered for the quarterbacks coach spot handled by John DiFilippo the past two seasons, a person familiar with the process said. Hackett joined the Raiders last season. He has an extensive history of working with quarterbacks and is credited with recommending quarterback Rich Gannon to the Raiders in 1998.
