SANTA CLARA, Calif. — Scott Linehan is in his second interview with San Francisco coach Mike Singletary and general manager Scot McCloughan, hoping to become the 49ers' offensive coordinator.

Linehan is the first candidate to get a second interview in Singletary's quest to replace Mike Martz, who Singletary fired last month. The 49ers are looking for their seventh offensive coordinator in seven seasons.

Linehan was fired four games into his third season as the St. Louis Rams' head coach last September, but the veteran assistant has been a successful offensive coordinator in Miami and Minnesota.

Singletary also has interviewed Indianapolis receivers coach Clyde Christensen, Cleveland offensive coordinator Rob Chudzinski and Denver offensive coordinator Rick Dennison.
