The Raiders brought in USC quarterbacks coach Steve Sarkisian for a second interview Wednesday as the team intensified its search for a new head coach. Sarkisian, the first candidate to interview after Art Shell was fired, met again with owner Al Davis and other team executives, a person in the league with knowledge of the search said on condition of anonymity. The person requested anonymity because the Raiders are not releasing any details about the search. Sarkisian didn't immediately return a message seeking comment.
