Oakland Raiders linebackers coach Don Martindale had a five-hour interview Saturday for the team's vacant defensive coordinator position, but sources say owner Al Davis is seriously considering naming Martindale the team's next head coach. Davis also has spoken to interim coach Tom Cable and Giants offensive coordinator Kevin Gilbride about the head coach position. Broncos quarterbacks coach Jeremy Bates and Cardinals offensive coordinator Todd Haley are said to also be on Davis's radar. And former NFL head coach Jim Fassel has expressed interest in the job.
