"Stanford co-defensive coordinator and Foothill High product Jason Tarver is under consideration to be the defensive coordinator of the Raiders, a person familiar with his candidacy confirmed Saturday.

Tarver, 37, worked one year as the co-defensive coordinator under David Shaw after working for the 49ers from 2001 through 2010 as an offensive assistant, a running backs coach and an inside linebackers coach.

First reported by ESPN's Adam Schefter, Tarver's presence in coach Dennis Allen's search for someone to take over his defense does not present the roadblocks inherent in the process when attempting to seek out candidates from NFL teams.

It's been slow going for Allen so far.

One of the candidates the Raiders reportedly interviewed, Greg Manusky, became defensive coordinator of the Indianapolis Colts.

Among those whom the Raiders reportedly sought permission to interview and were denied include Denver linebackers coach Richard Smith and New Orleans defensive assistant Bill Johnson."
