Stanford hired former NFL assistant Vic Fangio as defensive coordinator on Tuesday.
Coach Jim Harbaugh also announced Tuesday that Brian Polian will take over as special teams coordinator and Randy Hart is the new defensive line coach.
Fangio spent the previous 24 seasons in the NFL. He most recently was linebackers coach under Harbaugh's brother, John, in Baltimore.
Co-defensive coordinator Andy Buh left last month for Nevada. Ron Lynn will stay on as director of player development.
Polian is the son of Indianapolis Colts president Bill Polian. He coached special teams the past five years for Notre Dame.
Hart had served as defensive line coach at Washington for 21 years before holding the same job at Notre Dame last season.

Ohio State: Former star running back Maurice Clarett is again seeking early release from prison. No court date has been set. Clarett pleaded guilty in September 2006 to holding up two people outside a Columbus bar. He was sentenced to 71/2 years in prison with possible release in 31/2 years.
Pac-10: Commissioner Larry Scott said the window for expansion is open for the next year as the conference begins negotiations for a new television deal. Speaking on a conference call to introduce former Big 12 commissioner Kevin Weiberg as his new deputy, Scott talked about possibly adding new teams to the Pac-10 and launching a new TV network. Scott, the former head of the Women's Tennis Association, took over the conference last July. In his less than eight months on the job, he has seen growing interest from the membership over the possibility of adding teams for the first time since Arizona and Arizona State joined the conference in 1978. "It's really over the next six to 12 months that we'll start having serious analysis and evaluations," Scott said, adding the conference's TV deals will expire after the 2011-12 academic year. "To me, the logic if the Pac-10 is going to think about expanding, now is our window." Scott said there have been "no serious discussions" with any schools.
Cal: Sam Crosson was hired as an assistant on coach Rich Feller's staff. He replaces Matt McShane, who recently was named coach at Air Force. Crosson spent the past five seasons as the top assistant at Saint Mary's.
