Cal reportedly has interviewed Louisiana Tech coach Sonny Dykes, while another potential candidate has taken his name out of the running.
Meanwhile, Gary Andersen said he is staying at Utah State, after being mentioned as a candidate at Cal and Colorado.
Dykes has a history in the Pac-12, having served as offensive coordinator at Arizona during Mike Stoop's tenure. The Wildcats' offense thrived under Dykes in 2007-2009.
Dykes has already interviewed for the coaching opening at North Carolina State.
Dykes is 22-15 in three seasons at Louisiana Tech and had the Bulldogs ranked as high as No. 19 during the 2012 season.
In Anderson's fourth season at Utah State, the Aggies (10-2, 6-0 WAC) set single-season records for wins (10) and earned their first outright WAC title since 1936.
