Oregon State offensive line coach Mike Cavanaugh turned down an offer to become USC’s offensive line coach, according to sources.

Cavanaugh was offered the job last weekend following an interview with USC coach Lane Kiffin. Current offensive line coach James Cregg will probably switch to tight ends next season.

It was unlikely Cavanaugh would leave Oregon State especially when Kiffin might be fired after next season. Oregon State offensive coordinator Danny Langsdorf donated a kidney to Cavanaugh’s wife in 2007.

Sources said former USC assistant coach Kennedy Pola and the university are working out a financial settlement following his dismissal last week. One possible scenario to replace Pola would elevate quarterbacks coach Clay Helton to offensive coordinator and continue to allow Kiffin to call plays.

Kiffin could not be reached for comment Monday.
