Trojans athletic director Pat Haden broke the news to Kiffin after the team's arrival back in Los Angeles early Sunday morning after the 62-41 loss at Tempe, Ariz., the school said in a statement on its website.
USC has lost seven of their past 11 games dating to last year and both of their first two in Pac-12 play this season.
Kiffin's overall record in four years at USC was 28-15.
Haden will hold a news conference at USC on Sunday afternoon, the school said. The specific time and location of the event was unknown.
