LOS ANGELES -- Southern California fired Steve Sarkisian on Monday, one day after the troubled football coach was put on leave.
Athletic director Pat Haden made the move one day after determining Sarkisian showed up at school in no condition to lead practice, although Haden refused to reveal specifics about the coach's condition. Offensive coordinator Clay Helton was appointed interim coach Sunday.
USC hasn't elaborated on Sarkisian's problems, but the second-year coach had an embarrassing public display in August at a pep rally where he appeared to be intoxicated while giving a speech. Sarkisian later apologized and said he had combined alcohol and medication, but promised not to drink again during the season.
Sarkisian's unsteady appearance Sunday prompted Haden to make the program's fourth coaching change in just over two years.
"After careful consideration of what is in the best interest of the university and our student-athletes, I have made the decision to terminate Steve Sarkisian, effective immediately," Haden said in a statement.
"I want to add how proud I am of our coaching staff and players and the way they are responding to this difficult situation. Through all of this we remain concerned for Steve and hope that it will give him the opportunity to focus on his personal well-being."
Helton, Sarkisian's offensive coordinator, will officially lead his first practice Tuesday as the Trojans (3-2, 1-2 Pac-12) prepare for their annual rivalry game at No. 14 Notre Dame.
Sarkisian went 12-6 at USC, where he started as an assistant coach under Pete Carroll with the program's dominant teams of the past decade.
