USC head football coach Steve Sarkisian was officially fired today, athletic director Pat Haden said in a statement.

The move comes one day after Sark was put on indefinite leave after showing up "in no condition to lead practice" on Sunday.

Haden said he was concerned for the health of the USC coach. Sarkisian said he would seek help to see if he had an alcohol problem after he appeared intoxicated at a donor event in August.

Offensive coordinator Clay Helton has been named interim coach of the 3-2 USC Trojans.
