Southern California defensive end Armond Armstead has been released from a hospital after spending five days in care for an undisclosed ailment.

USC coach Lane Kiffin says Armstead left USC University Hospital on Tuesday.

Kiffin says the senior will return to class, but won't be back in conditioning drills with the Trojans until more medical tests are completed.

Armstead was hospitalized last Thursday for a battery of medical tests. The school and Armstead's family haven't disclosed the reason.

Armstead made 43 tackles with three sacks last season. The Sacramento native decided in December to return for his senior season, when he's expected to start at defensive end for the Trojans.
