Death of Arizona lineman ruled accidental

TUCSON, Ariz. -- Arizona offensive lineman Zach Hemmila's death has been ruled accidental and a result of the combination of two prescription drugs.

A report released Tuesday by the Pima County Medical Examiner's Office says the cause of death was "combined toxic effects" of an opiate painkiller and an anti-anxiety medication.

The 22-year-old senior was found dead in his apartment on Aug. 8. Authorities say he died in his sleep.

Hemmila, from the Phoenix suburb of Chandler, played 13 games for the Wildcats last season. He was expected to compete for the starting center job this year.
