Arizona senior offensive lineman Zach Hemmila was found dead this morning, UA coach Rich Rodriguez announced Monday.

UA athletic director Greg Byrne said Hemmila, 22, passed away in his sleep overnight. A cousin found him this morning. No other details were provided.

The Wildcats practiced Monday morning. The players were informed about Hemmila’s death at the conclusion of practice.

“The only thought on my mind right now is with Zach Hemmila’s family,” Rodriguez said, fighting back tears. “We lost a great young man. Everybody in our program is hurting.”

Rodriguez said he had just spoken with Hemmila’s father, Joel. He and wife Linda had been visiting in recent days.

Hemmila’s body will be examined Tuesday, said Dr. Gregory Hess, chief medical examiner for Pima County. Results of those tests are expected in 4-6 weeks.

“That’s about all we know right now,” Hess said.

Hemmila, who played at Chandler High, was entering his fifth season and was the favorite to start at center. He started six games at left guard last season.
