A former star offensive lineman for the Iowa Hawkeyes was killed when he was struck by a train while jogging near Tucson, Ariz. on Saturday (July 2, 2016).

Iowa athletic officials confirmed the death of Kyle Calloway, 29. Funeral arrangements are pending.

“We are all stunned and very saddened to hear of the tragic accident claiming the life of Kyle Calloway,” said Iowa coach Kirk Ferentz. “Our heartfelt condolences and prayers go out to Kyle’s family and to those who knew him. He was a valued and respected member of our program.”

Calloway was a member of the Iowa football program from 2005-09, redshirting his first year. He joined the Hawkeyes from East High School in Belleville, Ill., where he had participated in football, basketball, and track.

Calloway started 37 of his final 38 games as a Hawkeye, including the final 12 games as a senior in 2009. Iowa posted an 11-2 record in his final season, and he started at right tackle in Iowa’s 16-9 win over Georgia Tech in the 2010 Orange Bowl. The Hawkeyes were ranked seventh in the final rankings.

Calloway started all 13 games in 2008, including a 31-10 win over South Carolina in the 2009 Outback Bowl.

Calloway, who played primarily right tackle, earned second team All-Big Ten honors as a junior and senior. He was selected for the East-West Shrine Game following his career. Calloway was drafted by the Buffalo Bills in the sixth round of the 2010 NFL Draft.
