Nebraska defensive analyst and former Iowa player Bob Elliott has passed away, according to Randy Peterson of the Des Moines Register. Iowa State, where Elliott coached as an assistant, confirmed the news.

Elliott was hired as the safeties coach at Nebraska in early 2017. He stepped down from that position on June 20 to serve in a more limited role as a defensive analyst.

According to sources, Elliott was admitted to hospice care on the evening of July 7. He’s been suffering from Polycythemia vera, a bone marrow disorder, since 1998. Elliott died Saturday. He was 64.

Elliott was born and raised in Iowa City, Iowa, and played defensive back for the University of Iowa from 1972 to 1975.
