"My heart and the heart of the Purdue family is saddened by the loss of Doug Davis," head football coach Darrell Hazel said. "He will surely be missed. He was a great man, who worked tirelessly to make people better. Our thoughts and prayers go out to his family."
Davis joined the Boilermaker staff in 2013. He came to Purdue after spending the 2011 and 2012 seasons working with Hazell at Kent State. From 2007 to 2010, Davis was a strength assistant at Ohio State University, where Hazell was the wide receivers coach.
Prior to his stint at Ohio State, Davis was a strength and conditioning coach at the University of South Florida.
