Mark Hagen and Corey Raymond have joined Indiana's defensive staff, the school officially announced Wednesday.
Hagen, a former captain for the Hoosiers, will coach the defensive tackles and serve as special teams coordinator. Raymond will coach the cornerbacks.
Hagen spent 11 seasons as an assistant at Purdue. He was a four-year letterwinner, two-time second team All-Big Ten selection, three-time Academic All-Big Ten winner and a captain at linebacker for the Hoosiers from 1987-91. He also served as a graduate and administrative assistant at IU from 1992-95, and he was a part of five bowl games, including the 1991 Copper Bowl, where he was named the bowl's Most Valuable Defensive Player.
Hagen coached the Purdue linebackers in 2006-07 and 2009-10, after working with the defensive tackles from 2000-05 and again in 2008. He served as special teams coordinator from 2003-08 and as assistant head coach under Joe Tiller from 2005-08.
"I am really excited for the opportunity to come home," Hagen said in a statement. "Coach (Doug) Wilson is in the process of putting a great staff together. There is a lot of talent in place and the opportunity to come back to IU is a unique one that my wife and I are really looking forward to. I certainly have a lot of great memories from my time as a player and working with Coach (Bill) Mallory. One other highlight is the opportunity to work with Doug Mallory, who is like a brother to me. I think it is going to be a real special situation and we are ready to get started."
Raymond, who played seven years in the NFL, spent the 2009 and 2010 seasons as the cornerbacks coach at Utah State. He worked with the cornerbacks and the strength and conditioning program the previous three years at his alma mater, LSU.
"Corey came highly recommended by Doug Mallory, Mike Ekeler, (Nebraska coach) Bo Pelini and (Utah State coach) Gary Andersen," Wilson said in a statement. "He was an excellent college player and he spent seven seasons in the NFL. Corey's off to a great start in his college coaching career and is one of the great defensive backfield technicians in the country. We are excited with the qualities he brings to our defensive staff and welcome him to our team."
