AUSTIN, Texas — Texas will hire Mark Hagen, Indiana's assistant defensive coordinator and defensive line coach, as the final member of Tom Herman's revamped coaching staff, a source close to the situation told Horns247.com.

Hagen, who has been recognized as a high-end recruiter, will join current Texas assistant Oscar Giles in coaching the defensive line, the source said.

Before returning to Indiana in 2016 for his second stint as a Hoosiers' assistant coach, Hagen coached at Texas A&M under Kevin Sumlin and served as defensive coordinator in the Aggies' 2014 AutoZone Liberty Bowl victory over West Virginia. He coached linebackers at A&M in 2013 and 2014, and the defensive tackles in 2015.

With Hagen's hire, Tom Herman has replaced seven of his 10-member, on-field coaching staff, including his offensive coordinator (Mike Yurcich) and defensive coordinator (Chris Ash). In addition to Hagen, Herman has a new linebackers coach (Coleman Hutzler), cornerbacks coach (Jay Valai), receivers coach (Andre Coleman) and tight ends coach (Jay Boulware).

Only Giles, offensive line coach Herb Hand and running backs coach Stan Drayton were retained from last year's Texas coaching staff.

Under Hagen at Indiana in 2018, defensive linemen held four of the top five spots on the team in sacks and three of the top five in tackles for loss, while seven recorded sacks and 10 collected TFLs.



In 2017, Indiana was No. 11 nationally (T-4th in the Big Ten) with 3.0 sacks per game and ranked 20th with 7.3 tackles for loss. In 2016, the Hoosiers were 31st in the country (5th in the Big Ten) with 2.5 sacks per game and 20th with 7.5 TFLs.

Indiana was one of three Big Ten teams (Michigan and Penn State) to rank in the league’s top five in sacks and tackles for loss per game in both 2016 and 2017.



Three linemen have been recognized by the Big Ten over the last three seasons. Robert McCray III (2017), a free-agent signing of the Kansas City Chiefs, and Ralph Green III (2016) each collected honorable-mention All-Big Ten, while Jerome Johnson (2017) claimed an honorable-mention spot on the BTN.com All-Freshman team.



The Indiana defense limited its opponents to 35.3 fewer rushing yards per game in 2016.

In his first stint as an assistant coach at Indiana, Hagen was the defensive tackles coach and special teams coordinator in 2011-12 and added recruiting coordinator duties in 2012.

Hagen coached linebackers and defensive tackles at Purdue under coach Joe Tiller from 2000-10. Hagen served as special teams coordinator for the Boilermakers from 2005-08.



A four-year letterwinner (1987, 89-91) and captain at linebacker for Indiana, Hagen was a two-time, second-team All-Big Ten selection, three-time Academic All-Big Ten member and the 1992 Big Ten Medal of Honor recipient. Hagen was a part of five bowl games, including the 1991 Copper Bowl, where he was named the bowl’s defensive MVP.

Hagen led Indiana in tackles three-straight years from 1989-91, and he was the team’s Balfour Award recipient in 1991 for bringing distinction and honor to the university. He is tied for fifth in Hoosiers history with 336 career tackles.
