Northwestern senior linebacker Chris Jeske has decided to end his playing career after battling injuries for four seasons.
Jeske will serve as a student assistant coach this year and remain with the team throughout training camp. A heralded recruit out of Joliet, Ill., Jeske battled back problems that eventually required surgery and also tore his ACL and his meniscus.
He made it through spring ball and practiced last week before the back problems became too much to overcome. It's a very tough situation for Jeske, who came to Northwestern with high hopes and worked extremely hard to overcome injuries. He appeared in three games last year, mostly on special teams.
