BOZEMAN — Ty Gregorak, who took over as the Montana State defensive coordinator in 2016, will not return to the Bobcats this fall, according to multiple sources.

Gregorak previously coached at the University of Montana, where he was the linebacker coach from 2003-09 and the defensive coordinator from 2011-15. He joined the staff at Montana State after Jeff Choate was hired to take over the program prior to the 2016 season.
