Kerr was hired by Dorrell in January of 2003, having previously served as defensive coordinator at Colorado State under coach Sonny Lubick.
Head coach Karl Dorrell said "This was a very difficult decision for me to make. Larry is a fine coach and did a good job helping us build our foundation. But at this time, i felt it was in the best interest of the program to make a change.
Dorrell will begin the search for a new defensive coordinator immediately.
