Notre Dame on Sunday fired defensive coordinator Brian VanGorder after a 1-3 start that included losses to Texas, Michigan State and Duke.
Irish defensive analyst Greg Hudson will take over for VanGorder.
VanGorder, 57, is a native of Jackson, Michigan, who played linebacker at Wayne State and was later head coach of the Warriors. He also was defensive coordinator at Grand Valley and Central Michigan, among other college stops. He also has been a defensive assistant in the NFL with the Jacksonville Jaguars, Atlanta Falcons and New York Jets.
"This is a difficult decision," said Notre Dame head coach Brian Kelly. "I have the utmost respect for Brian as both a person and football coach, but our defense simply isn't it where it should be and I believe this change is necessary for the best interest of our program and our student-athletes.”
The Irish surrendered 38 points in the loss to the Blue Devils on Saturday.
They also gave up 50 to Texas and 36 to Michigan State. Notre Dame’s only win was 39-10 over Nevada.
