Tight ends coach Nunzio Campanile will serve as interim head coach for the remainder of the season, according to a statement from director of athletics Pat Hobbs.
"We appreciate Chris's dedicated efforts on behalf of our football program, our department and our University," said Hobbs. "This change is especially difficult because of the steadfast commitment that Chris and his family have made to our student-athletes. Progress has been achieved in many areas, but, unfortunately, that progress has not been realized on the field of play. As such, it is in the best interest of the program to make a change."
According to a release issued by the athletics department, Ash's and McNulty's contracts will be honored by Rutgers Athletics, exclusively using department-generated funds. Ash is owed more than $8 million.
The Ash-led Scarlet Knights are 1-3 overall and 0-2 in the conference this season. They fell to No. 20 Michigan, 52-0, on Saturday afternoon in Ann Arbor, Mich. That came on the heals of their conference-opening 30-0 loss to Iowa.
Rutgers officials have announced that a national search for a new head coach will take place.
Ash, whose contract runs through 2022, was 8-32 overall and 3-26 in the Big Ten.
Campanile is scheduled to speak at a press conference will take place Monday at noon.
Campanile will get his first chance to turn the Scarlet Knights' season around Saturday at noon against Maryland at SHI Stadium.
