"His (Shirke) was the only nomination received on Tuesday," the official told PTI.
Shirke became the secretary in July after Anurag Thakur was elevated as the president with Shashank Manohar opting to quit BCCI for the ICC chairmanship.
Shirke is the supremo of the Maharashtra Cricket Association and known to be close to former BCCI and ICC president Sharad Pawar.
