Nebiolo, 76, who supervised the transition from amateurism to professionalism in the primary sport of the Olympic Games, died in Rome on November 7.
Diack, 66, the senior IAAF vice-president who automatically assumed the presidency, said this week he would like to continue as the federation's chief and his position will be the main topic of discussion at the IAAF council's two-day meeting in the federation's Monaco headquarters on Thursday and Friday.
IAAF officials said the council would consider how long Diack's interim presidency would continue and whether the position would need an immediate vote by the federation's congress comprising representatives of the individual federations.
They said a postal vote was possible or the council could convene a congress at one of the two major events next year, the world cross country championships in Portugal in March or the Olympic Games in Sydney six months later.
