According to ahrahmonline, Ahly's youth football sector manager Abdel-Aziz Abdel-Shafi is expected to be named as caretaker boss of the Egyptian giants.
Ahly went down 5-3 on aggregate to the Buccaneers in Suez, Egypt on Sunday.
Under Mabrouk, the Reds failed to win any major championship this season - the first time since 2004.
Mabrouk took charge of Ahly in May after Spaniard Juan Carlos Garrido was fired following a poor run of results.
