Caf released a press statement after Tunisian club Esperance complained about Al-Ahly's behaviour in the first leg.
Al-Ahly won the game 3-1 thanks to two controversial penalty decisions and their player Walid Azarou was specifically accused of unsporting behaviour.
The suspension has come after Esperance released a complaint on the weekend. The Tunisian club asked Caf to suspend Azarou from the second leg as they alleged that the Al-Ahly striker assaulted one of their players.
