Sabeur Ben Frej scored from the penalty spot in the 70th minute to give Etoile Sahel a precious victory.

Armed Forces' Nouredine Kacemi was sent-off just before the break for making a harsh tackle as the Moroccan hopes to grab a victory suffered a blow.

Ten minutes from time, substitute Idrissi Youssef Kaddioui followed Kacemi on the sidelines for elbowing an opponent from behind.

Etoile Sahel are joint leaders in Group A with Ittihad of Libya, who stunned Algeria's JS Kabylie.
