Tunisia's Etoile du Sahel were held to a 1-1 draw by visiting TP Mazembe of DR Congo in the first leg of their Confederation Cup semi-final on Saturday.
The Confederation Cup holders took the lead after 19 minutes when a Hamza Lahmar free-kick found a way through the Mazembe wall.
Last year's African Champions League winners Mazembe scored an important away goal six minutes after half-time through Ivorian Roger Assale.
The other semi-final first leg on Sunday saw Algeria's Mouloudia Bejaia draw 0-0 with visiting FUS Rabat of Morocco.
The second legs will be played on Sunday 25 September.
