Record eight-times winners Al Ahly of Egypt booked their place in the group phase of this season's African Champions League, despite a defeat in the second leg of their tie away to Ethiopia's Jimma Aba Jifar.
Ahly, who won the first leg in Egypt 2-0, fell to a shock 1-0 defeat in Addis Ababa on Sunday but progressed 2-1 overall courtesy of their home victory.
Ivorian Didier Lebri put Jimma head in first-half stoppage time, leaving Ahly to experience some anxious moments before securing a last-16 place.
Elsewhere on Sunday, Guinean club Horoya AC staged one of the greatest African club comebacks to defeat Libyan visitors Al Nasr 6-2 in Conakry - to secure a 6-5 aggregate win.
