Enyimba will have a mountain to climb to reach the semifinal of the CAF Confederation Cup after they were held to a 1-1 draw at home by Horoya AC of Guinea today.
The return leg in Conakry will be played on next Sunday with Horoya having a goal on the road in the bag.
Enyimba went in front after 19 minutes through Austin Oladapo, who fired an unstoppable shot from well outside the box.
However the visitors drew level on 71 minutes through Boniface Haba, who headed home a cross from the right past Enyimba goalkeeper Theophilus Afelokhai.
Nigerian forward Bolaji Sakin started for Horoya.
Both teams carved chances to have won the game, but there wasn’t going to be a winner in Aba.
