Lucky Lekgwathi put the home side ahead three minutes after the half-hour mark with a superb free-kick.

The former African champions leveled in the 66th minute when Chidozie Johnson buried the ball home from the edge of the area.

The result reinforced Enyimba's lead of Group B with four points while Pirates remained second with two points.

The second tie in the group is played late on Sunday as Asec Mimosas of Ivory Coast host Ghana's Hearts of Oak.
