Two minutes into the second half, Sumayhan Al Nabit opened the scoring with a deceiving low strike into Rashid Mazaheri’s net.
Shahriyar Moghanlou levelled the scoreboard in the 65th minute.
The result leaves the Buraidah-based side in second place on seven points behind Al-Duhail SC who had emphatically beaten Pakhtakor FC earlier, while Sepahan will need to win their next two games to have a chance of snatching the automatic knockout stage ticket as it sits in third place on four points.
