Former Esteqlal keeper Hadi Tabatabaii saved the spot-kick, but Hedayat Mombeyni awarded Saipa another chance for the goalie's wrong standing position.
Qandi newly appointed manager Majid Jalali said he had watched the video several times and there was nothing wrong with Tabatabaii's position.
The veteran trainer said the referee even admitted the keeper had done nothing wrong, but he relied on his linesman's judgment.
