Relegation Play-Off
The last two teams (teams ranked 13th and 14th) from each group (total 4 teams) should have relegated to 3rd Division - 2nd Stage. But due to direct relegation of Shahr Khodro (Omid Vahdat) Mashhad from 1st division (Azadegan League) to 3rd Division - 2nd Stage (instead of 2nd Division), one fewer team would relegate from 2nd Division. Therefore, Relegation Playoff between 13th-placed teams has determined the relegated and remained team in 2nd Division.[9]
