1.^Iraklis Thessaloniki withdrew from the league because of Financial Problems. The Founding Club (Athlitiki Enosis Pontion Katerini) stopped to exist too. The Original Gymnastikos Syllogos Iraklis will decide if a new Football Team will start from The Third Category of the Local Championship Macedonia Football Clubs Association, or if The Football Team Of G.S. Iraklis will be merged with 1st category (A1) Macedonia Football Clubs Association club Iraklis Ampelokipi, as it happened before 5 years with Athlitiki Enosis Pontion Katerinis F.C.. The club was therefore automatically disqualified from the tournament.
