During season 2012-2013 OFC Sliven 2000 was suspended due to their inability to field at least 7 players in their senior team and was relegated finishing last in the group.
The four V AFG champions - Botev Galabovo (South-East), Dobrudzha Dobrich (North-East), Marek Dupnitsa (South-West) and Akademik Svishtov (North-West) - were promoted to B PFG because of their standings in their places in their respective groups the previous season.
Further, the football union was still awaiting word from Minyor Pernik on whether they will be able to participate in the group, because of speculations in the media of their inability to cover their financial costs for B PFG for the whole season.
On a special meeting on 1 August 2013 BFU approved the filed decisions by Svetkavitsa Targovishte and Chavdar Etropole, and gave final notice to Minyor Pernik to sign the required 7 players at least.
The same day the leadership of Minyor Pernik declared that they will abolish the current club and intend to found a new one, which will take a license to participate in the third division (V AFG) of the Bulgarian football system.
