On the place of those six teams came the V AFG champions Rakovski 2011 (South-East), Shumen 2010 (North-East), Pirin (Razlog) (South-West) and Spartak 1919 (Pleven) (North-West).
On 20 July 2012 Bdin (Vidin) canceled their participation from B PFG because of unpaid debts and unsatisfactory financial planning, which would not allow the club to survive throughout the season.
[3] On 15 February the owners of Spartak Pleven announced they were going to cancel the club's participation in the championship within the next three days due to financial difficulties.
[5] On the next day a group of around 20 fans held a protest in front of the local municipality, demanding that the city takes action to help their team.
Due to this, the club's first spring game on 2 March at home to FC Bansko was cancelled, and the rest of their season was placed under question.
[7] The Football Union confirmed its decision in a statement released on 7 March, while also cancelling Sliven's second game against Spartak (Varna) and awarding them a 3–0 win.
