and Belasitsa went on to win on penalties. Despite the lost playoff and the prospect of spending a second season in the regional amateur league, a number of third division teams declined participation prior to the upcoming 2011–12 season due to financial insolvency. Thus, Marek was administratively promoted to the third division, for the 2011–12 season. During the 2012–13 season, Marek finished first in the Southwest V AFG and earned automatic promotion to the Bulgarian Second Division, B PFG Marek surprised its numerous fans with a fantastic 2013–14 season in the Second Division, dominating its opponents and securing promotion to A PFG with four games to go, this returning to the top level after a six-year absence. The return to A PFG proved difficult as Marek finished the 2014–2015 season in 11th place out of 12 teams, and the team was relegated. Marek won only six games the entire season, vs. Haskovo three times, at Cherno More and vs. Slavia Sofia. After the conclusion of the 2014–2015 season, Marek did not receive a professional license from the Bulgarian Football Federation due to unpaid financial obligations to government institutions, and the team was relegated to the amateur divisions. Subsequently, Marek was fined by the Bulgarian Football Federation due to "suspicion" of match fixing and the club ownership decided to dissolve the existing club and register a new FC Marek 1915, which started competing from the lowest level of football in Bulgaria, 4th regional division, during the 2015–2016 season. Following an undefeated season, and navigating through two rounds of playoffs, Marek earned a promotion to the 3rd division for season 2016–17. After several years in the third division, Marek returned to the Second League for season 2021–2022. Despite a brave effort, Marek did not manage to secure safety in the second level, suffering immediate relegation. The team had a chance to stay in the second tier up until the penultimate round.
