I see
DAC Dunajska Streda (Connor Ronan's former team)
have been expelled from the Conference League for the same reason as Drogheda. In their case, Györ of Hungary were given the one spot between them on the basis of higher UEFA ranking, with both clubs having finished fourth in their respective divisions. The owners, Vilagi, are taking their case to CAS as well. Podbrezová, who have never qualified for Europe before, are next in line for a spot, though there's a poster on the Bert Kassies forum saying that as they were kicked out after the draw had been made (they were down to play the winners or Urartu of Armenia and Neman Grodno of Belarus), a new club can't replace them and Slovakia will also only have three sides in Europe this year.
Not quite sure why the decision was taken so late though.
