Genoa have been blocked from playing in next season's Europa League.
Genoa missed a deadline and failed to name a suitable stadium to play in.
Stadio Luigi Ferraris needs redevelopment work to meet UEFA standards, and while Sampdoria will play at Sassuolo's Mapei Stadium, their city rivals have given no alternative.
The decision means that seventh place could now offer entry to the Europa League, with Sampdoria, Inter Milan and Torino all in with a chance of attaining that spot with two games to go.
