Referees Antonio Giannoccaro and Andrea Romeo have retired from Serie A this season.
Officials in Italy for the top flight cannot go beyond a certain age limit and both these officials are close to it, so hung up their whistles.
They are replaced in the roster of regular Serie A referees by Massimiliano Irrati of Pistoia and Dino Tommasi of Bassano del Grappa.
