Both Serie A games scheduled for Saturday evening have fallen foul of inclement weather, while Sunday's programme has also been disrupted.
Heavy snowfall and freezing temperatures across Italy have forced the postponement of Bologna's match against Atalanta and AC Milan's fixture at Fiorentina as conditions for fans were deemed unsafe.
The matches will now be played in the New Year after the possibility of playing them on Sunday was ruled out by the Italian Football League.
"The Lega Calcio, given the continuation of the exceptional wave of bad weather that has hit the cities of Bologna and Florence, has found it impossible to set alternative dates in the coming days - due to the start of the winter break - and so has ordered the postponement of these matches until a later date," read a statement from Lega Calcio.
Shortly after the announcement, Sunday's match between Udinese and Cagliari also fell victim to the weather and will now have to be rearranged, while some of the other remaining Week 17 matches could also be at risk of being called off.
It isn't just the top-flight that has been affected by the adverse weather as four matches in Serie B; Cittadella-Ancona, Mantova-Crotone, Sassuolo-Salernitana and Triestina-Piacenza; were cancelled this afternoon, along with a host of matches from the lower leagues.
