Inter's game against Sampdoria and two other Serie A matches have been postponed following the recent coronavirus outbreak in Italy.
At a news conference, Italian prime minister Giuseppe Conte confirmed Sunday's fixtures in the Lombardy and Veneto regions, including the Hellas Verona-Cagliari and Atalanta-Sassuolo clashes, would not go ahead.
The move comes as part of preventative measures against the spread of the coronavirus, officially named Covid-19, after two people died and dozens more reportedly tested positive.
Saturday's scheduled Serie B match between Ascoli and Cremonese was earlier postponed and up to 88 amateur football matches were also called off, according to Italian news agency ANSA.
In a short statement, Inter announced only that their meeting with Sampdoria at San Siro was postponed "to a later date".
The third-placed Nerazzurri sit six points behind Serie A leaders Juventus, who won 2-1 against SPAL on Saturday.
Sunday's three other games are expected to go ahead as planned.
Genoa are due to host title-chasing Lazio, with Torino to face Parma and Roma entertaining Lecce.
