MotoGP has confirmed the Italian and Catalunya Grands Prix are the latest to be postponed as a result of the coronavirus pandemic.
The 2020 season has yet to begin after the calendar was decimated by the outbreak of COVID-19.
Five rounds have now been postponed, with the race in Germany and Assen TT – both scheduled for June – likely under threat too.
MotoGP said it will release a revised schedule when the global situation becomes clearer.
A statement from MotoGP read: "The FIM, IRTA and Dorna Sports regret to announce the postponement of the Gran Premio d'Italia Oakley and Gran Premi Monster Energy de Catalunya, which were set to be held at the Autodromo del Mugello from the 29th to the 31st of May and at the Circuit de Barcelona-Catalunya from the 5th to the 7th of June, respectively.
"The ongoing coronavirus outbreak has obliged the two events to be rescheduled.
"As the situation remains in a state of constant evolution, new dates for these Grands Prix, as well as the recently-postponed French and Spanish GPs, cannot be confirmed until it becomes clearer when exactly it will be possible to hold the events.
"A revised calendar will be published as soon as available."
