The start of the MotoGP season has been pushed back to 21 June at the earliest after organisers on Tuesday postponed the Italian and Catalonian Grands Prix due to the coronavirus.
The Italian MotoGP was scheduled for 31 May with Catalonia fixed for 7 June, but both have been pushed back with no new date. Last week organisers postponed the 17 May French MotoGP after previously calling off the Spanish event set for 3 May.
"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," MotoGP's governing body said in a statement.
"A revised calendar will be published as soon as available."
The Italian and Catalonia events are the latest MotoGP casualties of the coronavirus pandemic and follow the cancellation of the elite category season-opening MotoGP in Qatar on 8 March.
The next three legs of the 2020 calendar in Thailand, Texas and Argentina have all been put on ice, with Dorna, the series promoter, hoping to run them in the second half of a season which has been extended for two weeks to 29 November.
The first race of the season is now scheduled for Germany on 21 June.
