The Irish Matchplay championship has been cancelled for 2020 and the route to the World Darts Championship for the Ireland qualifier won't be known until later in the year.
The Tom Kirby Memorial Irish Matchplay also serves as a qualifying event for Alexandra Palace but that tournament, which normally attracts a field of about 140 will now not take place due to coronavirus restrictions.
Keane Barry, from Meath, won last year and went on to become the youngest Irish player ever at the World Championships, aged just 17.
For the last number of years the Tom Kirby final had taken place on the same night as the decider of the World Grand Prix, one of dart’s majors, at Citywest Hotel in Dublin.
In 2019, for the first time, it was shown live on Sky Sports.
"The annual Tom Kirby Memorial Irish Matchplay championship held in Ireland - which included the final on stage in Dublin during the World Grand Prix - has been cancelled in 2020," said the PDC.
"Details of qualifying for the World Darts Championship and World Cup of Darts from affected regions will be confirmed in due course."
The Grand Prix, won by world number one Michael van Gerwen last year, is due to take place between 4-10 October but it is still not known if it will be held in Citywest as the hotel is currently being used by the HSE "as a self-isolation facility".
The PDC says it is hopeful it will go ahead and will update at the end of this month.
Professional darts has been back up and running since last month with the Players Championship Summer Series and the World Matchplay event, which was won by Dimitri van den Bergh, being played behind closed doors in Milton Keynes.
