The Irish Open has become the latest European Tour competition to be postponed due to the coronavirus pandemic.
The event was scheduled to take place at Mount Juliet from 28-31 May, with former US Open champion Graeme McDowell acting as tournament host.
"Everyone's health is our only concern," McDowell said. "My thoughts are with everyone affected by the crisis and I hope everyone keeps safe and well during these difficult times."
Including majors and World Golf Championship events, a total of 12 European Tour tournaments have now been postponed or cancelled, while the Tokyo Olympics have been postponed by a year.
The Trophee Hassan II, which is scheduled to be held in Rabat, Morocco from 4-7 June, is now the next possible event on the calendar.
"The decision to postpone the Irish Open follows consultation with all stakeholders and was made with public health and well-being as our absolute priority," said European Tour chief executive Keith Pelley.
"We will continue to evaluate all aspects of our 2020 European Tour schedule, and discussions on the rescheduling of postponed events will remain ongoing until we have clarity on the global situation."
The US Open is due to take place at Winged Foot from 18-21 June, but the course is just five miles away from the coronavirus containment zone set up in New Rochelle, New York and non-essential businesses have been closed, putting a stop to preparations.
The R&A is still proceeding as planned to stage The Open at Royal St George's from 16-19 July and the Women's British Open at Royal Troon from 20-23 August, but is undertaking a "comprehensive evaluation" of its plans and considering contingency options.
