Leinster and Ulster's European Rugby Champions Cup quarter-finals have been postponed due to the coronavirus outbreak.

Leinster were due to face defending champions Saracens at the Aviva Stadium on 4 April, with Toulouse hosting Ulster the following day.

Both games, along with the other Champions and Challenge Cup quarter-finals, have been suspended by tournament organisers following a conference call on Monday.

The Pro14 season has already been suspended indefinitely while Ireland's summer tour of Australia is also in doubt.

A statement read: "The board of European Professional Club Rugby (EPCR) has decided that this season's Heineken Champions Cup and Challenge Cup quarter-final matches will not now be played on the scheduled dates of 3/4/5 April.

"Amid growing public health concerns due to the COVID-19 pandemic, the decision was taken during a conference call today (Monday, 16 March) to postpone the eight matches on the weekend in question and to suspend the European club rugby season.

"While respecting all further directives by governments and local authorities, EPCR, in conjunction with the relevant leagues and unions, remains committed to trying to find a solution which will enable it to complete the 2019/20 Heineken Champions Cup and Challenge Cup tournaments at such a time as that aligns with preventative measures undertaken by an overwhelming majority of sport’s governing bodies and tournament organisers in Europe.

"EPCR’s priority is the health and welfare of players and club staff, and an update regarding the knockout stages of the tournaments will be communicated to all stakeholders as soon as practicable."
