World Rugby has taken the decision to postpone all international rugby matches scheduled for July because of the coronavirus pandemic.
Reigning Rugby World Cup holders South Africa had been due to face Scotland and Georgia, while England were set to tour Japan and New Zealand had been scheduled to host Wales and Scotland.
However, all of those matches, and Ireland's tour of Australia, have been postponed with no new dates set.
A statement from World Rugby read: "Extended travel and quarantine restrictions that apply to numerous countries, and concerns over adequate player preparation time, mean that any sort of cross-border international rugby competition cannot be hosted in July.
"Monitoring of the potential impact on the remaining 2020 international windows continues in collaboration with international rugby stakeholders and the respective authorities.
"All parties, including member unions, international competitions, professional club competitions and International Rugby Players, will be involved in the evaluation of potential contingency options with a view to achieving an aligned calendar for the remainder of the year.
"All decision-making will be entirely contingent on national government travel, quarantine and health advice and important player welfare and hosting considerations in line with return-to-rugby guidance recently published by World Rugby."
Rugby Australia's general manager Ben Whitaker had previously suggested that games could be rescheduled for October.
International rugby has been on hold since March when the Six Nations was halted with four matches still to play.
The financial impact of having no games has already severely impacted the unions in Australia and the USA, with World Rugby having set up a $100million relief fund.
