World Rugby has confirmed that a final decision on adjustments to the global calendar for 2020 will be made by a vote on 30 June.
It follows Monday's World Rugby Professional Game Forum meeting which was attended by stakeholders, including Ireland, the Pro14 and the British and Irish Lions, who discussed plans to complete the domestic and international seasons affected by the coronavirus pandemic.
Progress was also made on the long-term redrawing of the global calendar, with plans progressing to replace summer Tours with a longer Autumn block of Tests.
The hope is to better align the seasons in both hemispheres, while providing more clarity in fixture planning for club and Test competitions.
"There was commitment to further detailed commercial and player welfare modelling in full collaboration with the club game to better assess the viability and attractiveness, for all parties, of a potential new ongoing global release period of October/November from 2021, replacing the July window," said the World Rugby statement.
In the short-term, the governing body have work to do in agreeing a satisfactory conclusion to the truncated 2019-20 season, with the Guinness Six Nations unfinished, as are most domestic and European competitions.
"With the global Covid-19 pandemic significantly impacting the 2020 rugby calendar and union and club finances, all parties recognised the need to agree a compromise solution that enables both disrupted professional club and international competitions to be completed this year," World Rugby said.
"In the absence of full alignment, further information sharing and discussion will be undertaken with all parties regarding the viability of proposed adjustments to the 2020 international release weekends stipulated in Regulation 9 that will enable postponed and other international matches to be played in an adjusted window from October, whilst enabling the completion of existing club competitions.
"The final decision on 2020 will be confirmed by vote of the World Rugby Council on 30 June following consideration and recommendation by the World Rugby Executive Committee."
In Ireland, club rugby matches will be permitted to be played in September as part of the IRFU's Return to Rugby programme.
If the Pro14 season does resume, competition board member and Scottish Rugby Union chief operating officer Dominic McKay had predicted a "curtailed end" to the suspended campaign, depending on government approval from stakeholder nations.
