Club rugby will be organised on a provincial basis until the turn of the year, with the Energia All Ireland League due back on January 9.
efore then, clubs will compete in the Community Series within their own provinces as the IRFU look to limit travel and curb exposure to covid-19 when rugby returns.
The 2019/20 season was abandoned in March and the four men's divisions will return as they were when the all-island competition gets underway after Christmas.
The union has put in place contingencies around the virus, stipulating that "where the presence of COVID-19 in a club forces the cancellation of a match in Stage 1 or Stage 2, the result shall be declared a draw and teams will be allocated two match pointseach and no score registered. No bonus points will be awarded."
The conferences will be decided on a league format, with matches running from September 26 to December 11 and the top teams will progress to the Bateman Cup which will be held after Christmas.
The regular season will then take place over nine weekends with one round of fixtures across the 10-team divisions, with semi-finals and finals at the end of the campaign, and no relegation.
Women's teams which are not part of the All Ireland League will be invited to take part in the pre-Christmas tournament, with Galwegians currently the only side from Connacht and two each from Munster and Ulster.
Meanwhile, the union has confirmed that the country's academy players will return to training on July 20.
With the Celtic Cup cancelled due to Covid-19, the four provinces will play a series of A fixtures in late September and early October, while there will also be three interprovincial Sevens tournaments in the same period.
