Leinster and Ulster are set to resume their Heineken Champions Cup campaigns in mid September.
The EPCR have confirmed they are planning to restart the 2020 tournament on the weekend of September 18th, 19th and 20th.
Leinster are set to host Saracens in the last-8, while Ulster will be away from home against Toulouse.
The semi finals will take place one week later, with the decider set for Marseille on Saturday October 17th.
The venue for the final remains unclear though, with the EPCR saying it will be reviewed in line with potential travel restrictions.
It's also been revealed that a 24-team tournament is being considered for the 2020/21 season, which will get under way in mid-December.
