Defending champions Leinster will host their rivals Munster in the Guinness PRO14 at the Aviva Stadium on the evening of Saturday August 22nd.
Connacht are set to take on Ulster on the following day at the same venue with the northern province taking on Leinster a week later and Munster facing Andy Friend's westerners.
All four of those inter-pro derbies are likely to take place behind closed doors, with the government currently limiting attendances at outdoor events to 200 people.
The regular section of the PRO14 season will come to end after those two rounds of games, with organisers cutting the campaign from 21 to 15 matches.
