A squad of 23 will train this weekend in Cork, while those released players will be free to play for the provinces in the Guinness Pro14.
Munster host Southern Kings on Friday.
Then on Saturday it's Leinster versus Cheetahs at the RDS, Ulster are in Wales to play Ospreys, while Connacht will also face Welsh opposition when Cardiff Blues come to Galway.
