The England women's rugby union squad will play in the World Cup in Ireland next month knowing that their contracts will not be renewed whether they successfully defend their title or not.
Reilly, Briggs, Claire Molloy and Nora Stapleton are all set to compete at their third World Cup, having been involved in both 2010 and 2014.
Currently, there are around 50 players on a mixture of full-time and part-time professional contracts but according to reports, the number of full-time contracts will be reduced to 17 after the World Cup is over and all will be for rugby sevens with the new XVs contracts due to be signed prior to the 2021 World Cup.
Coach Tom Tierney has named 28 players in his squad for the tournament which Ireland will host with Niamh briggs returning to the fold to captain the team.
Ireland will take on Australia, Japan and France in their World Cup pool with only the winners guaranteed a semi-final place.
Niamh Briggs captains the side while Ulster's Clare McLaughlin and Ashley Baxter are also included. Cronin along with Hannah Tyrrell, Katie Fitzhenry, Sene Naoupu, Baxter and Miller have all made appearances on this season's circuit of the World Rugby Women's World Sevens Series.
"While we are in a tough pool with Australia, Japan and our Six Nations rivals France, I am sure the players will rise to the occasion in front of their home fans".
Ireland's matches will be broadcast live on Eir Sport, RTE and RTE Radio.
