"The Celtic Challenge provides us as a national coaching group with a window to work closely with players we’ve been tracking throughout the All-Ireland League and the recent Women’s Interprovincial Championship.
"It is an exciting group of players, combining youth and experience, and it will be invaluable for us to come together as a group for an extended period to build cohesion and connections ahead of the Six Nations campaign. We’re looking forward to the challenge over the coming weeks."
