Republic of Ireland manager Colin Bell has added Galway Women's defender Shauna Brennan to the squad to face Belgium.
The squad are set to travel to Spain tomorrow for the training camp in Murcia before facing Belgium in an international friendly at the Pinatar Arena on Sunday.
"I'm delighted to be able to bring Shauna Brennan to Spain with us," said Bell.
"She has really impressed recently in home-based training and I've also enjoyed working with her in the Women's Under-17 squad.
"She has fantastic ability and I think she'll be another player who'll really benefit from training with the senior squad. It will bring her into a different environment, training at a higher level and it's a real positive to have so many talented young players coming through.
"It is an important week for us. It is our first fixture of the year and I want to see us begin the year right as we look ahead to the start of European Championship qualifiers in September."
