Claire Molloy will return for the final two of Ireland's Six Nations fixtures against Italy and France next month.
The former Ireland captain took a sabbatical away from Test rugby last year to concentrate on her medical career.
But flanker Molloy, who has 69 caps, is set to meet up with Adam Griggs' squad for a two-day training camp in Abbotstown this weekend as Ireland prepare for the visit of Italy to Energia Park on Sunday, October 25 (ko 1pm).
Griggs has named a 34-strong panel, however back row pair Edel McMahon and Claire McLaughlin, as well as lock Aoife McDermott, have been ruled out of the Italy and France games through injury.
"While it’s an unfortunate setback and timing for Edel, Aoife and Claire, they are all highly motivated and diligent players who I know will get stuck into the rehab and get themselves back fit and in contention for the World Cup Qualifiers," Griggs said.
"The squad have made major strides over the last year and there is healthy competition for places.
"Each two-day camp now gives us an opportunity to focus on lifting our intensity and the quality of our training, where we will challenge the players to replicate match-like demands so that come the end of October we are ready to perform and keep the standards we set out at the start of this competition."
After the Italy game, Ireland travel to Lille to face France on Sunday, October 1.
Ireland will then face into the Rugby World Cup 2021 European Qualifiers in December, which are scheduled to be played as a single round-robin tournament on the weekends of 5th, 12th and 19th of that month.
