The 19-year-old, who has spent the past two-and-a-half years with the Welsh outfit, has received international clearance and been registered in time for Sunday’s Premier League clash away to Derby County.
Rovers’ interim manager Gemma Donnelly was delighted to secure the holding midfielder’s signature.
“She is a tenacious, hard-working and energetic player and her arrival is massive boost to the squad, given that Kelly McLellan, Hayley O’Donnell and Felicity Middleton have all left,” she said.
Kelly, who is an international team-mate of Rovers goalkeeper Gemma Jackson, insists she had no hesitation about joining the club.
“After moving so far away from home, it will be nice to experience a new team, new players and start afresh,” said Kelly, who has represented her country in Russia, Hungary and at the European Women’s Under-19 Championship finals on home soil in August.
“Myself and Gemma (Jackson) have come through the Wales setup together and are both at Edgehill University. She is always talking about what a good setup it is here and how the club takes care of its players.
“I have only been training with Rovers for a couple of weeks, but already I can see the influence Gemma (Donnelly) and AJ (Amanda Goodwin) are having on the team. They give good advice, which the players are taking on board and putting into practice in training.”
