Thunder have signed Ireland international Laura Delany for their final four Rachael Heyhoe Flint Trophy matches.
The 30-year-old allrounder replaces Deandra Dottin, who has returned to the Caribbean to represent Trinbago Knight Riders in the CPL.

While she cannot match Dottin's explosivity, she has scored 2,868 runs at 30.51, including three centuries and 15 half-centuries, and picked up 84 wickets with her leg-spin bowling across her List A career.
Thunder currently sit sixth in the Rachael Heyhoe Flint Trophy and trail third-placed South East Stars by nine points.
Regional director of women's cricket, David Thorley, said: "I would like to thank Deandra for her efforts this summer. Her experience has helped us greatly both on and off the field and we wish her well in the CPL back home.
"Once we realised that we would be without Deandra for the final four 50-over matches of the season, we felt it was important to replace her experience and run-scoring ability in the middle order and we feel that Laura fits the bill perfectly.
"After captaining her country for over seven years and making almost 150 appearances on the international stage, Laura will bring vital experience to our squad and we hope that her contributions on the field will help us to finish the season strongly."
