Casey Dellacqua will step into the Fed Cup singles arena for Australia after an injured Sam Stosur was forced to remain on the sidelines.

Stosur is suffering an Achilles injury, meaning Dellacqua will head onto the court in the singles rubber against the Netherlands’ Arantxa Rus.

Australian captain Alicia Molik told 7TWO that Stosur’s Achilles has been an issue all week, and that Dellacqua had been prepared for the potential call-up.

Jarmila Gajdosova will open Australia’s campaign in the opening rubber against Dutchwoman Kiki Bertens.
