The Netherlands will meet Germany and Great Britain in The Hague next week, with qualification for the Billie Jean King Cup Finals at stake.
34-year-old Rus withdrew from the squad to prioritise singles tournaments and playing for a spot at the French Open. "The Hague is my hometown, and I would love to play with the team in front of the Dutch crowd," said Rus on the website of the Dutch tennis association. "But I unfortunately have to make this choice and put my personal career above the team."
91st-ranked Rus will be replaced by Eva Vedder, who will join Anouk Koevermans, Suzan Lamens, and double specialist Demi Schuurs.
