The Czech Republic has rested Radek Stepanek and chosen Jan Hajek and Lukas Rosol to try to give the Davis Cup defending champions a good start against host Kazakhstan in the opening singles of their quarterfinal on Friday.
The Czechs are already without injured world No. 6 Tomas Berdych, while Stepanek, who earned the winning point in the final against Spain last year, is coming back from neck surgery in January and unable to play all three days on the indoor clay-court.
Stepanek was drawn on Thursday for Saturday's doubles.
Hajek will open the tie against Mikhail Kukushkin, followed by Rosol against Andrey Golubev.
The winner will play either Argentina or France in the semifinals in September.
