The marquee match between Leander Paes [Images] and Mahesh Bhupathi [Images] with their respective doubles partners has been pushed to Saturday.

The doubles schedule was thrown into disarray when Germany's [Images] Denis Gremelmayr pulled out of the tournament on Thursday with an injury in the right-hip and Juan Martin del Porto retired due to illness.

The winner of the quarter-final between Bhupathi-Mario Ancic and Paes-Aisam Qureshi, who were slated to meet Gremelmayr and compatriot Simon Greul, will thus receive a walkover into the final.

Potro, who upset Carlos Moya [Images] in the singles first round, took ill during his match against Ramon Delgado and had to withdraw from the doubles (with Juan Monaco), scheduled the same day.

The other semi-final will be between India's Rohan Bopanna-Mustafa Ghouse and Great Britain's Jamie Delgado and James Auckland, who benefited from Potro's withdrawal.
