Just a day after 36-year-old Venus, suffering from a virus and stomach complaint, was beaten in the singles, the top-seeded sisters slumped to a 6-3, 6-4 defeat against the Czech pair.

The sisters won the Olympic doubles title in 2000, 2008 and 2012.

Serena is the defending champion in singles while Venus was the title winner in Sydney 16 years ago.
