The players, both from the same team, were subsequently taken out of the draw which began on Sunday.
The unknown pair will be replaced by the first team on the alternate list.
“Since the start of the tournament on May 24, 2,446 tests have been carried out on the players and their teams,” read a statement from the tournament organizers.
“This is the first time that tournament organizers have had to withdraw players, in accordance with their health protocol.
“As a reminder, the health of all players in the tournament and that of their teams is constantly monitored through very regular testing, and they live and train in socially distanced ‘bubbles’.”
This year’s tournament was slated to start a week earlier, but has been postponed to allow a limited number of fans to watch. This comes just seven months after the last edition which was postponed to September 2020 amid the pandemic.
On the pitch, top players Serena Williams, Daniil Medvedev, Stefanos Tsitsipas and Alexander Zverev all advanced to the next round on Wednesday.
