Serena and Venus Williams have withdrawn from the ladies’ doubles tournament at Wimbledon.
No reason was given for their decision to pull out from a competition they have won on five occasions, most recently in 2012.
The sisters, who were easy winners in their first singles matches on Monday, could meet in the fourth round of the Championships.
In 2014 they abandoned a second-round match when an unwell Serena Williams could not complete the contest.
No reason was immediately given for Tuesday’s withdrawal, with the lucky losers Misaki Doi and Stephanie Vogt promoted to take the sisters’ place in the draw.
Both won their singles matches on Monday and they are seeded to play against each other in the fourth round.
Serena Williams fell ill during their second round doubles match in last year’s Wimbledon, forcing the pair to withdraw.
They were not the only withdrawals on Tuesday, with Slovakian pair Dominika Cibulkova and Anna Karolina Schmiedlova also pulling out of the ladies’ doubles.
The sisters have won the women’s doubles title five times, most recently in 2012. They had not begun their campaign this year.
