Williams sisters pull out
Serena and Venus Williams have pulled out of doubles at the French Open without playing a match.
The Williams sisters were supposed to compete as a pair in Paris for the first time since 2010 after receiving a wild card at Roland Garros.
But they withdrew from the tournament with no offical reason given by the French Open organisers.
Venus said she was bothered by back pain during a three-set loss in singles Sunday but Serena has advanced into the third round of singles.
They have won a total of 13 Grand Slam trophies in women's doubles, including the French Open in 1999 and 2010.
The sisters have played in only one doubles tournament this season, losing to eventual champions Sara Errani and Roberta Vinci in the Australian Open quarter finals in January.
