Serena Williams' hopes of playing alongside older sister Venus in the Wimbledon doubles look in doubt after she injured her knee in her singles comeback.

The pair, who are six-time doubles champions at the All England Club, are scheduled to reunite on a Grand Slam court for the first time since 2022 on Friday.

However, 44-year-old Serena Williams might not be fit enough to play after her knee swelled up during her defeat by Australia's Maya Joint on Tuesday.

The 23-time Grand Slam singles champion did not speak to the media following the match, with Wimbledon organisers saying she was "not able to undertake" her duties.

"Serena tweaked her right knee at the end of the first set and was therefore excused from her media obligations by the Wimbledon and WTA medical teams," said Williams' agent Jill Smoller.

Andreeva suffering from the classic Roland Garros curse at Wimbledon.

Shelton out in the first round is a bit 👀

Need Cobolli to pull through and do as well as possible now ❤️

Arthur Fery kept British hopes alive at Wimbledon as he fought back from a set down to beat Finland's Otto Virtanen and reach the third round, but Katie Swan's dream return to SW19 was ended by Madison Keys.

Well done Grigor given after what happened last year, an solid four-set win over Jakub Mensik.

Mensik was so close to going out in round 1 too.

Also... it passed me by because I chose to avoid any headlines involving his name but bye bye Kyrigos

Choinski falls to Tiafoe. Fery is the sole singles survivor.

Well this is an unexpected turn of events in the Djokovic match with him an double break down in the third set.

18-year-old Iva Jovic is through to the fourth round of a Grand Slam for the second time in her career, beating Ekaterina Alexandrova 6-3 3-6 6-4.

Arthur Rinderknech takes the third set against Novak Djokovic 6-1. Still very much a match on here.

Belinda and Coco had a stormy encounter in China last year.

I wonder if they've moved on.

Order of Play for Day 6:

Serena Williams' hopes of playing alongside older sister Venus in the Wimbledon doubles look to have improved after the pair's match was added to Saturday's order of play.

Williams, 44, picked up a knee injury in her singles comeback on Tuesday, when she lost to Australia's Maya Joint.

The sisters, who are six-time doubles champions at the All England Club, are scheduled to reunite on a Grand Slam court for the first time since 2022

.

Their match against Colombia's Camila Osorio and Argentina's Solana Sierra has not been allocated a court, but organisers say it will not be played before 16:30 BST.

Novak Djokovic claimed his latest piece of history as he battled past Arthur Rinderknech to reach the Wimbledon fourth round and equal Roger Federer's men's record of most singles match wins at SW19.

After the seven-time champion produced a statement performance against former top-10 player Stefanos Tsitsipas in the second round, Djokovic had to overcome a far sterner test on his return to Centre Court.

But the 39-year-old Serb withstood an inspired resurgence from French 25th seed Rinderknech to prevail 7-5 6-4 1-6 7-6 (7-4).

Nine-time women's champion Martina Navratilova is now the only player to have won more singles matches (120) than Djokovic (105) at Wimbledon.

Victory also meant Djokovic matched eight-time men's singles champion Federer's record of Wimbledon fourth-round appearances by reaching that stage for the 18th time.

Both Swiatek and Rybakina are out of Wimbledon.

Well done Arthur Fery getting through to the second week, still the last Brit standing in the singles.
