  1. 'Oh my God' - Federer shock at Williams retirement

    Katie Falkingham
    BBC Sport at Wimbledon

    Roger Federer has just been told about Serena Williams' retirement through injury in his news conference, having watched his opponent Adrian Mannarino do the same after also slipping.

    "As I was walking out, the referee asked me how I was feeling about the court. I said, 'I think the court plays normally as we know it'," said Federer.

    "I do feel it feels a tad more slippery maybe under the roof. I don't know if it's just a gut feeling. You do have to move very, very carefully out there. If you push too hard in the wrong moments, you do go down.

    "I feel for a lot of players, it's super key to get through those first two rounds because the grass is more slippery, it is more soft. As the tournament progresses, usually it gets harder and easier to move on.

    "This is obviously terrible that it's back-to-back matches and it hits Serena as well. Oh my God, I can't believe it."

  2. *Pouille 5-5 Norrie

    A great serve from Cameron Norrie out on court two and that's a big hold when he was two points away from losing the set. But it's 5-5, still up for grabs.

  3. Murray's next opponent is set

    German qualifier Oscar Otte has become just the second man to win a final-set tie-break at Wimbledon - he's prevailed 4-6 6-3 6-2 6-7 (5-7) 13-12 (7-2) against Frenchman Arthur Rinderknech.

    Up next for him? Andy Murray, a match which would normally be scheduled for tomorrow but we wait for confirmation on that.

    Otte resumed his match today after they had to stop at 9-9 in the final set last night.

  4. Pouille 5-4 Norris*

    A punch of the air from Cameron Norrie as Pouille sends one wide at 15-30, two points from the first set.

  5. Pouille 5-4 Norrie*

    British number two Cameron Norrie is serving to save the first set and he's 5-4 down against Lucas Pouille of France, but it's still on serve.

    Unless it gets moved, it's not going to be finished tonight.

  6. 'So sad for Serena'

    Aliaksandra Sasnovich, who moves into the second round as Serena Williams has to withdraw becuase of an injury, says: "Such a nice atmosphere to be here.

    "It's the first time for me to play on Centre Court and I am so sad for Serena - but all the best for her.

    "I love the grass, I like English people, the public I want to stay here as long as possible and make you happy."

  7. Elsewhere...

    *Pouille 3-3 Norrie

    Katie Falkingham
    BBC Sport at Wimbledon

    Away from the Centre Court drama, Britain's Cam Norrie is in action over on Court Two.

    His match with Lucas Pouille is currently on serve at 3-3 in the first set.

    It will be a race against the light to get this one finished...

  8. 'Extremely slippy out here'

    Andy Murray, who played on Centre Court yesterday, posts on Twitter...

    Monty Moncrieff: Absolutely gutted that Serena has had to retire in her opening match. Any goodbye after that injury would be tough but that looked like a possible career farewell to #Wimbledon (I hope not)

  10. 'A last goodbye?'

    Is this a last goodbye? This is a difficult watch.

  11. 'It was a rollercoaster match'

    Struff 4-6 1-6 6-4 6-7 (3-7) Medvedev

    Here is Daniil Medvedev: "I was a bit surprised by the first two sets that I managed to win so easy, that's why Grand Slams are funny - I thought 'I got it, just stay focused', and he turned it around and there was so many opportunities for both of us.

    "Until the last set it was not over. It was a rollercoaster match but happy to go through."

  12. Struff 4-6 1-6 6-4 6-6 (3-7) Medvedev*

    John McEnroe
    Three-time Wimbledon singles champion on BBC TV

    If people didn't know about Medvedev, they're going to find out a lot more very quickly about why he is deserving of that number two seed.

    Struff is a tough customer, he made this interesting and much more stressful for Medvedev than you would have expected.

  13. 'Can't believe the emotion she's going through'

    Annabel Croft
    Former British number one on BBC Radio 5 Live Sports Extra

    The work that she's put in to try and win this elusive 24th title - I just can't believe the pain and emotion she's going through right now.

  14. game, set and match

    Game, set and match - Sasnovich. Serena Williams retires through injury

    Sasnovich 3-3 S Williams (retires because of injury)

    And that's that. Serena Williams manages to get to her feet but can't continue. She's still in tears as she waves to the fans.

    She needs help from a medic as she limps off down the tunnel. Hopefully this is not the last we see of Serena Williams at Wimbledon.

    It will be a horrible, horrible ending if it is.

  15. Serena Williams somehow produces a serve that wins her the first point of that game, but there's absolutely no movement.

    A shot from Sasnovich, it's straight at Williams, but the American screams out in pain and collapses on the floor.

  16. game, set and match

    Game, set and match - Medvedev

    Struff 4-6 1-6 6-4 6-7 (3-7) Medvedev

    Jan-Lennard Struff serves out to take this set to a tie-break, but he then finds Daniil Medvedev in sensational form and the Russian storms to 6-3 to bring up three match points.

    He even finds time to stick his tongue out at the camera... and he wins it at the first attempt with a wonderful lob!

    Classy stuff from Medvedev, and the second seed is safely into round two.

  17. Tears flowing

    Annabel Croft
    Former British number one on BBC Radio 5 Live Sports Extra

    Just can't believe this has happened so early on. I don't she can either.

    Serena quite emotional. Clock is ticking down.

    This is really painful to watch.

  18. Sasnovich 3-3 S Williams*

    This is horrible to see. Serena Williams is in tears as she prepares to serve.

  19. Sasnovich 3-3 S Williams

    This one might not be going on for a while. Serena Williams is hitting it as hard as she can when it's close to her, but is unable to run at all when it's away from her.

    Sasnovich belts down an ace, but Williams, face covered in anguish, barely moves.

  20. Jonathan Jurejko
    BBC Sport at Wimbledon

    What rotten luck for Williams, and coming hot on the back of Mannarino's injury, there is an air of disbelief on Centre.

    Unless Serena's physical state improves quickly, it feels like there could be another retirement on the cards.
