How Thanasi Kokkinakis predicted the knee injury that ruined his Wimbledon campaign in a light-hearted social media post

Thanasi Kokkinakis will have an MRI scan in London to determine the extent of the injury that has wrecked his Wimbledon hopes - after he appeared to predict the heartbreaking turn of events in a social media post.

The joy of the Aussie's remarkable triumph over 17th seed Felix Auger-Aliassime from two sets down on Wednesday turned to misery less than 24 hours later in his second-round match against French qualifier Lucas Pouille.

Trailing 2-6 7-5 4-2, Kokkinakis - a big man who's often talked of how tentative he feels with his movement on grass courts - slipped and twisted his left knee while trying to retrieve a forehand.

The 28-year-old tumbled over, clearly in agony, while former French No.1 Pouille crossed the court to help attend to him.

Kokkinakis eventually soldiered on for one more game, but at 5-2 down limped across to tell Pouille there was no way he could continue.

The day before the clash, the Aussie re-tweeted a post showing a video of cooked meat falling off a bone accompanied by the caption 'Thanasi Kokkinakis' legs when he woke up this morning after playing 15 sets in 4 days', referring to his marathon five-set win over Felix Auger-Aliassime, which took two days.

Kokkinakis added the word 'Accurate' with a tears of joy emoji.

'It was a tricky match. It started well but there was a weird kind of energy out there, it felt strange,' Kokkinakis said after his tournament ended.

The Australian had been unhappy with a heckler in the crowd the previous day who had badgered him and Auger-Aliassime to play on after rain had made the surface treacherous.

A fortnight ago Kokkinakis suffered a similar tumble at the Queen's Club Championship on a wet court, which caused a medial collateral ligament injury that kept him out of action for a week.

He also had sprained his troublesome left knee two years ago at a pre-Wimbledon Challenger tournament in nearby Surbiton, which cost him a month out of the sport.

'He was starting to play some good tennis and I was trying to rally and just slipped and hurt my knee,' he said.

'I'm going to see the severity after some scans - but I know I've done a similar injury to what I did at Queen's Club.

'But it feels a bit worse, that's my gut feeling.'

Kokkinakis had planned to play a hard-court tournament in Atlanta next.

'But now I've got to have an MRI to see if that's going to be possible or not,' the world No.93 said.

He had some stern words for a spectator who blasted him and opponent Auger-Aliassime for leaving the court when it rained during their two-day clash.

'All right, have a go and try to move on a dewy grass court. It's one of the hardest things, especially with me injuring myself at Queen's and also a couple of years back.

'I'm not going to let some muppet in the crowd dictate when I go back on the court, whether it means waiting two extra minutes.

'I was walking on eggshells a little bit at the start, but it started to get comfortable.'
