MELBOURNE, Australia -- The grimace on Novak Djokovic's face after slipping on the white 'MELBOURNE' lettering behind the baseline at Rod Laver Arena was enough to suggest the world No. 1's chances of defending his Australian Open title had just taken a serious hit.

The NBA star Nikola Jokic, who was pictured hugging Djokovic at one of the events, also tested positive. 'Prayers up to all the players that have contracted COVID-19,' another tennis star, Nick Kyrgios, said on Twitter after the tournament's cancellation. The latest tweets from @djokernole.

In the third round at Melbourne Park on Friday, Djokovic appeared to be cruising to a straight sets victory over American Taylor Fritz when he fell awkwardly and immediately signaled for the trainer. After undertaking an extended medical timeout, Djokovic returned to the court but appeared significantly hampered in his movement and experiencing serious pain.

The 17-time major champion continually felt around the right side of his abdomen, often attempting to stretch it out between points. He frequently winced as he tracked down balls, giving up on plenty which were struck only a few feet either side of his racket.

In the blink of an eye, Fritz leveled the match at two sets apiece and for the first time in the tournament, there should have been real concern in the Djokovic camp. But the Serbian took the decider 6-2, letting out a giant roar inside center court when he secured match point after three hours and 25 minutes.

'I know it's a tear of the muscle, definitely,' a deflated Djokovic said immediately after the match. 'I don't know if I'll manage to recover in less than two days. I'm not sure if I'll be able to play the next match.'

There has yet to be a proper diagnosis made public about Djokovic, 33, making his health the greatest mystery over the middle weekend of the Australian Open. The question remains: Would he be able to continue his pursuit of a record ninth crown Down Under, and if not, who would step up and lift the Norman Brookes Challenge Cup?

Much of the speculation following the win over Fritz was that the muscle Djokovic had injured was his right oblique, one of two diagonally-oriented abdominal muscles which run from the rib cage to the anterior trunk, or pelvis. An extreme amount of stress is placed on these muscles in sports which require high rotation, such as tennis. And few, if anyone, in the sport puts more stress and strain on their body than Djokovic.

It takes the average person between eight and 10 weeks to fully recover from a torn oblique, according to Harvard Medical School, but Djokovic had just 48 hours to get himself right for his fourth-round match against 2016 Wimbledon finalist Milos Raonic.

Djokovic was absent from the precinct on Day 6 but returned Sunday for a light gym session, which consisted of some stretching and jogging, before stepping onto John Cain Arena for a practice hit in the afternoon.

A few hours later, he was squeaking and sliding his way around Rod Laver Arena, once again mimicking the defensive qualities of a brick wall and leaving Raonic scratching his head in a combination of disbelief and frustration. Djokovic may have been wearing a large anti-inflammatory patch on the right side of his abdomen, but suddenly he looked more like the player we've become accustomed to seeing over the years. Had fans not known about his tumble in the previous match, they never would have guessed he was dealing with a potentially serious injury.

Djokovic needed a little less than three hours to dispatch Raonic 7-6(4), 4-6, 6-1, 6-4, record his 300th Grand Slam victory and move into the quarterfinals at the Australian Open for a record 12th time. How could he possibly manage such a feat with what he believes is a torn oblique?

'The term 'muscle tear' can often set off alarm bells, but they are generally scalable and graded from one to three,' ESPN injury analyst Stephania Bell said. 'Grade 1, which it could be, suggests little to no structural damage, and while painful, may not adversely affect function in a serious way. Sometimes an athlete can feel a pop or a pull and this is what makes them refer to it as a tear.

'A complete tear would likely prevent him from playing, given the pain and the functional compromise. Things which demand power, such as serving, and things that put the muscles on extreme stretch, such as stretching wide to reach a shot, perhaps even some cross-body shots, would be challenging for Djokovic if he had a full-blown oblique tear.'

After the win against Raonic, Djokovic confirmed he had undergone an MRI in Melbourne and now knows the extent of the injury, although he again didn't provide any specific details. As long as he is still standing in the tournament, he isn't eager to share his diagnosis with his rivals.

'I understand that you want to know, but I really don't want to get into what it is,' he told the press after beating Raonic. 'It's not ideal for me. I mean, I have definitely felt better. The combination of painkillers, treatment and some willpower [is getting me through], but I don't want to talk about it now. It's irrelevant.'

Just 48 hours later, Djokovic returned to Rod Laver Arena to beat sixth-seeded Alexander Zverev 6-7 (6), 6-2, 6-4, 7-6 (6), moving freely and hunting balls down from all parts of the court to secure a place in the semifinals.

'It was really anybody's game. A roller coaster of a match, in every sense of that word,' Djokovic said Tuesday. 'I didn't start well and it took me a while to feel better, in terms of movement, rotation and hitting. Towards the end of the first [set], I started to feel better on the court and then I also played better. Walking into this match today, I knew it would probably be the toughest match of the tournament.'

Djokovic's ability to recover in such a short period of time and then overcome both Raonic and Zverev is something which has drawn the attention of many around the tour, including Serena Williams' longtime coach, Patrick Mouratoglou.

'Sometimes Novak plays with the mind of an opponent when he's in trouble,' Mouratoglou told Tennis Majors. 'He pretends he's giving up, and then, boom. He plays again. He's done that a lot of times in the past.'

Former Australian doubles icon Todd Woodbridge also weighed in, saying, 'He's going to be fine. I'd say to the rest of the field, watch out, because we've seen him do these types of things before, have a bit of a hiccup and still win majors.'

It's not the first time Djokovic has had to fight through an injury at a Grand Slam. At Wimbledon in 2017, he battled a nagging elbow ailment, yet still reached the quarterfinals.

At the 2019 US Open, he withdrew in the fourth round after a left shoulder injury got the better of him, while at last year's tournament in New York, he fought through neck stiffness to reach the fourth round. He dropped just one set in his first three matches before being defaulted for striking a linesperson in the throat in his round of 16 tie against Spain's Pablo Carreno Busta.

Djokovic will now face qualifier Aslan Karatsev, who in his first Grand Slam main draw appearance has enjoyed a dream run to the semifinals, with the winner to earn a place in Sunday's Australian Open final.

'I had not seen [Karatsev] play before the Australian Open [but] I have seen him play during the tournament here,' he said Tuesday. He has impressed me a lot with his movement, his firepower from the baseline. It's going to be our first encounter and he has nothing to lose.'

After Day 7, Djokovic said, 'If it was any other tournament, I would retire. I definitely wouldn't be playing. But it's a Grand Slam. It matters a lot to me at this stage of my career. I have to accept the circumstances and the condition I'm in at the moment and that I'll probably feel pain all of the way through.

If Djokovic has indeed torn his oblique, regardless of the grade of the injury, it's going to be a case of management, as opposed to having it fully healed before the end of the tournament.

'Most of his time between suffering the original injury and his next round will be spent in recovery, getting treatment,' Bell said. 'Given the demands of a Grand Slam tournament, balancing recovery while maintaining conditioning and readiness to play will be the challenge.'

Djokovic's record on the blue courts of Melbourne Park is 77-5, and post-fourth-round is an even more impressive 25-3. Even at 75% healthy, Djokovic would likely still be favored to beat just about everyone left in his path to Slam No. 18.

The 28th-ranked Karatsev saved 23 of 28 break points to advance to his second final of the year following a 7-5 4-6 6-4 victory, gaining a measure of revenge for his defeat by Djokovic in the last four of the Australian Open.

It was a second surprise loss in as many weeks for Djokovic, who was also beaten in the last 16 of the Monte Carlo Masters by Britain’s Dan Evans.

Djokovic is registered for the Madrid Open but did not confirm whether he would play at the May 2-9 Masters-level event, which will feature reigning French Open champion Rafael Nadal.

“Roland Garros is the main goal but I need to play better if I’m thinking about doing something there. I have a lot of work ahead of me,” said the 18-time Grand Slam champion.

Djokovic commended the “bravery” of Karatsev and his “excellent play in the important moments” but revealed he felt “dizzy” in the third set.

Karatsev rose from 114th to inside the top 50 following his improbable run as a qualifier at the Australian Open, as Djokovic won the tournament for a record ninth time.

“You have to put (in) like 200 per cent to beat this guy, it’s like playing against a wall,” said Karatsev.

“This is definitely (the biggest win of my career), it’s the world No. 1,” he added.

“I’m really happy, I put everything on the court. Battery 4 free download mac. The match was long. I’m really happy with my performance today.”

Djokovic’s loss comes after he said he hoped tennis players won’t be forced to have a COVID-19 vaccine to keep competing. The 33-year-old has previously spoken of his objection to mandatory jabs, and doubled down on his stance during the week.

“And I will keep the decision as to whether I’m going to get vaccinated or not to myself. It’s an intimate decision, and I don’t want to go into this game of pro and against vaccines, which the media is unfortunately creating these days.

“I don’t want to be labelled as someone who is against or who is for vaccines. I’m not going to answer the question … and hope that everyone will respect that.”

Djokovic, the 2009 and 2011 champion at the event which is played at a venue which carries his name, surrendered a 3-0 advantage in the opening set as he dropped serve three times.

The Serb then fell 4-2 behind in the second but summoned his well-documented powers of recovery to win four straight games and send the match to a deciding set.

Dubai champion Karatsev fended off eight break points in the third set before winning Djokovic’s service game to move 4-3 ahead and leave the top seed on the brink.

Djokovic saved a match point down 5-3 to force Karatsev to serve it out. The third seed saved two further break points as he completed a landmark win after three hours and 25 minutes.

Karatsev will face 10th-ranked Matteo Berrettini in the final after he overcame Japan’s world No. 126 Taro Daniel. Free building design software for mac.

The Italian dropped serve while serving for the match in the second set but regrouped to advance 6-1, 6-7 (5/7), 6-0.

Second seed Berrettini will target his first title since winning on grass at Stuttgart in June 2019.

Daniel had been the first lucky loser to reach an ATP semi-final this year.
