That's all we've got time for here.

Make sure you join us tomorrow for radio and text commentary of the remaining quarter-finals.

In the meantime, have a read about the man of the moment, Kyle Edmund, who has reached a Grand Slam semi-final for the first time.

Caroline Wozniacki and Carla Suarez Navarro are now bidding to join Belgium's Elise Mertens in the semi-finals of the women's draw.

On Wednesday, former champion Angelique Kerber takes on Madison Keys and Simona Halep faces Karolina Pliskova in the remaining last-eight matches.

So Rafa Nadal's Australian Open campaign came to a painful end today.

It means world number six Marin Cilic will play Britain's Kyle Edmund in the semi-finals.

Battling it out for a place in the final four of the men's draw tomorrow is defending champion Roger Federer against Tomas Berdych, and world number 97 Tennys Sandgren faces South Korea's rising star Chung Hyeon.

Rafael Nadal will retain his #1 ranking, but if Roger Federer wins the #AusOpen he will only be 155 ranking points behind.

An odd sort of symmetry at work here.

Cilic on facing Kyle Edmund next: "He had an amazing run and a great match today. I have to keep going with my own game. Kyle is also a big hitter so I have to take things into my own hands and deal with my own court in the best way possible."

Of course, Marin Cilic knows how it feels to play with an injury, with the eyes of the tennis world watching intently.

He struggled big time in last year's Wimbledon final and was beaten in straight sets by a certain Mr Federer.

Cilic looks in fine fettle now and here's how he feels about booking a semi-final with Britain's Kyle Edmund.

More from Marin Cilic: "I was playing better towards the end of the match. I think I had a lot of chances in all the sets but Rafa came up with good shots and good serves in critical moments. That's the way he has always been.

"After the tie-break I thought I had to lift up my game. I wanted to serve a bit better and then I started to feel the ball really good. That intensity brought the level of the game up and it was really critical at the end."

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-2 Cilic

Marin Cilic, speaking on court: "It was an unbelievable performance from both of us and it's really unfortunate for Rafa. He always gives his best and it's unfortunate for him to end this way. I was really paying attention to these first couple of games [in the final set] and trying to keep my intensity up. It was important for me to continue with my own game and not look across the net."

There's frustration and fury on the face of Nadal because his body has let him down, but there's delight for Marin Cilic.

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-2 Cilic

And that result means we've got an absolute slog-fest in Thursday's semi-final.

It's going to be world number six Marin Cilic against British number two Kyle Edmund.

Nadal is a player of such integrity. He gives all of himself every second he's on the court. He's even struggling to get up the sets to get off the court. Cilic's body was able to hold up, and Rafa's wasn't.

Nadal retires

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-2 Cilic

The world number one can barely walk as he limps up the stairs and into the locker room.

Before exiting the Rod Laver Arena, Nadal threw down his racquet in sheer frustration. He's livid about the outcome.

Even though he's not done it the way he wanted, Cilic looks so strong out there and deserves his place in the semi-final.

Game, set and match - Nadal retires

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-2 Cilic

Break point number six is taken by Cilic.

And it's all over. Nadal goes to the chair umpire and has to retire. Such a sad ending.

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-1 Cilic*

A fifth break point against the Nadal serve.

The Spaniard grimaces as he throws down court, and Cilic nets. Another one saved.

The world number one brings up the advantage but spikes a forehand into the net.

Deuce for the fourth time.

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-1 Cilic*

Cilic is making Nadal come to the net and he simply can't do it. He's not fit enough.

The Croat brings up a fourth break opportunity but mucks it up again by plonking a forehand wide. He challenges, it's quite a way over in reality.

Back to deuce.

Nadal 6-3 3-6 7-6 (7-5) 2-6 0-1 Cilic*

A limping Nadal is facing three break points. He finishes one off with a seething forehand, which he doesn't have to scamper for.

Same again to make it 30-40.

And then Cilic carelessly shanks wide. Nadal's not done just yet!

Sam Smith

Former British number one on BBC Radio 5 live sports extra at Melbourne Park

Rafa is protecting and nursing his body. He's not moving in an extreme way, and he has to against Cilic. His footwork is not quite as precise and he's short on the points.

*Nadal 6-3 3-6 7-6 (7-5) 2-6 0-1 Cilic

Marin Cilic holds to love and world number one Rafael Nadal can barely walk, run, or return.

This is a sorry, sorry sight that no one wants to see. Nadal's obviously injured and in a lot of pain.

Croatian flags are flying inside the Rod Laver Arena. Rafa Nadal is going to have to do this the hard way.

Game and fourth set

Nadal 6-3 3-6 7-6 (7-5) 2-6 Cilic*

Fourth set in the bag.

Get the snacks in. We're going for the full-on five setter!

Set point

Nadal 6-3 3-6 7-6 (7-5) 2-5 Cilic*

I just made a 'pewwwwwwww' sound - like they do in the cartooons - to help describe a Cilic forehand winner. It had so much whip and whistle on it.

We go to deuce and Nadal forces the ball wide to hand Cilic a set point.

Sam Smith

Former British number one on BBC Radio 5 live sports extra at Melbourne Park

This is the time for Cilic to apply pressure and break, so he can start serving in the fifth.

It feels like Nadal is assessing how bad the injury is while he's playing the points.

*Nadal 6-3 3-6 7-6 (7-5) 2-5 Cilic

Nadal pulls out the hotdog! Damn, that's good. But it doesn't beat Cilic who's ready and waiting at the net.

A 15th backhand winner down the line from the world number six makes it 40-15 and although he mucks up at the net to give Rafa a faint hope, Cilic powers a huge forehand winner cross-court to hold.

Three break points saved

Nadal 6-3 3-6 7-6 (7-5) 2-4 Cilic*

Both players are back out on court, and Cilic remains unfazed by the gap in play. He moves 0-30 up before bringing up three break points.

The first goes amiss when Cilic lands a forehand wide, and then Nadal overpowers him with a big serve.

Cilic tries to chase down a Nadal volley and although he makes it, he's wrong-footed by the Spaniard again.

Three break points gone, and Nadal goes on to hold. That is a terrifying response from the man who just needed a medical time out.

Whilst Rafa gets a rub down, Cilic is doing some serious squats.

Bend and snap, Marin. Bend and snap.

Now then, we're going to have a quick break in play.

Rafael Nadal's called the trainer out to look at something. He's taking some tablets for what appears to be a hip/thigh problem.

The world number one is now lying on the court and having an intense bit of physio to try and solve the issue.

Cilic's backhand is delicious.

Marin Cilic isn't instinctive - he's dexterous. There's a little more shimmy about him these days.

*Nadal 6-3 3-6 7-6 (7-5) 1-4 Cilic

Ridiculous from Cilic. His crowd-pleasing shot sends his partner wild in the players' box!

The big man dips down low to pick up an unlikely winner and he holds for a 4-1 lead in the fourth.

Strap yourselves in, we could be going all the way.

Cilic breaks

Nadal 6-3 3-6 7-6 (7-5) 1-3 Cilic*

What. A. Rally.

After 23 shots, a tired-looking Cilic pokes a backhand into the partition.

He recovers to bring up a single break point.

HE'S GOT IT. Marin Cilic finds the line with a swinging forehand. He's a break up.

*Nadal 6-3 3-6 7-6 (7-5) 1-2 Cilic

Nadal's got his head in his hands here after Cilic pops over another volley.

The hold follows.

*Nadal 6-3 3-6 7-6 (7-5) 1-1 Cilic

Marin Cilic isn't getting tired or bored of the big serves. He throws down another banger for 40-15.

Unfortunately for the Croat, he hits over the baseline on the next point and then slaps the net for deuce. A bit of a waste.

A gorgeous volley gives the world number six the advantage but then he double faults again. Back to deuce.

This is the kind of tennis geekery I can get on board with.

Stats you need: Cilic bidding to be first palindromic #AusOpen champ since Seles 22 years ago.

Sam Smith

Former British number one on BBC Radio 5 live sports extra at Melbourne Park

Conditions out here favour Cilic. He's a flatter ball striker.

Nadal 6-3 3-6 7-6 (7-5) 1-1 Cilic*

Marin Cilic has forgotten about the disappointment of that tie-break, and has commandeered a 0-30 lead on Nadal's serve.

Oh, no. Wait. The Spaniard has taken it back to 30-30.

Nadal goes on to hold. Game face on.

Sam Smith

Former British number one on BBC Radio 5 live sports extra at Melbourne Park

I see no reason why Cilic can't take the next two sets. If he continues to serve well and return well - he's been returning brilliantly tonight.

*Nadal 6-3 3-6 7-6 (7-5) 0-1 Cilic

Cilic gets off to a very confident start in the fourth.

A hold to 15 sets the world number six on his way.

Game and third set - Nadal

Smash from Rafa Nadal, and there's a huge cheer and fist pump from the world number one!

Nadal's a set away from a place in the semi-finals.
