All over. JJ McDonagh has retired on his stool before round four. Boos ring out.

Chris Eubank Jr moves to 27 wins from 29 bouts.

George Groves and Callum Smith are getting their hands taped in their changing room as we inch close to this final. More on that next...

Oh, Mark Morrison 'Return of the Mack' is playing in the arena too. Beautiful stuff.

A left hook again from Chris Eubank Jr, followed by a right hook. That's probably the best combination of the three rounds. These two briefly break into a scrap, again the left hook lands on McDonagh, Eubank can't miss with it.

The crowd here are getting sucked in a little. Some whoops and hollers as the action heats up. It's still broadly quiet though in this chief support bout.

Tremendous work from Eubank to finish the round. A straight right allowed him to walk in closer, hooks followed from close range. McDonagh takes it, standing still but solid as the pain rolls in...

JJ McDonagh is glistening. I think it's sweat, maybe it's some kind of oil all over his body. He looks like he's ready for the beach to be honest.

But this ain't no holiday, he's in a battle. His hands are low but he's respectful of Chris Eubank Jr and not jumping forward with too much energy. Eubank Jr looks poised, patient, waiting for his man to step in. He tags him with a left hook again late in the round. Solid start from the Briton.

Former GB amateur and now undefeated pro Anthony Fowler is on board with his fellow Liverpudlian...

A fairly equal opening round until JJ McDonagh crashes down. It's a weird knockdown as the Irishman's legs disappear from under him. It was a left hook from Chris Eubank Jr, a flash left hook at that.

It catches the temple and after pausing to think about it, McDonagh just collapses. He's up and fights on but that was very much a case of a punch he did not see coming.

Here we go then, Chris Eubank Jr in flashy green shorts, white gloves. This could go 10 rounds, though it may not.

JJ McDonagh starts well with a couple of jabs, Eubank looks at his rival with focus, trying to work him out.

The atmosphere is a little quiet. We will monitor that for you as big-time boxing makes its Saudi Arabia debut.

Chris Eubank Jr is a mooted opponent for James DeGale later this year. This, on paper, is a bout to gather some sharpness or can Ireland's McDonagh spring a surprise?

Those of you who know your Prizefighter tournaments might recognize JJ McDonagh.

He is the 32-year-old former Irish super-middleweight champion who was a finalist in the Middleweights Prizefighter competition at the King's Hall in Belfast back in 2012.

McDonagh has a record of 16 wins and four losses with eight knockouts since turning professional in 2009 and won the WBA international title at light-heavyweight with a first round stoppage of Jake Ball in 2016.

His most recent activity was appearing in a three-round tournament in Dublin last March, where he won the first fight in the opening round and lost the following bout on points.

We've not seen a lot of Chris Eubank Jr. since he was beaten by George Groves on points last February in the World Boxing Super Series semi-finals.

But since then, the 29-year-old has been in Las Vegas training with Floyd Mayweather Senior, although he is still under the tutelage of Ronnie Davies.

He also says he would like to plan a big open-air fight at Brighton's Amex Stadium with either the winner of tonight's final or former world champion James DeGale.

"It's a stadium that I'd love to fight at," he told the Daily Mail.

"Yes, I want the rematch with George. Yes, I want the rematch with Saunders. Yes, I want to fight James DeGale. Yes, I want to fight Callum Smith."

So let's get the show rolling then. We've got some undercard action to accompany the build-up for the main event. Chris Eubank Jr is about to walk to the ring for a contest with JJ McDonagh.

All the way to Saudi Arabia for an undercard dust-up. Here comes Eubank, designer stubble, black gown. His first outing since losing to a certain George Groves in February...

Tonight's bout of course brings to an end season one of the World Boxing Super Series.

Oleksandr Usyk won the cruiserweight tournament, while either George Groves or Callum Smith will reign at super-middleweight.

But I want to know, have you enjoyed the Super Series? What have you liked about it? What hasn't worked? Just send me your thoughts on #bbcboxing.

That's right one and all, the World Boxing Super Series final is upon us. We aren't in Madison Square Garden, we aren't in the MGM Grand, we aren't at the O2 Arena, we are at King Abdullah Sports City, Jeddah.

There are many reasons why and we'll bring you them in a while. For now though, settle in and get ready for a mouthwatering dust up.

The height, reach and undefeated nature of Callum Smith versus the stunning jab, experience and ring craft of George Groves.

Let's do this in the desert.

Evander Holyfield is up for this. Prince Naseem Hamed is up for this. Are you?

Let's all go put our boxing shorts on, glove up and lap up the World Boxing Super Series final.

I'm leaving my computer now and about to conduct my own ring walk back to my chair.

The tune bringing me in? 'Gonna fly now', from Rocky.

Go do the same...

To use the words George Groves uttered this week. It's time to get "rowdy in Saudi".
