Round two goes a lot like round one, with the two boxers continuing to work each other out. Not many punches land. Dubois is on the front foot more, but it's Harper who connects the only proper punch, with a right hook late on.

This is a 10-round fight, neither fighter needs to win it in the first two.

I think Caroline Dubois has seen Terri Harper and suddenly realised how big Terri Harper is!

You knew this one was going to be tense. For the first minute of the opener these two dance round each other without landing a glove.

Dubois then leaps forward with a left jab but Harper sees it coming and smartly shuffles back to dodge. A slow burner. A first round for the purists.

The two fighters come together in the middle. They touch gloves, and then it's lights out away we go.

I think Harper is a good boxer. You know she's going to work hard, will do her best and always puts on fights that everyone wants to see.

She's challenged herself against some top names so you have to respect her for that. But I don't know if she has the pedigree to beat Dubois, who has an extensive amateur career and is a very technically sound boxer.

So if I had to put my money on it, I'd put it on a Dubois win but either way, it's going to be a great fight and I'm looking forward to it.

Time for the ringwalks. Terri Harper is out first.

Two years ago, it felt like everything might be over for Terri Harper.

She was emphatically beaten and stopped by Sandy Ryan up at welterweight and afterwards admitted retirement was a real possibility.

But Harper has since moved back down to what she says is her natural weight - and she looked in phenomenal shape at the weigh-in.

Harper insists she has left no stone unturned for this one. Whether those tough battles at the top level have taken something out of her remains to be see, but Harper seems to be absolutely up for it tonight.

I think Dubois wins on points. Mentally, physically and emotionally she's got the edge. But I don't think it will be as easy as she is saying.

We're told Jake Paul won't be ringside tonight, but his business partner Nakisa Bidarian is.

The MVP supremos have been constant pillars of opportunities for women's boxing in recent years and this event represents another big moment for MVP and their female stars.

It is their first event in the UK.

On the surface there’s plenty of bad blood between Caroline Dubois and Terri Harper. There have been mind games throughout the build-up

Dubois has openly questioned Harper's achievements and has largely been the instigator in the war of words over the past few months. At times, Harper looked thoroughly fed up with Dubois trying to bump shoulders during the various photo calls - rolling her eyes and shrugging as if to say "here we go again".

But things took a turn earlier this week. It was Harper who shoved Dubois during a media face-off, before laughing about it afterwards.

There was a brief moment of respect at the news conference when Harper said Dubois might be the best opponent she has faced. Dubois returned the compliment and acknowledged Harper’s achievements.

That truce didn't last long though. Moments later Harper said she doesn't want Dubois' respect anyway.

When all is said and done, though, don't be surprised if there's an embrace after the final bell.

I'm so excited to see Caroline take on her biggest challenge yet and experience a three-division world champion in Terri. But I look forward to seeing Caroline back up all the confidence and show how great she really is. I got Caroline winning. I can't be too hard on her, I see what she's doing. It's not often I get to watch greatness and I believe Dubois is greatness.

The path to undisputed is there for the winner tonight.

Stephanie Han currently holds the WBA title, while Turkish puncher Elif Nur Turhan is the IBF champion.

But Caroline Dubois has spent a long time chasing big names. She has called out the likes of Katie Taylor and Alycia Baumgardner looking for a marquee fight.

An undisputed crown is brilliant on paper - but in women’s boxing it doesn’t always guarantee mainstream recognition.

Just look at Chantelle Cameron. Cameron became the undisputed light-welterweight champion but only really broke into the wider public consciousness when she fought Irish superstar Katie Taylor. Without a rival of that magnitude since, Cameron’s profile has cooled a little.

Here we go. The main event is next....
