Claressa Shields starts with a 'let's have a look' round as she gets the measure of the undefeated Ema Kozin.

A couple of clean shots landed, but a cautious opening round.

Here we go.... It's GWOAT time. 10x2 minute rounds.

Here comes the GWOAT....

Ema Kozin is coming out to a song I do not recognise and the crowd are not going to be singing along with this one!

It's GWOAT time.

Here comes Ema Kozin.

Welsh people loving a sing song is not a stereotype, it is a fact!

The Motorpoint Arena is currently very into Sweet Dreams (Are made of this) by the Eurythmics. it's like 6,000 people are doing bad karaoke up in here.

Sweet Child of Mine by Guns N Roses probably isn't going to dampen that vibe.

What's the name for a group of air guitarists?

Two Olympic gold medals, a three-weight world champion and the first boxer - male or female - to be undisputed champion in two divisions in the four-belt era - Claressa Shields is already one of the most decorated fighters in boxing history.

But the 26-year-old American does not take too kindly to the words 'self-proclaimed' being prefixed to her 'Greatest Woman of All Time' alias.

"When people say 'self-proclaimed' that's narcissistic, which I'm not," she tells BBC Sport.

"My accomplishments, performances, skills and history-making - that's why I'm the GWOAT. Fact."

Shields will fight in the United Kingdom for the first time as a professional when she defends her WBA, WBC, IBF and Ring magazine middleweight titles against Slovenia's Ema Kozin tonight.

Next on the schedule, the GWOAT, Claressa Shields.

Caroline Dubois is trying to do her post fight interview but is being drowned out by the crowd singing Sweet Caroline.

The song that will not go away! :)

Not much doubt about that decision.

That's a debut win in the books for Caroline Dubois!

Caroline Dubois is easing to a points win in her first professional fight.

She's looked impressive.

Essentially this is just attack versus defence.

Vaida Masiokaite is an experienced campaigner and she is doing everything she can to stay clear as Caroline Dubois looks to land with right, left combinations.

She is dominating the ring and landed a couple of big shots at the end of the round.

We are already at the halfway point of this one.

Caroline Dubois looks like she is just easing through the gears.

She is the aggressor but is looking to load up for a huge shot.

She has won the first two rounds.

Nice start from Caroline Dubois, she's keeping Vaida Masiokaite at length and has landed with some jabs. A confident first round in the paid ranks.

This is a six round contest.

I don't want to point any fingers, but Sweet Caroline? Come on Caroline.

As if that's a song we don't hear enough at the boxing!
