For a woman who only lost one round according to a few scorecards, that was a hard for her.

Caroline Dubois' straight over to her corner. The celebrations start now.

She's done it! Caroline Dubois becomes the unified lightweight champion with two judges calling it 98-91 in her favour and the other calling her a 97-92 winner.

Yep, Caroline Dubois knocked Terri Harper down in the sixth. After that Dubois had confidence. She dominated from then on.

I think Dubois' knockdown will be the factor.

So it'll go to the judges. Both fighters celebrate.

More like it from Harper who connects a few head shots with a minute to go. That has the crowd on their feet. Harper hears them and whacks a few more right hands.

The round gets epic, Dubois is holding on and she makes it to the bell.

Great fight.

That was a round I never thought I'd see; Harper and Dubois going toe-to-toe like a couple of middleweights from the 1950s.

One final round. Who you got?

Harper has to go for it. She manages to land a few body blows but that opens her own defences up and Dubois manages to squeeze through a couple of high jabs.

This title fight has lit up, with loads of trades. An even round, but Dubois surely has the scorecard lead.

A very bad looking cut, but it seemed to tell Harper 'I'm going to set my feet, throw a shot at see how it goes' and she caught Dubois with a couple of good shots - but there is nothing wrong with her chin.

Harper's corner have a real job to do cleaning their boxer up. There's a lot of blood coming from a cut just above her left eye.

Cut the ring off a bit more and double or triple the jabs. She is posing too much - when she lands, it is devastating so I want her to be more active.

Into the business end. Round eight starts with a clash of heads and Harper's eyebrow gets cut. Her face bloodies quickly.

Dubois continues to control the momentum. She rattles off a combination. With 15 seconds to go in the round she puts Harper into the corner but she can't finish her opponent off.

We're all set up for a big finale now with Dubois surely ahead on the scorecards.

Dubois comes forward and Harper just about manages to block a jab.

Harper knows she has to come forward, she has to attack. But Dubois cuts off the angles and takes this latest round.

"We're not getting stopped by her. Dig deep." Harper's corner tell her ahead of round seven.

Finally we burst into life! Dubois gets the breakthrough and sits Harper down who survives the count.

It's a great one-two combo to the head with Harper on the ropes. It really does come out of nowhere. Dubois' so relieved she leaps up into the air to celebrate.

The referee starts giving out to her for not returning to her corner. Harper looks dazed but the bell rings.

This is still a really tight and really technical fight.

You can win a round in this fight with four punches. This is a chess match.

It stays tense for another round. Nervy. Neither boxer wants to give anything away.

Again Dubois is doing more of the attacking, but Harper is easily evading her shots.

Before the fight Dubois was very vocal about finishing this bout early. Harper said she'd win it in the later rounds.

I really can't call this. We're almost halfway through the fight and there's really not been a true highlight punch yet.

We should've seen this coming with so much on the line. And, of course, things can change so quickly. Dubois finishes the round strongly with a nice combo, but the bell stops her progress.
