That was a hard round. This fight is taking it's toll and that was only round six. It was a very hard round to score.

This is scheduled for 10 rounds so we go beyond the halfway point and Taylor is not showing any signs of slowing.

Neither is Cameron, to be fair, she looks to have taken more damage but is still light on her feet as she bounce back and away from her rival.

A lovely right hook from Cameron as she closes the distance, that might be her best shot of the night.

A much better round from the champion.

Chantelle is applying smart pressure. Katie is holding centre ground so well and that is what she needs to do.

"You've got to stay switched on. I don't care how you feel, it's how you look," Katie Taylor's trainer Ross Enamait says between rounds.

Cameron's corner have plenty of work to do between rounds as they try to deal with that huge gash on her forehead, it looks like they've done a pretty good job for now.

Every time Taylor attacks she does it with combinations.

It's champion Cameron who is having to do the chasing around the ring and she isn't always finding her range before Taylor gets busy.

This is an insane pace.

Cameron is fighting fire with fire. Incredible action. Taylor is fighting on back foot like six months ago, but this time she is prepared to plant her feet once Cameron comes in and fire off combinations.

The crowd are loving this, huge roars every time Taylor throws.

"Katie, Katie, Katie", they scream.

And she is throwing plenty in this round. They aren't all clean shots but she is staying busy and they judges will like that.

Cameron lands a lovely right hook but the round ends with the pair holding.

That was perfect boxing from Katie there. She needs to keep doing it and not get backed up by the bigger, stronger girl.

There's some suggestion that Taylor may have injured her knee or ankle when she hit the canvas in round one. I'll keep an eye on that but she seems to be moving OK.

It's Cameron who comes out with intent in round two.

A lovely jab forces Taylor back into the corner and Cameron keeps the pressure on.

Taylor circles out and has some success of her own.

It gets a little dirty in the clinch with Cameron landing round the back of the head and Taylor responds with a short hook.

They need to be separated at the bell. This is already very tasty.

That looked to me like Katie's legs dropped about six inches after that jab.

Taylor started slowly in May but she is out of the traps quickly here.

There's already swelling on Cameron's forehead after just a minute as Taylor finds a home early.

But then Taylor goes down but the referee has deemed it a slip. It looked like a knockdown to me.

Wow! what a start.

Master of ceremonies David Diamante is doing his thing, "this is it, the time has come!", he says.

Both fighters are wearing black and gold as Diamante runs us through their respective records. It's the first time we hear Katie Taylor announced with a loss on hers.

The noise is deafening as the 3Arena shows support for the home fighter.

Unsurprisingly, boos ring out as undisputed light-welterweight champion Chantelle Cameron is introduced.

Here we go!

Chantelle Cameron handed Katie Taylor her first professional loss back in May.

Can the Irishwoman do the same to the undefeated Cameron here?

And her comes the champion Chantelle Cameron with Strike's 'U Sure Do' switching into a Western number before eventually transitioning into a bit of drum and bass.

I'm not sure how often you'll get a mega mix like that.

She's quickly down to the ring as the crowd chants "ole, ole, ole, Taylor".
