It's exactly what you want from a derby, there have been so many swings of momentum in this game.

We're up to 18 phases but Dragons are still hovering around the half-way line.

The referee gets in the way and Dragons are given the put in at the scrum.

What entertainment. Everyone is on their feet.

The clock is in the red and Dragons are throwing the kitchen sink at Cardiff.

The home faithful are doing their best to get behind their team.

That's massive for the Dragons, especially with Cardiff going down to 14.

You think if they get one chance in Cardiff's 22 with the driving maul something could happen.

Cardiff just need to try and strangle the game as much as possible if they want to leave here with four points.

Rhodri Jones hoofs the ball upfield and Cardiff try to play the ball out under pressure.

Tinus de Beer takes a quick penalty and is over the line, but was it held up?

Time to bring in the TMO.

The Dragons have just lost that physicality battle a little bit, they're line speed has just slowed down a touch. They're still giving it a go though.

Dragons have the ball back, but they're going to have to run it from deep within their half.

Time is running out.

Cardiff looking more confident now, Mason Grady and Callum Sheedy have both made promising breaks.

A fourth try will surely be curtains for Dragons now.

Cardiff would have wanted the try after all that work, but the three points makes it a two score game. Dragons now have to chase the game.

Yes they will.

Callum Sheedy takes a look at the clock and calls for the tee.

He kicks his side two scores ahead with less than 10 minutes remaining.

Eighteen phases of attack and Cardiff still can't find the killer try.

James Botham is held up over the line by a heroic Dragons defence, but Cardiff come back for the advantage.

Will they think about posts here?

A costly mistake by Dragons.

Angus O'Brien takes the ball back into his own 22 and kicks it out on the full.

Can Cardiff capitalise?

Good work from Dan Thomas.

He makes up for his earlier fumble by ripping the ball off a charging Aaron Wainwright and Cardiff have three more minutes to make the most of a man advantage.

The Dragons driving maul is such a weapon for them, they've used it so well in the past few weeks.

Fourteen-man Dragons are on the attack, can they repeat Scarlets' smash and grab from last weekend?

Cardiff looked almost certain to score their bonus-point try, with Josh Adams within inches of the line.

There were options all over the pitch, maybe too many?

Somehow they find themselves in a foot race with Rio Dyer and Che Hope up the other end of the field.

How pivotal could that be?

A nasty looking injury to the aforementioned Dragons prop Rob Hunt.

The stretcher and gas and air are out, let's hope it's not as bad as it looks.

A warm applause from the Arms Park faithful as he leaves the field.

Taulupe's Faletau's work is done.

A solid 60 minutes from the Wales number eight on his second game back.

Not a bad replacement in Alun Lawrence.

Meanwhile Dragons have brought on Wyn Jones to steady the front row.
