Props Sebastian and Martinez have a little go at each other after a scrum collapses.

Scotland v Argentina in Newport!

And they both get a ticking off from an Italian referee.

You have to give credit Alun Lawrence for that try.

He kept the ball in, won it back and gave Cardiff the chance to attack the Dragons defence.

I asked earlier whether you thought Dragons could mount a comeback.

Thumbs up for yes, down for no.

Pretty clear answer from you lot.

I wonder if that's going to be the final score? Not at this rate!

The defence is winning the second half for both teams so far.

Both teams are strong defensively and there isn't much in the attacking game. It means the tempo has gone from this second half so far.

Dragons prop Martinez and Cardiff scrum-half Mulder are on.

And that's your lot from Faletau on his first appearance of the season.

To be fair, he marked it with a try. Will he also celebrate it with a win?

A huge kick from the left boot of Tom Bowen sends Cardiff some 50 metres up field.

Is there anything this kid can't do?

Beddall stealing the ball for a second time. That's exactly what you want from the young man.

He's strong on the ball, quick in and sees his chance. Great work.

Top work Harry Bedall.

The Dragons flanker clamps on to the ball after Woodman's tackle and wins the penalty.

Classic openside play from the Wales Under-20s captain.

With that pause, both teams start looking at their bench.

Cardiff props Sebastian and Southworth are on.

Dragons introduce flanker Woodman and lock Screech.

This second half has been a mess so far, a lot of mistakes, players losing the ball and poor kicking.

We've had a spell of about four minutes with the ball in play but to little consequence.

Wayward kicking.

Tom Bowen gives a glimpse of why people are getting excited about him.

The teenager gathered a long kick deep inside his own half but steps past the first tackler and glides past a second before he is snagged.

You get the feeling he could produce something at any moment.

The timing [of what Lyn Jones said] was disrespectful.

Everyone, players, ex-players, coaches, supporters more than anyone have their opinion on what’s going to happen to rugby in Wales during the next month and next few years, and he has his opinion.

Tonight’s about celebrating Welsh rugby. We’ve got a good crowd and it (the derby) is something very special so it’s not the day for discussing that kind of thing.

OK... who thinks Dragons can pull off a comeback?

It's three tries to one but only 10 points in it.

Thumbs up for a Dragons recovery, thumbs down for a Cardiff win.

Second half is under way

Wales head coach Steve Tandy is here in the Rodney Parade crowd as he runs the rule over potential selections for his first squad announcement next week.

Could outsiders such as Dragons flanker Shane Lewis-Hughes or Cardiff wing Tom Bowen be among those called up?

It’s disappointing isn’t it. Somebody with Lyn's experience knows the importance of derbies. He knows how important it is for regional players and coaches to focus just on the game.

There’s enough going on off the pitch in Welsh rugby at the moment, Lyn didn’t have to say that before this game.

We need some excitement in Wales at the moment. The crowd is out in force, they’re loud and I like what I see.

I'd love to see Dragons win and keep Lyn Jones quiet.

When Cardiff have reached the 22 they've looked really tidy and clinical. However we've seen the Dragons lose the ball a few times in that area.
