Another card looked to be coming, and the referee has brandished another yellow card to the Dragons - this time to Dane Blacker.

Things go from bad to worse for the visitors, who will now be a man down to start the second half as well.

This has not been a classic, and the Ospreys need a lot more if they are to secure a bonus-point win.

The clock goes red, are there any more points to come?

Eventually the dam broke.

We were saying Ospreys hadn't been clinical enough but they get the try, they get the conversion and they are back into the game.

Dragons will be looking to get to half-time with the scores as they are, because in the first half they have really been a match for this Ospreys side.

The Ospreys are to within a metre, and have a penalty coming for offside.

A bundle of bodies cross the try-line but the referee says the ball has been held up.

We will go back for the penalty.

The Dragons have been warned again about discipline. 14 could become 13 very soon at this rate.

I love the scrum as much as the next man, but from a supporter's point of view, this can be frustrating.

The set-piece continues to misfire from the Ospreys.

Matthew Screech gets to the line-out, but unfortunately for the Dragons forward the ball bounces forward, so we will have a scrum for the Ospreys.

The Dragons managed to waste a couple minutes there, but it is the Ospreys who eventually win a penalty at the scrum.

They are already inside the Dragons 22 and kick to the corner.

They will have the line-out from five metres out.

The scrum needs to be reset, and the referee is not happy with the behaviour of the two packs.

A quick talking to should sort things out!

Chris Hollins jumps into the Dragons scrum to replace Aaron Wainwright.

Ospreys have to make this opportunity count. They say on average seven to eight points on a yellow card - and the last player Dragons want to lose is Aaron Wainwright.

This time the cheers come from the Dragons players, as the pack force the Ospreys backwards at the driving maul and win the turnover.

The Dragons fell apart when going down a man last week, they will want to avoid a similar fate in the remaining minutes of this first half.

The penalty count had been creeping up by the Dragons, and the referee has now had enough.

Aaron Wainwright - who has been one of the Dragons' best players this season - is sent to the sin bin.

Ospreys kick to the corner again. A big 10 minutes now.

Ospreys wing Luke Morgan gets up to full speed for the first time in the game and makes good metres down the right wing.

Another chance for Ospreys to attack inside the Dragons' 22 now after opting to kick to the corner from another penalty.

Less than 10 minutes to go in the half.

Brilliant tackle from Keiran Williams on Aneurin Owen just inside his own half as the Dragons were looking to switch the ball to the right.

And Justin Tipuric was there to follow-up and win a penalty for the Ospreys.

That's the biggest cheer of the day from the home crowd.

It's all a bit predictable from Ospreys.

Let's be honest, they have been a bit safe in what they are doing.

For the Dragons, it's pretty easy to deal with. Ospreys have to start mixing it up.

Jack Walsh thinks he finds a gap in the Dragons defence but Aneurin Owen makes an excellent tackle to stop the Ospreys full-back in his tracks.

Another brief stoppage in play as a couple players receive medical treatment, nothing too serious though.

Ospreys continue to test the likes of Rio Dyer and Ewan Rosser under the high ball but so far the Dragons backs have been up to the challenge.

There has been plenty of huff and puff from Ospreys but they are not really challenging this Dragons defence.

Dragons are just meeting their physicality and coming out on top.
