Reuben Morgan-Williams only now gets back on the field. He's been itching to get back involved on the touchline.

That try was too easy for the Ospreys. You can see the bemusement in the Dragons defence, Harrison Keddie and Lloyd Evans looking at each other and it's a simple linebreak.

Ospreys penalised at a ruck and Evans narrows the gap from 40 metres.

It could have been more but scrum-half Dane Blacker just fumbled a return pass with space opening up.

Luke Morgan did brilliantly there, at the back of the line coming narrow and going straight through the gap.

Keiran Williams in support gets the try fairly easily.

Cagey so far but Ospreys number eight Morgan Morris has already shown his worth with a couple of forays over the gain line.

Morris is only one of only two uncapped forwards in the Ospreys starting side, alongside prop Tom Botha.

How long he continues to be uncapped remains to be seen.

Wales head coach Warren Gatland has not picked Morris, despite him being one of the in-form players in Welsh rugby during the last few seasons.

No surprises, Reuben Morgan-Williams is back on here. He's got a big smile on his face, I think he knows he's left his gumshield in his sock.

Ospreys get another penalty which again they kick to touch.

Adam Beard gathers but the drive is halted before it gets going and Dragons get the penalty.

Big win for the home side and the local crowd know it. They're very happy with that.

Dragons hold out but the back line is offside.

Interestingly Ospreys turn down an easy kick at goal and Dan Edwards knocks it to the corner.

When you have such a good driving lineout as Ospreys, you would always back yourself.

Jack Walsh steps in at fly-half for Ospreys and puts in a really tricky kick that has Angus O'Brien scrambling close to his own try line.

They finally clear but Ospreys have a lineout on the 22. They'll fancy this.

That's a really great spot Richie! No wonder he didn't want to come off!

I think Reuben Morgan-Williams' gumshield was in his sock!

He's obviously kicked the ball, which triggered the sensor in the gumshield and the doctor wants him to come off for a HIA!

Reuben Morgan-Williams has been told he needs to come off following a head knock.

He looks fine and doesn't want to come off but Luke Davies is on.

Angus O'Brien is looking really good early on at full-back.

He's taken three high balls with real confidence.

This could be his position with Lloyd Evans' arrival at 10.

Dan Edwards did three years on the under-20s circuit but he's still only young.

The combination of him at 10 and Jack Walsh at full-back is good for Ospreys. I'm a big fan of Walsh and Edwards definitely has the potential to be a Wales international in the future.

Lloyd Evans is tackled but Dragons captain Ben Carter is penalised for going off his feet at the breakdown.

Needless penalty and Dan Edwards levels the scores from 35 metres out.

Rio Dyer gets his first touch of the ball. Beats the first man - as he always seems to do - but is swarmed by three white jerseys.

Leon Brown is a guy who hasn't been able to stay consistently fit.

Here's hoping after a summer of rehabbing himself back he can have a good game today as Dragons are going to need him.

Ospreys head coach Toby Booth spoke this week about how important discipline is in a Welsh derby.

In the Ospreys-Dragons he's been involved in, there have been 13 cards - included three red!

The game is 30 seconds old and already the first penalty!

Ospreys offside from a kick and Evans opens his account for his new club.

Nice start for the Dragons and for the new fly-half.
