Blair Murray and Macs Page combine down the right as Scarlets threaten again.

This is already one-way traffic.

Scarlets have been quite sloppy in the first 10 minutes, but you have to applaud the Dragons defence, they’ve not let them through.

And another chance is missed by Scarlets as Gareth Davies knocks on as he tries to pick up the ball at the feet of one of his forwards.

Rhodri Jones replaces Taine Basham as Dragons need a front row for this next scrum.

This has been a terrible start for the hosts. Four penalties, a yellow card and have survived two potential tries by the skin of their teeth!

Unnecessary mistake from Kelleher-Griffiths, he didn’t need to do that at all.

Scarlets blow a third driving lineout in the same corner.

There was actually some good work by Dragons captain Ben Carter.

The Dragons prop was caught scooping the ball back on the ground at a ruck and is shown a yellow card.

This is a dreadful start by Dragons. Discipline!!

No you don't Ifan, and you also don't want to slip over behind your own try line when trying a sidestep as just happened to Dragons scrum-half Rhodri Williams.

Scarlets have a scrum five metres out after Dragons were caught trying to be too clever.

Scarlets have a really strong maul.

Dragons need to be careful, five minutes in and they’ve already given away three penalties, you don’t want to give Scarlets any easy opportunities.

Lousi's foot was in front of the ball when he picked it up so the score is wiped out.

Scarlets had two goes at the driving lineout but it looked a bit of a mess.

Sam Lousi thinks he has dived over after the initial push fell short.

Blair Murray has been great recently.

The whole back three the Scarlets have are really dangerous when they have the ball.

Just a reminder, Scarlets ended a three-game losing run with victory against Ospreys last month - and with four games remaining are still targeting both the URC play-offs.

Connacht's bonus point at Stormers means they have slipped to 12th and are six points off the play-off places.

Their other remaining games look pretty daunting - they host Leinster before flying to South Africa to face Lions and Sharks.

The second half of Judgement Day is under way.

Dragons head coach Filo Tiatia: "Scarlets are a good side and I enjoyed watching both derby games (with Ospreys) back-to-back.

"We've had a good look at Scarlets, and we've had a reminder of New Year's Day and some of the areas we weren't great at, so we are better.

"They are a transitional team, they feed on scraps with good athletes right across the park.

"They have several overseas players and international experience in that team, so they are a strong side."

Scarlets head coach Dwayne Peel: "It's undoubtedly an important game in terms of our league ambitions. The Dragons will be ultra-competitive. They have some top operators and they will want to get amongst us.

"The fact that both games are important for league positions adds a bit of added spice to the Judgement Day occasion.

"For our younger players who haven't played at the stadium before, it will be a special day for them and a great experience."

Dragons welcome back official co-captains Ben Carter and Angus O'Brien from long-term injuries but centre Aneurin Owen will lead the side on this occasion.

Wales centre Scott Williams will be making his first Dragons start against his former side. Williams is on permit from Pontypool.

Carter returns to action for the first time in almost six months after recovering from knee and ankle injuries.

The lock sustained a problem in his left knee while training with Wales at the end of October that required surgery.

The return of the 24-year-old was then delayed by a long-standing ankle issue which also needed an operation.

Fly-half O'Brien has also been missing since suffering a fractured thumb in January. Owen has led the side in the duo's absence and will continue in that leadership role.

O'Brien lines up as one of four backline changes, with wing Jared Rosser replacing the injured Rio Dyer and Ewan Rosser coming in for unavailable full-back Huw Anderson

Flanker Taine Basham and prop Dylan Kelleher-Griffiths start, with Harri Keddie and Rodrigo Martinez ruled out by injury.

Dragons: Ewan Rosser; Ashton Hewitt, Aneurin Owen (capt), Scott Williams, Jared Rosser; Angus O'Brien, Rhodri Williams; Dylan Kelleher-Griffiths, Elliot Dee, Paula Latu, Ben Carter, Ryan Woodman, Shane Lewis-Hughes, Taine Basham, Aaron Wainwright.

Replacements: Brodie Coghlan, Rhodri Jones, Chris Coleman, Barny Langton-Cryer, Dan Lydiate, Dane Blacker, Will Reed, Joe Westwood.

Cardiff briefly move up to sixth place in the URC with Munster and Ulster about to start their games.

Ospreys remain in 13th place and any play-off hopes are now well and truly fading.

Perhaps the most alarming stat from that game was a combined total of 30 penalties.

No wonder we had five yellow cards. To be fair to referee Ben Connor, he could have brandished a few more!

Gabriel Hamer-Webb told Radio Wales: “This is what we want.

“A tonne of fans, a tonne of passion, especially after all the antics last week we wanted to prove to ourselves what we’re made of.

“We’re pushing for the top eight, we want to take the club to places it’s never been before.

“It’s been a great occasion and we can’t ask for much more.”
