England stalwart Rocky Clark goes down after putting in a huge hit. After treatment, the prop - winning her 96th cap today - rejoins her team at the scrum, with Wales so dominant in this opening 40, England to keep their experience on the field.

"It's been the story of the first half for Wales - they're not keeping possession for long enough. They had some great phases but a knock-on brought it to an end. They have shown they can penetrate the England defence, though."

England are being stretched to the limits here. Flanker Sioned Harries breaks a line, then Amy Day makes a burst towards the tryline, but another knock-on ends the move and we remain scoreless.

All Wales at the moment, camped in the England half. But still nothing to penetrate the England defence or really threaten the try line. How long can the teams keep this pace up? Surely the spaces will open as the teams tire after half-time.

There are some big hits going in out there. Laybourn slams Wales centre Adriana Taviner into touch to win a line-out on the Welsh 22.

Break in play in Swansea as Wales tight head prop Catrin Edwards has a new set of contact lenses put in by the physio.

Has a rugby match ever finished nil-nil? We could be breaking new ground here. A forward pass from England fly-half Ceri Large brings another attack to a premature end.

"Great defence by Wales on their own line, driving the England forwards backwards - and that's given them the chance to clear."

England on the break. Winger Ruth Laybourn turns on the afterburners. She's tackled five metres out, but still England press...

Try time? No. Another error in the forwards and Wales can clear.

"Wales have had a good bit of possession in the last 10 minutes or so. They're holding their own very well at the moment. If Wales can keep possession, they'll gain plenty of confidence."

It is all Wales at the moment. Great pace from Rowland and offload to Harries, who bursts into the 22. The forwards lose the ball in contact and England clear, then a Welsh handling error means the initiative is surrendered.

"Laurie Harries had plenty of distance, and it just went wide of the post. It was a cleaner strike than England managed, so at least we know now that Wales have got a kicker."

Penalty to Wales. Laurie Harries gives it a good punt. It has the distance ... but slides narrowly wide of the posts. After 20 minutes we're still waiting for a breakthrough in Swansea.

"Great to see such a big crowd at St Helen's. The game's gone from strength to strength with the exposure it's getting. More and more girls and women are taking up the game."

Rowe is not going to be able to continue here. She's taken off with a shoulder injury and replaced by Jenny Hawkins.

The crowd is about 60-40 in favour of the Welsh. It's not quite the Millennium Stadium 'cathedral' effect, but they are still pretty noisy.

It's Wales's turn to take the game to England now, working the ball through the phases. They have the put-in at the scrum inside England's half but we're just waiting for Wales lock Rebecca Rowe to receive some treatment.

Megan Goddard takes the kick for England, but it falls just short of the posts...

England dominate the opening passages of play. Already England debutant Sydney Gregson has shown her promise with a 20-metre run down the right wing. Wales coach Rhys Edwards is five seats down from me whispering into his headset....

England are enjoying the majority of possession but the Welsh defence is so far holding strong. Here's a chance though. England penalty, 30 yards out.
