Canada clock up 11 phases as they move to within two metres of the try line.

But Wales are awarded a penalty after Julianne Zussman appears to have stamped on Meg York, the Welsh replacement.

The TMO is going to have a look to see if a card is needed.

Tom Tierney makes five half-time substitutions and within six minutes, Ali Miller's try gives Ireland a lifeline.

Having wrestled back the momentum, Ciara Griffin wins a vital turnover. They need to build on this.

The referee has to have a talk with Carys Phillips, as he's not happy with the repeated infringements at the breakdown.

Phillips is told to report back to her Welsh players.

Canada are awarded a penalty and they successfully kick to touch for a line-out in Wales territory.

Canada earn a penalty and opt for a quick tap-and-go.

As they feed down the line to the left, there's a knock-on and the opportunity is wasted.

Ireland's woes are compounded as centre Katie Fitzhenry is yellow-carded.

Referee Ian Tempest issues the card for repeated high tackles by the Irish.

We're back under way at the UCD, by the way.

Ireland have a big second half on their hands.

Yep, there's a knock-on from Latoya Blackwood in the five jersey.

Scrum to Wales. They've survived again (for now).

Canada are camped on the Welsh line. Surely they've got to go over?

It looks like Alex Tessier has done it. But the referee wants to check for a knock-on.

Wales are hanging on here. Canada have been camped in the Welsh 22 for quite a while, and the only thing stopping them from adding to their lead is Wales' bloody-minded defending.

Here come Canada on the attack after turning over possession.

Karen Paquin feeds to Magali Harvey on the right wing but as she tries to dance over, two Welsh players come over and absolutely nail her. She's stopped in her tracks.

Canada continue to pick and go but somehow they're held up by a resolute Wales defence.

Stunned silence around the UCD Bowl at half-time.

A 14-0 lead is not flattering the visitors one little bit.

Ireland are too predictable and with a World Cup semi-final disappearing over the horizon, they'll have to find a creative spark from somewhere, and fast.

Well no-one in Ireland expected this.

Japan's first-half superiority has been almost total, with the visitors on top in every respect. Ireland are being completely out-played.

Having come from behind to overcome Australia in their first Group C game, another inspired comeback is required.

Ireland coach Tom Tierney must give the team talk of his life in the Irish dressing room at the interval.

Wales have a penalty and Elinor Snowsill opts to kick to touch... but it doesn't make touch. It dribbles over the dead ball line so it's brought back for a Canadian scrum.

That's a poor mistake from the Welsh.

Latoya Blackwood absolutely pummels Welsh lock Mel Clay to the ground. What a hit!

Canada hog possession but they can't get out of their own half at the moment.

The TMO decides that it's no try and a Wales penalty as a Canada player is caught off their feet.

Canada pounce immediately. Elinor Snowsill feeds to Magali Harvey, who has so much space on the right wing.

She's five metres out when the Welsh defence scramble.

The Canadians continue their onslaught and they think they've gone over underneath the posts...

There were a lot of mistakes by both teams but I think Wales will be happier.

Canada are seven points up but Wales' line speed is better and they're getting their hands on the ball a lot more than they did in the New Zealand game.

Their errors can be fixed. Wales look stronger, even though they're behind.
