Scotland rumble forward. Another penalty coming...
Wales are on a last warning.

What an offload by Huw Jones - that's as good as you'll see in Test rugby
Scotland 13-7 Wales
With a penalty advantage up their sleeve, Scotland go again but Duhan van der Merwe can't hold on to the ball.
Scotland kick to the corner - and the crowd love it.
Scotland 13-7 Wales
For the first time today, Duhan van der Merwe turns on the afterburners and is like a blur along the touchline, breaking through tackles.

George Turner is looking for a second try but he's just held up.
Jack Dempsey's foolishly grapples his man round the neck and that let's Wales off the hook. Really daft from the Scottish back-row replacement.

I was about to criticise Finn Russell for trying to kick and getting charged down... then he pulls out a kick like that!
Scotland 13-7 Wales
Scotland get motoring in the right direction as Blair Kinghorn stretches his legs and now Finn Russell has clipped a lovely kick right into the corner to set up a great lineout opportunity.

Luke Crosbie's return is short-lived as he is immediately replaced by Jack Dempsey.
Scotland 13-7 Wales
Scotland hooker George Turner is back on the field after his yellow card - along with Luke Crosbie - and we have 15 v 15 again.
Scotland 13-7 Wales
Wales build up a head of steam but they're in too much of a hurry as Liam Williams clatters into Pierre Schoeman to concede a penalty.

Wales need to start the second half as strongly as they finished the first.
They have to take advantage of this extra man and apply pressure.
There are going to be plenty of chances in this game, it depends on whether Wales can take them.

Centre George North has come back on the field after his head injury assessment (HIA) which means the Wales backline reshuffle that occurred towards the end of the first half will end.
Josh Adams had switched into midfield from the wing with Alex Cuthbert coming on the right flank.
But North is back and Cuthbert is back on the sidelines.

For Scotland it's almost the same story as last week.
They are doing a lot with very little ball and their defence is holding out.
It's very rare to be able to win games with as little possession as they've had. They're scoring points off scraps.
But Wales have missed a few opportunities.
HT: Scotland 13-7 Wales
Just as they did last week, Scotland have been starved of both possession and territory, but have taken the chances that have arisen.
Gregor Townsend will want a marked improvement in the second half once it's back to 15 v 15.

Wales are playing positive rugby.
It was a very difficult first 20 minutes for them but they've bounced back and they were heading down the tunnel far happier.
They will start the second half with the extra man and mentally they're looking in far better shape.
