The experienced Gareth Davies is now on at number nine for Scarlets but his clearance kick is a modest one.

Northampton attack and now have another penalty 10 metres out. They've gone for the corner.

Quins have stretched their lead to 10 points, thanks to a superb try from Tyrone Green!

A lineout near the tryline results in the ball being spun to the right, before slight of hand from Chandler Cunningham-South flips it up to the full-back, who crashes over by the posts.

Marcus Smith converts, and as it stands La Rochelle are being dumped out of the competition with Leicester progressing to the last 16.

THIS IS NOT A DRILL!

After being decimated all day in this department, Scarlets win a scrum penalty.

In a pop music reference that only people of my generation will truly appreciate, it's now 'all Saints'.

Henry Pollock shows tremendous strength to surge 30 metres upfield but mercifully for Scarlets, after the ball goes wide Blair Murray pulls off a jackal at the breakdown and wins a penalty.

A score looked inevitable there.

James Ramm evades several tackles to put Saints on the front foot but Anthony Belleau, somewhat wastefully, opts to kick across field and the ball only finds touch.

I said moments ago it's been five scrum penalties in favour of Northampton so far - well make it six.

Once again the away pack is sent half way back to the Severn Bridge and as a result, are now pinned in their own half.

Archie Hughes launches a box-kick and some pin-ball follows, before Scarlets are awarded a scrum 20 metres from the Northampton line.

The away side are back up to 15 players, so let's see how this one goes...

Anthony Belleau does the honours and Scarlets clear their lines.

Incidentally, the penalty count in the first half was 9-1 in favour of the hosts. Bear in mind five of them came from the scrums.

To state the blindingly obvious, Scarlets must address that to have any hope here.

So, if things stay this way, Northampton will secure second place in Pool Four and in theory, an easier path to Bilbao in May.

For Scarlets, nothing less than a win is enough to keep their European adventure alive. Do that with four tries, then it's the last-16 of the Champions Cup.

Manage a win without a bonus point, and they'll join three other Welsh sides in the Challenge Cup knockout stages.

Their season hinges on the next 40 minutes.

Speaking on Premier Sports, former Welsh international Tom Shanklin said: "The issue for Scarlets is the scrum. They have to find a way to sort that out.

"But if they can match that first half display in the second, then they are still right in this game."

And breathe.

You wouldn't have seen a more intense 40 minutes in this competition this season.

Scarlets, roundly written off before kick-off, haven turned up meaning business. But Northampton have weathered the storm and through a powerful scrum and the brilliance of Edoardo Todaro, remain on course to finish second in the Pool.

A superb end to the first 40 for Quins, with Caden Murley diving over by the left corner flag for a fine try converted almost from the touchline by Marcus Smith.

The fly-half had earlier got Quins onto the scoresheet with a penalty.

A win would give Quins a home tie in the next round.

Anthony Bellau goes cross-field and finds winger Ollie Sleightholme.

He too chips ahead but his effort lacks control and drifts into touch.

Scarlets are taking their time over the lineout now, you sense that with 14 men, they are playing for half-time.

Like night follows day, another Scarlets scrum means another Northampton penalty.

The referee has seen enough and Scarlets prop Kemsley Mathias is the guy in the firing line. He's off for 10 minutes.

Saints might be trailing, but their front row is having a field day here.

For the fourth time they win a scrum penalty and it gives Anthony Belleau the chance to boot them into the Scarlets 22.

Again though, the move breaks down in midfield as Fletcher Anderson makes a big hit.

At the risk of going ridiculously early, get involved you lot.

Thumbs up if you think Scarlets can keep this up and get a shock win.

Thumbs down if you're expecting a blow-up, and a home win, in the second half.

Jac Davies is back in his feet, albeit with a bandage around his head. He's fine to carry on.

But from the Scarlets scrum, it's another Northampton penalty followed by some handbags with Mr Pollock heavily involved.

No chance of this final pool game petering out quietly folks.
