Wasps will be grateful to have the ball back in hand here, albeit inside their own half. They'll be glad to hear the half-time whistle.

A disaster for Wasps. The restart is spilled straight out of play, Northampton have the line-out, work the rolling maul and get themselves a penalty try. An unbelievable two minutes or so of game-time for the visitors.

Stephen Myler this time converts and we're all square at the Gardens.

For the record, Stephen Myler has finally taken his conversion and drifted it wide of the posts. Game on again.

The 22-year-old is, at last, lifted onto a stretcher and carried off to rapturous applause. His two tries have got Northampton back in this contest but, of course, the primary concern is for George North's welfare. We'll bring you any updates as soon as we get them.

All the while, George North is still down in the corner receiving treatment. This is turning into a long delay.

Of course, there was some attention surrounding North following Wales' Six Nations opener against England, in which he took a couple of knocks to the head. Fingers crossed it's nothing too serious here.

It's a red card for Nathan Hughes! What a big call that is from the referee.

The big number eight argues his case as he trudges off, but it'll count for little. Wasps are down to 14 men.

Northampton Saints are back in it, and it's George North again! The ball is kicked long, brilliantly offloaded to North, who shimmies and then slides over.

Now, North has been caught late here by the knee of Nathan Hughes as he crossed the whitewash. The Wales winger looks in a fair bit of trouble. And was it an intentional blow? The television match official is going to have a look...

And he splits them with relative ease. Ice cool from Alex Lozowski.

Dylan Hartley is putting poor Craig Maxwell-Keys under so much pressure here, the Northampton captain constantly in the referee's ear.

It's not doing the hooker many favours though, as the away side win a couple of penalties in quick succession, the latest for offside.

Alex Lozowski will go for the posts...

But he's just won them back over again by awarding Northampton a penalty as they turn the ball over just a couple of metres from their own line.

This has been non-stop, a great watch.

The young referee is not endearing himself to the Franklin's Gardens crowd here. George North is adjudged to have put a high tackle in on Christian Wade - though you could argue their height differential makes it quite hard not too.

Nonetheless, Wasps head for the corner and are on the attack.

And, eventually, one of those infringements will result in some Northampton Saints points. Stephen Myler slots the simplest of chances from right in front of the posts and reduces the deficit to nine.

Wasps do earn themselves some respite, turning the ball over, but a couple of infringements later and Northampton are in possession and knocking on the door once more. They're around eight metres from the Wasps line here.

His good work has allowed Saints to make their way up the field, too, and they now have a line-out of their own deep inside the Wasps half.

That's excellent from George North, however, winning Northampton a penalty at the breakdown after planting himself brilliantly over the ball. That boy is difficult to shift.

Everyone is going Wasps' way here. A poke through from Rob Miller flicks off a Northampton hand before going to touch, and so the visitors have a line-out deep in enemy territory.

What was it I was just saying about Alex Lozowski? Well, it turns out he's just as handy with ball in hand as he is with his boot.

The youngster puts on the after-burners around 15 metres out to break the line, before feeding Christian Wade to slide over in the corner. The television match official has a little look but the England wing got the ball down without a problem.

It's an excellent conversion from a tight angle too. What a first quarter from Wasps.

I can't imagine the penalty count is looking too hot for Northampton at the moment. Scrum-half Lee Dickson is caught offside now and Wasps head for touch. The line-out is good and the rolling maul is on...

Alex Lozowski has started quite nicely here, putting a couple of smart kicks from hand in too. He finds touch to force Northampton back into their own half, but the line-out is good and they clear up field.

This has been a frantic start. It's really sloppy from Northampton straight from the restart, giving away a penalty and allowing Alex Lozowski another kick at goal.

It's two from two for the 21-year-old, stepping in for the injured Andy Goode tonight. Wasps are ahead by five.
