Duhan van der Merwe flies off his wing and crashes into Sam Davies. The fly-half does really well to bring the massive South African down, and the ball is knocked on.

Edinburgh have really let themselves down in the key moments.

Richard Cockerill has pretty much emptied his bench. Kennedy, Van der Walt, McKenzie, Ritchie and Dell are all on.

Losing by seven points or less would net Edinburgh a losing bonus point. They've got a line-out inside the Ospreys 22 now.

It's a great counter-attack from Edinburgh and then Henry Pyrgos just drops the ball. It's then just put through the hands and George North is up against Luke Hamilton. It's probably the easiest try he'll ever score.

Edinburgh have got themselves into good field position repeatedly in this second half - largely through the carrying of Hamish Watson and Bill Mata - but they are getting destroyed at the major breakdowns and that lack of accuracy is going to cost them the match.

George North runs the length after another crass Edinburgh error in attack. Two tries for the great man. And surely a knockout blow for Edinburgh. Really poor stuff. Richard Cockerill’s team have created a mountain of problems for themselves tonight.

Nope, it's another maddening error from the visitors. The ball is knocked on at the base of a ruck.

Ospreys did well to regroup and keep Edinburgh at bay. Their reward is a scrum about 15m from the try-line.

Hamish Watson steamrolls a defender and thunders his way into the Ospreys 22. Can Edinburgh strike back?

That North try has imbued the Ospreys with so much energy and Edinburgh are really up against it.

Scott Williams keeps the visitors penned in their own 22 with a grubber kick to the corner. Edinburgh win the line-out, and Henry Pyrgos' kick is half-charged down on its way out. Breathing space for Richard Cockerill's men.

Glorious chance for Ospreys to bag a second try. It's all about George North again, as the giant Lions winger breaks up the right.

The ball is swept to the opposite flank, and Ospreys have numbers. The pass is wayward, though, and flies over the touchline.

You don't see the great Alun Wyn Jones throw too many of those...

There's good numbers in the Edinburgh defence but Blair Kinghorn gets done like a kipper. Van der Merwe doesn't do enough either for me. It's two great steps from North though, he's world-class.

The momentum swings back Ospreys' way, they sweep downfield and Blair Kinghorn has to boot Scott Williams' grubber into touch five metres from the Edinburgh line.

I wonder if the full-back had time to fall on that ball rather than concede the line-out.

As Simon Hickey kicked that penalty, Scotland's most-capped male player Ross Ford replaces captain Stuart McInally at hooker.

His first - highly unenviable task - is tackling George North on the rampage.

Hickey slots the straightforward goal-kick. Not the seven points Edinburgh might feel they merited, but they have the lead once more.

That was excellent stuff from Edinburgh. No-frills, pick-and-go round the fringes, and they come so close to the opening try. McCallum is the man who gets over the whitewawsh, but he's on his back, and the ball is held up. Back we come for a penalty.

This is more like it. Quick, dynamic ball from Edinburgh. Schoeman rumbles forward. Toolis carries on. Then it's Murray McCallum, and suddenly Edinburgh have thundered their way to within five metres of the try-line.

The grind continues. More bashing, more kicking, more errors, more penalties.

There are so many brilliant players on the field but this game has been awful.

Let's have some expansive rugby, please!
