Adam Hastings sends another peach of a kick down into the Edinburgh 22. Bill Mata returns from his 10 minutes in the sin bin, and we are going to have a video review with the TMO.

Fraser Brown is down receiving treatment after being thumped by Scotland rival Stuart McInally.

Goodness me, the breakdown is an absolute war out there.

Glasgow look for all the world like they're building towards a try. Their go-to men, Scott Cummings, Tommy Seymour, Huw Jones, are making wounding carries in the Edinburgh 22.

Hamish Watson is having none of it. Ben Toolis chops down Cummings as his rival lock embarks on a massive charge. Watson wedges himself over ball, withstands the blue-shirted torpedoes flying in to dislodge him, and wins a big, big penalty. Edinburgh clear.

A change at scrum-half for the visitors. The very tidy South African Nic Groom comes on for Henry Pyrgos, who we reckon is going for a head injury assessment.

Glasgow decimate the seven-man Edinburgh scrum and will have the chance to apply pressure as Hastings kicks to the corner.

A fleeting glimpse of the sort of blockbuster attack Duhan van der Merwe and Darcy Graham can contribute.

Van der Merwe swats aside defenders like a buffalo running through bluebottles, then Graham blazes up the right flank and slaloms into Glasgow territory.

A few moments later, the big South African is back fielding another Warriors kick, but spills in the tackle, and Glasgow will have a scrum on halfway.

Blair Kinghorn gets the second half going for 14-man Edinburgh. They've got about eight minutes minus Bill Mata to last before the giant Fijian returns from the naughty step.

Here come the teams again. Forty massive minutes ahead.

Ten penalties conceded by Glasgow in that first half to Edinburgh's five. The home side have had a little over a third of the possession and territory and lost several line-outs, but still go in level at the break.

Edinburgh will feel they ought to at least be ahead given their statistical dominance.

Tetchy, try-less, error-strewn. The first half has been a bit of a grind and there's nothing to separate the teams at the interval.

Two penalties apiece from Adam Hastings and Simon Hickey. A sin bin for Ruaridh Jackson and one for Bill Mata right on half-time. Very, very little in this. Not a game for lovers of champagne rugby but it certainly hasn't been dull.

That's massive for Edinburgh. Zander Fagerson, who has won two scrum penalties already, concedes one for binding on the arm of Pierre Schoeman. Opportunity gone.

Edinburgh number eight Viliame Mata is sin-binned. The officials reckon the Fijian was offside when he made an otherwise brilliant tackle to thwart what looked like a scoring Glasgow move.

The Warriors are going for the scrum against the seven-man pack with the clock red. This is the last play of the half. Can they make it count?

That kick, however, from Mark Bennett, is less than impressive. The former Glasgow man ought to know Scotstoun well, but sends his punt out on the full.

Last minute of the half. Glasgow line-out on the Edinburgh 22. Here come the home side...

And I tell you what, that's a glorious punt from George Horne too. The scrum-half scampers back, covering the area normally filled by the sin-binned Jackson, and returns Henry Pyrgos' box-kick with a super touch-finder of his own.

Edinburgh attack again just inside their own half, and Glasgow concede their ninth penalty of the game. Jackson, however, is back on, and Glasgow have not suffered any real damage while he's been off.

Boom. Belter. That's how you strike a ball. Glasgow, down to 14 men, but level with five minutes of the first half remaining.

Just as scrum connoisseur Peter Wright furnishes us with those stats, Glasgow win a scrum penalty. Pierre Schoeman penalised for the second time up against Zander Fagerson.

Adam Hastings gets the driver out and goes for a long-range, 40m boomer.

The stats show Edinburgh are gaining the upper hand at Scotstoun. They've had 69% possession, over 70% of the territory, and forced Glasgow to make twice as many tackles as the visitors.

More worryingly for Dave Rennie and the Warriors coaching staff, Glasgow have already shipped eight penalties.

No mistake this time from the Edinburgh fly-half.
