Ach, that's a shame. Edinburgh loose-head Pierre Schoeman is done for an early engagement, Glasgow win a free-kick, and we don't get to see what the Warriors had up their sleeve from that bizarrely configured set-piece.

Right. This is interesting. Glasgow are putting in to a scrum 5m from their own line. Rob Harley, the blind-side flanker, and Sam Johnson, the centre, have swapped places.

Harley is standing in midfield by the posts and Johnson is packing down in the back-row.

That's big moment for Glasgow. I'm not convinced Rob Harley was operating within the bounds of the law there, but tell me a good back-row forward who does.

The flame-haired flanker absolutely loves making a nuisance of himself and he disrupts the Edinburgh drive to win Glasgow a scrum.

Edinburgh go for the drive. Glasgow infringe, Scott Cummings hauling down WP Nel from the maul.

Kinghorn to the corner again...

Oh, hello. Here come Edinburgh again. They win a penalty just inside the Glasgow half and Blair Kinghorn's massive punt takes them to within 15m of the visitors' line.

This will be one for the bruisers...

Another Glasgow penalty. Another Hastings punt. This time, a safely secured line-out. The white jerseys begin to make headway into the Edinburgh 22.

Glasgow look to respond immediately to that stunning Graham try. Stuart McInally is pinned on the wrong side of a ruck and concedes a penalty.

Hastings kicks Glasgow down to the home 22. Their line-out has been decimated by the Edinburgh pack so far. This is a big one... and they lose it again! Ben Toolis the pilferer this time. Massive set-piece issues for Dave Rennie.

Edinburgh are putting themselves under pressure again now. Nic Groom launches a box kick up the left touchline but he launches it a little too far left and it's out on the full.

Glasgow have a line-out but again, Edinburgh pinch it, and suddenly Duhan van der Merwe is rampaging out of defence.

Absolutely nothing in this so far. Seventeen minutes gone, no score.

No, is the answer. Glasgow can't maul their way over. Ruaridh Jackson tries the chip to the corner for the racing Ratu Tagive, but he's put too much on it and Edinburgh have a 5m line-out.

Warriors try to outfox the Edinburgh pack by not engaging with the drive, but they don't get it quite right and concede a penalty. Easy out for the hosts, but another solid defensive set from Edinburgh as they keep Glasgow out again.

Now it's a huge chance for Glasgow to strike.

Hamish Watson is back covering for Edinburgh but his pass only finds Adam Hastings, and the flanker is then penalised for not rolling away.

Warriors boot to the corner. Can they convert?

From the line-out that follows, Edinburgh target Huw Jones in defence. The centre is frequently criticised for his tackling but he brings down hulking Bill Mata with a fine chop tackle.

Mark Bennett spies space in behind the Glasgow defence but his probing kick flies out on the full and Glasgow launch an attack of their own.

Edinburgh get the upper hand in the scrummage. They win a free-kick, then back their set-piece again and earn a penalty. Blair Kinghorn hoofs the home side into Glasgow territory.

Warriors go through the phases, but Edinburgh stand firm. Very firm. Some big old hits go in and Oli Kebble's pass to Ruaridh Jackson doesn't go to hand. Edinburgh scrum. That's a big psychological boost.
