A Bulls attack quickly fizzles out and Glasgow sprint away down the pitch. Tom Jordan shows a massive hand-off to the Bulls defender, forcing his way down the right.

The Warriors switch is to the left, and the advantage is coming again. Ruan Nortje is spoken to - three penalties in a row they've conceded.

Down into the corner again.

Another advantage to the visitors inside the home 22m, before Ross Thompson chips it straight out of play.

He won't mind, he's got a chance from the tee which he duly boots over.

Glasgow work their way down into the 22m but the ball is fired at Rory Darge, bouncing off his chest. Another chance goes begging.

Sam Talakai is also on, incidentally, as Patrick Schickerling goes through a mandatory HIA.

Jan-Hendrik Wessels has just put in another monster hit, this time on Tom Jordan. New ribs, please.

Yup, a yellow. A low degree of danger according to referee Andrew Brace and that prevents a red card.

I don't think that will change.

A chance for Glasgow against 14 men.

Andrew Brace has been called across to the screen here, the TMO wants him to look at something.

It's a good spot. Wilco Louw has hit Patrick Schickerling in the head with his shoulder during a tackle.

That'll be at least a yellow, you'd imagine.

Glasgow have the tried the offloading route and they've tried to go direct, but nothing they're doing so far is opening up this Bulls defence.

The door is firmly shut and the Bulls are winning the breakdown battle.

Three more points for Goosen. And Gregor Brown is off injured. Glasgow missing some amount of class back-row forwards now.

That's not what Glasgow fans want to see. Gregor Brown cuts a frustrated figure as he trudges off the pitch, seemingly injured. Euan Ferrie replaces him.

Remember, the Warriors are already without Zander and Matt Fagerson, Jack Dempsey, Sione Tuipulotu and Huw Jones.

Meanwhile in Glasgow, the Warriors get marched back from the throw and then concede a penalty.

Not quite happening for them, and they've conceded another penalty just beyond the halfway line.

Johan Goosen wants the points. Here he goes, from downtown... and he nails the kick from his own half. Behave.

Edinburgh's attack ends in the ball going to the deck. They had the advantage at least.

A bit of afters as Ali Price gets swung around like a handbag on a nightclub dancefloor.

Ross Thompson slots the kick from the 22m line and Edinburgh have the lead in Parma.

Zebre fly-half Giacomo Da Re is also sent to the bin.

Glasgow's back-line isn't quite firing yet. A few times, the ball has come to Tom Jordan at first receiver and it doesn't look like he knows what the plan is.

After forcing the Bulls to touch down behind their own line, they win a penalty and Jordan kicks down to the corner. Opportunity.

Sebastian Cancelliere is pinged for offside and, after going nowhere with the advantage, the Bulls opt to take the points.

Johan Goosen slots the kick and the Bulls draw first blood.

Edinburgh have been inside their own 22m for a lot of this game but they were able to get down the pitch there.

However, Magnus Bradbury was stopped in the Zebre red area and couldn't get the ball away with Andrea Piardi pinging him.

Glasgow try and get their back line firing but Sebastian Cancelliere is lined up and cleaned out by Canan Moodie.

The Bulls try and break, but Ollie Smith intercepts well.

Glasgow might have been held-up there, but they got in behind the Bulls and that'll do plenty for their confidence.

The game was flat and the crowd hushed before that. Not the classic, laced with badness, that we expected but it's early days.

Oh my! Glasgow almost score a sublime try but there's an incredible tackle to deny them.

They make space on the right and Seba Cancelliere tries to force the pass. Stafford McDowall chips the ball into his own hands and gets it inside to Cancelliere, who looks to race for the line...

But Jan-Hendrik Wessels - the loosehead prop - races back to tackle the Argentine, while rolling underneath him to hold the ball up in the try-zone.

Some big carries so far as Glasgow and the Bulls trade possession. The South Africans made it all the way in the 22m before conceding an offensive penalty.

Revenge? What revenge?

We are under way at Scotstoun, with an intensely physical opening to the game.

A delayed kick off in Parma, as there is a minute's silence to commemorate the life of Pope Francis. Under way now.

I think we can all agree we are now officially at the business end of the season, right? This match certainly has a high stakes feel to it.

Glasgow have already secured their top-four finish and the home URC quarter-final that comes with it, but what they really want is a top-two finish that would also bring a home semi-final, should they get there.

Warriors hold a four-points lead over tonight’s opponent’s in the table, but with a trip to Leinster to come in the final match of the regular season – their last visit to Dublin resulted in a 52-0 walloping in the Champions Cup quarter-final – it’s imperative they win tonight to put some distance between themselves and the Bulls.

It’s a rerun of last season’s final and there is a growing sense of a little needle between the sides, which adds to what is a sure to be a fascinating encounter here at Scotstoun.

Bulls head coach Jake White tells Premier Sports: "Every game is [season defining]. People always put a premium on the back end of the competition, but we lost games in the middle.

"Rory McIlroy had a close call many years ago at the Masters and got it right the second time. That's not revenge.

"It was always going to be a game that we'd have looked forward to playing anyway, whether it was the first game of the season or now."

"To win this competition, you'd have to beat Glasgow or Leinster anyway. The first job is done for us, the nice part is to see who we'll play and where."
