Glasgow win a penalty after Ulster infringe setting up a maul.

That's a big win for the Warriors, and it's met with a huge cheer from the stands.

A big carry from Ulster's number eight Nick Timoney takes Ulster to within 5m of the Glasgow line.

The hosts do well to scramble and force the ball into touch, but they will need another strong defensive set as Ulster will have the throw inside Glasgow's 22.

Do you ever get the sense that certain forwards don't like backs?

It's a team game, Peter!

It's their strength from this year. They get set very quickly, and get it moving very quickly.

Look at the backs in there trying to steal the glory.

Now a penalty goes the way of the Warriors, and Tom Jordan kicks to the corner.

Catch and maul, you'd imagine...

The rain continues to tumble down, and a handling error from Ulster gives Glasgow a scrum deep in opposition territory.

This is a fantastic position to attack from...

Losing the two lineouts in Glasgow's 22 has cost Ulster their attacking platform.

They have to find a way to fix that.

Back on the park, Scott Cummings does superbly to steal another Ulster lineout, just when the visitors were building some momentum.

It's like he's never been away.

You might, just might, be living slightly in the past there, Peter...

Why do scrum-halves get so much protection? It's like goalkeepers in football - bring back the old days where you could barge them into the goal

I hate the fact that these little people get so much protection.

Oooh, that's nearly very clever.

Glasgow are ready for Ulster to kick to touch, but Billy Burns catches everyone in black and blue by surprise by aiming a cross-field kick towards Jacob Stockdale.

However, the bounce of the ball evades the big winger and rolls into touch.

Meanwhile, some thoughts from Peter Wright on scrum-halves...

Ulster's first foray into Glasgow territory is halted as Scott Cummings climbs highest to pinch the visitors' attacking lineout.

An excellent box-kick from Jamie Dobie completes the exit.

No, they can't.

Sione Vailanu knocks-on in the slippery conditions, but Ulster's clearance is straight down the throat of Cole Forbes, and the Warriors will come again.

Jeff Toomaga-Allen goes off his feet at the breakdown, and Tom Jordan kicks the resulting penalty into the corner.

Can they take advantage of this early pressure?

Glasgow are on the attack right from the off having stolen possession.

Some strong carries from Jack Dempsey and co take the hosts into Ulster's 22.

Tom Jordan kicks high into the night sky, and we are under way...

Let's see who you're backing at home - thumbs up for Glasgow, thumbs down for Ulster.

The picture doesn't quite do it justice, but it's chucking it down at Scotstoun.

It's nice and toasty at my desk though, and I've got a cup of tea for company - kick-off isn't far away.

Glasgow can leapfrog Ulster in the URC table with a bonus point win tonight, and coming into this game unbeaten in nine, they will fancy their chances.

Moving up to third in the league would be a real statement of intent from Franco Smith's side.

Ali Price is clearly not in the top two for Scotland, and is John Cooney soon going to be a Scotland player?

Ali Price is right up against it to be one of the three scrum-halves for the World Cup.

He will be deeply frustrated to not start tonight.
