For the second week running, Exeter will pay the penalty for a yellow card. We've only been playing 10 minutes and they've picked up another. It's unusual for them to be so ill-disciplined.

George Horne splits the posts from the original penalty, and Glasgow deservedly lead.

Greg Fisilau has got away with one for mine.

The officials decide Duncan Weir dipped into the contact which drops it down from a red card to yellow.

Weir is off for an HIA, replaced by Tom Jordan.

Exeter's kicking is being punished and Glasgow are prepared to run the ball back at them. It's great play from the Scottish team.

We'll have to wait and see on this tackle from Fisilau - there was a problem with the height. Some worried looks on the faces of the Exeter coaches to our left.

The TMO is having a look at a high shot on Duncan Weir by Exeter number eight Greg Fisilau.

It doesn't look great.

Matt Fagerson has started this game superbly.

The Scotland back-rower spins out of a tackle and powers his way into the Exeter half.

He then offloads brilliantly out of contact and sets Kyle Rowe away down the left.

The hosts scramble back but concede a penalty - they are on the ropes a wee bit here.

A big counter-ruck from Matt Fagerson earns Glasgow a penalty, which Duncan Weir kicks deep into the Exeter 22.

However, young Gregor Hiddleston's throw isn't straight, and the hosts will have a chance to clear their lines.

This Glasgow back line have shown what they're wanting to do. They are very aggressive, and they've opened Exeter up a couple of times already.

The bounce of a rugby ball can be a cruel thing.

Josh McKay looks set to score the opening try after a grubber kick through, but the ball bounces back over his head and Exeter survive.

The visitors bundle Immanuel Feyi-Waboso into touch, but cannot capitalise on the resulting line-out.

Still, a promising start for Glasgow.

Exeter have been excellent all season. This is a game with pressure on Exeter - a win means they almost certainly qualify for the Last 16. In the first few games, against Toulon and Munster, the pressure was off them.

Glasgow are a very erratic side. They lost to Northampton, but won in Bayonne which takes some doing.

It's a lovely still and dry day, it's a cracking day for rugby.

We are under way in Devon...

Jack Yeandle leads out Exeter, Sione Tuipulotu leads out Glasgow, and we're just about ready to go.

Who are you backing to win this one at home? Thumbs up for Exeter, thumbs down for Glasgow.

Exeter coach Rob Baxter tells BBC Devon:

"It's a funny old competition. If these two pool games go wrong, you're under pressure. If you win, you can think your two or three games away from winning the Champions Cup.

"That's when it gets exciting. For this group, they're young and ambitious and their dreams are to win trophies. This is a big game, we're desperate for the last 16, and we're in a very exciting position.

"Last week was as close to a win as you can get. We want to get out the blocks, get a good start and see where the game will take us. Let's play some rugby and see what happens."

Is this Exeter's way of welcoming Glasgow?

Coach Rob Baxter has made five changes to his starting XV for Exeter Chiefs' game against Glasgow Warriors in the Investec Champions Cup.

Centre Rory O'Loughlin comes into the side to partner Henry Slade, a move which sees regular inside centre Joe Hawkins drop to the bench.

Prop Alec Hepburn makes his first start of the season, with hooker Jack Yeandle captaining the side.

Rusi Tuima and Lewis Pearson start in the second row in the absence of Dafydd Jenkins, with Jacques Vermeulen, Ethan Roots and Greg Fisilau in the back row.

Tom Cairns comes into the side at scrum-half, but there will be no Glasgow reunion for Jonny Gray who remains out injured.

Glasgow head coach Franco Smith makes six changes to the side that lost 19-14 to Edinburgh last time out.

Scotland under-20s hooker Gregor Hiddleston makes his professional debut, and Oli Kebble also comes into the front row at loosehead.

Alex Samuel - Hiddleston's former captain at under-20 level - comes back into the boiler room, Henco Venter and Matt Fagerson come into the back-row, with Ally Miller continuing his run in the team with a move to blindside flanker.

Duncan Weir makes only a third start of the season at fly-half in the only change to the Glasgow back-line.
