A worrying sight for Glasgow and Scotland, as Scott Cummings is forced off with an injury to his arm.

He would likely start against Italy, if fit, next weekend.

Alex Samuel is on in his place.

This Glasgow team are great out of possession for the first few phases, but are slightly more susceptible when teams keep hold of the ball.

That's what Quins will look to do - go through multiple phases.

Glasgow win another lineout penalty - this time on halfway - and Tom Jordan kicks the visitors into the opposition 22.

It's a messy lineout, Quins are pinged for obstruction and Glasgow have a chance to clear their lines.

It's almost the perfect start for the home side, who have numbers out wide, but Glasgow full-back Josh McKay makes a crucial interception to prevent the try.

He has no though, and Quins force a penalty which Marcus Smith kicks to the corner.

Referee Pierre Brousset peeps his whistle, and Quins fly-half Marcus Smith gets us under way.

The players are out at The Stoop - Quins in their traditional home colours, and Glasgow in their change strip of sky blue and white.

Kick-off is just around the corner...

The hosts are third in the table, level on points with fourth-placed Stormers and Sale Sharks in fifth, while Racing 92 are a point behind in sixth.

However, Quins' points difference advantage over Sale means a bonus-point win over Glasgow would almost certainly seal a place in the knockout stages.

Glasgow are already guaranteed a home tie in the last 16, but could yet top the group if they better Toulon’s result against Sale - that match is on Sunday.

Glasgow Warriors head coach Franco Smith has made five changes from the win over Racing 92 last time out.

Euan Ferrie replaces Gregor Brown in the second row, while Jack Dempsey makes his first club appearance since October, preferred to Jack Mann at number eight.

In the backs, Jamie Dobie comes in for George Horne at scrum-half, and there are starts for Stafford McDowall and Kyle Rowe in place of Sione Tuipulotu and Kyle Steyn.

Tuipulotu was always going to be rested for this game, we’re told, but Scotland’s captain is an injury doubt for the Six Nations having sustained an upper body injury in training this week.

Harlequins make three changes for tonight's game.

Lock Stephan Lewies returns to the starting XV, while flanker Chandler Cunningham-South is recalled to the back row.

Ben Waghorn replaces injured centre Luke Northmore to make his full European debut as Quins look to seal their place in the last 16.

Harlequins: Green; David, Beard, Waghorn, Murley; Smith, Porter; Baxter, Walker, Lamositele, Chisholm, Lewies, Cunningham-South, Kenningham, Dombrandt (capt).

Replacements: Riley, Jones, Kerrod, Launchbury, Lawday, W Evans, Care, J Evans.

Glasgow: McKay, Cancelliere, Jones, McDowall (capt), Rowe, Jordan, Dobie; Sutherland, Matthews, Z Fagerson, Ferrie, Cummings, M Fagerson, Darge, Dempsey.

Replacements: Hiddleston, Bhatti, Talakai, Samuel, Brown, Venter, Afshar, Weir.

All eyes now turn to south-west London, as Harlequins host URC champions Glasgow in Pool 4.

Let's have a wee look at the teams.

It's been an all-action afternoon in Europe's rugby competition, so let's just take a breath and remind ourselves what's happened to this point.

In Pool 2, Bristol Bears suffered an agonising 33-26 defeat by Clermont Auvergne and are out of European competition.

Thomas Ceyte's try in the sixth minute of overtime denied Bristol a draw and consigns them to bottom spot, meaning they will not make the Challenge Cup.

There was also an impressive 32-25 win for Italian side Benetton against La Rochelle, while Leinster proved too strong for Bath in Dublin, earning a 47-21 win.

Bath held a 21-19 lead at half-time, but Beno Obano's red card swung the momentum towards the hosts, who ruthlessly took advantage.

At Franklin's Gardens, Tom Seabrook's wonderful hat-trick helped Northampton Saints edge out Munster 34-32 in a thrilling contest.

Northampton finish top of Pool 3 and are guaranteed a home tie in the last 16 and the quarter-finals, should they get there.

In Pool 3's other game, Bulls swept Stade Francais aside 48-7 in Pretoria.

Watching Alex Mitchell receive some attention during Northampton's win over Munster earlier will have been a concern for England fans.

The scrum-half suffered a bang on the knee but was strapped up and remained on the field.

Speaking to BBC Radio 5 Sports Extra, Northampton director of rugby Phil Dowson said: "Alex got a knee to knee [collision] which is painful without, hopefully, being any structural damage."

Player of the match Robbie Henshaw speaking on RTE: "We got there in the end after a slow start.

"Credit to Bath, they put us under pressure from the get go.

"We're getting there [in attack]. We're always working on it, a few errors here and there but lots of positives to take from it."

So with all of Pool 2 in the books, today's results see Leinster and La Rochelle finish in the top two spots.

Benetton's victory over Ronan O'Gara's men sees them finish in third and Clermont squeak through in fourth.

Bath drop down into the Challenge Cup while Bristol will only have domestic rugby to focus on from here on out.

There's the final whistle in Dublin and Bath will be playing Challenge Cup rugby come the spring.

Very much the game of two halves in the Aviva Stadium.

When leading 14-0 early on, and 21-19 at half time, the visitors will have felt they were in a real position to advance to the last-16.

Leinster's bench impact, and crucially the second yellow shown to prop Beno Obano, turned the game decisively however.

Leinster finish the pool stages top of the group on 18 points and will have to wait and see what seeding that delivers.

Leinster have a line-out five metres out and are looking to add insult to injury for Bath.

They target Snyman but the ball goes loose.

Maybe they should have had Ringrose in there again after all.

Already with an unfamiliar number 14 on his back this evening, Garry Ringrose is up and taking the ball in the line-out.

Not something we expected to see today in all honesty.
