Boof! A mighty kick from the 22 by Lucu rolls into touch near the Quins try line.

Will Porter (con: Smith)
What a brilliant try from the scrum-half!
Alex Dombrandt burst over halfway on the left, then fed Will Porter inside him. He chipped the ball up, then collected it after it bounced nicely for him to roll over the line.
They had a quick check for a forward pass from Dombrandt, but it went backwards.
Marcus Smith converts to extend the lead.

Buros appears to have fallen short and then tried to move the ball onto the line.

Full back Romain Buros is buried under some bodies - the onfield decision is 'no try'. They go upstairs...

Maxime Lucu
Textbook stuff from the hosts - they drive from a lineout a few metres out before the scrum half and skipper Maxime Lucu picks uop and dives over near the flag.
But hang on, the TMO is checking for an infringement...

Bordeaux 0-14 Harlequins
Quins are into the 22 and Louis Lynagh spins iot to his left, but Cadan Murley cannot hold it and knocks on. Bordeaux clear, then there is a break for an injury with the rest of the players taking on some fluids.
The Bordeaux players are sheltering under umbrellas to shield them from the sun...

But Quins win the lineout and bravely run it from five metres out. Will Evans does well at a ruck and Smith clears to halfway - Quins have a man advantage at the moment as well with Garcia off.

Some relief for the hosts as they win a penalty just into the Quins half, which they kick for position.

Yes, a clear knock on by Mateo Garcia and Quins have another seven points.
The silence from Bordeaux fans is deafening.

Bordeaux 0-7 Harlequins
Here come Quins again, with Oscar Beard brought down just shy of the line. They spin it right, and Smith's pass looks to have been deliberately knocked on. The ref is having a chat with upstairs...

Bordeaux 0-7 Harlequins
Quins were talking about giving it a go in the preamble this week, and they have certainly done that so far.
But the hosts break out of defence with Romain Buros getting to halfway until he loses the ball in contact.

Will Porter (con: Smith)
What a start for Quins!
Andre Esterhuizen scoots down the lefthand touchline, just staying in play, and then delays his pass just enough for Will Porter to hare over the whitewash.
Marcus Smith pots the conversion but doesn't look happy with how he connected with it. No matter, it's a great start for the English side.

Bordeaux 0-0 Harlequins
Marcus Smith gets us under way with a chip to just short of the Bordeaux 22.
Quins get the ball back and try to run it from halfway but Chandler Cunningham-South spills it.

Former England winger"Bordeaux have had the biggest average crowd in the Top 14 for years,.
"It has just taken them a bit of time for them to get their recruitment right and the blend of the team to make everyone happy, pushing in the right direction."

Bordeaux v Harlequins (15:00 BST)
There's a big, bright yellow hot thing in the sky over Bordeaux. I haven't seen the sun myself for weeks, maybe it's been locked over France.
Anyway, that it is 29 degrees down there might that have an effect on today's game. We'll find out quite soon.
