Onto Bristol then, Irish fly-half Harry Byrne is set to make his first appearance after joining on loan from Leinster.

Byrne will lead the Bristol attack after joining the Premiership side on a three-month deal from the Irish province.

Kalaveti Ravouvou returns to the midfield at outside centre, while Benjamin Elizalde is named at full-back.

Prop Max Lahiff will make his 99th Bristol appearance as one of six changes in the pack with only captain Fitz Harding and Viliame Mata retaining their place in the starting XV.

We'll have the full line-ups next...

Time to hand over the live text duties as we bring you coverage of La Rochelle against Leinster and Bristol against Benetton.

Toulon next face Sale next Sunday and Harlequins will host Glasgow on Saturday.

Last 16 qualification still very much alive for Quins but they may need something from that game.

Toulon secure their spot in the last 16, with Harlequins unable to take anything from the game.

Harlequins have a scrum with less than a minute to go. A losing bonus point looks unlikely unless they score straight away.

Alex Dombrandt nicks the ball and tries to find Nick David but the pass can't be picked up by the winger. Sums up the day for Harlequins.

Toulon in full control as they continue to play out the clock.

Marcus Smith races clear down the wing after an offload from Alex Dombrandt. However, there isn't enough gas left in the tank to go the length of the pitch as he is chased down.

Dan Biggar's first touch is to punt a penalty into Quins' 22. Is there another score in this one?

Former Wales fly-half Dan Biggar is on. Paolo Garbisi has shifted to 12.

Toulon have done so well to regain control of the game when it looked like Harlequins were on the charge. Three wins from three looks likely.

The live texter curse as Marius Domon's pass is behind Gael Drean. If that went to hand a try was on.

Marius Domon scoops up the kick through and finds a nice touch. The Toulon full-back has been excellent. France have plenty of options there but he could well soon find himself regularly in the mix.

With 20 minutes left, Harlequins would fancy scoring two tries to nick a point. It is more than doable.

Toulon go through some phases and charge into Quins' 22. It has felt a while since they've been down here.

Alex Dombrandt wins a penalty and into the corner Harlequins go. Another quick try and this could get tasty.

Quins break up the field from the restart. It looks like they've found some extra energy from that score.
