Gus Warr goes low and looks to be short of the Quins try line, the referee says no try but they are checking.

Quins have been much improved since the resumption, and this feels like much more of a contest now.

But Sale have hit back and are camping out deep in the Quins 22. Luke Cowan-Dickie wants to take a quick tap, but a kick to the corner gives Sale a chance from a lineout five metres out.

Jack Kenningham gives the Quins fans something to cheer, getting over the ball and winning a penalty that is kicked downfield to give the hosts a lineout on halfway.

Rodrigo Isgro follows it with a neat chip kick that earns another lineout, edging Quins down the pitch further, before Marcus Smith hoofs a penalty into the wind to make some ground on the left hand flank.

Alex Dombrandt infringes in front of the posts, and George Ford has the simplest of chances from in front of the posts, extending the lead to 19.

George Ford gets the second half going, high to the right and into Cadan Murley's breadbasket.

Nick David's try-that-wasn't followed on quickly from an interception that almost saw Quins go over in the opposite corner.

They'll have to take those threats from late in the first half into the second if they are to claw their way back.

If you haven't been with us throughout the day, where have you been???

This is the fifth and final last-16 tie of a busy Saturday in the Champions Cup.

Bath, Glasgow, Toulon and Toulouse have all joined Northampton in the quarter-finals today.

You can read reports of today's action on the BBC's dedicated rugby union page.

Will it be Harlequins or Sale who progress tonight?

Sale have had 71% possession playing into the wind for the first half, although they have played against 14 players for the past 10 minutes or so.

There is barely enough time to restart, and the referee blows for the break.

There are quite a few boos from Quins fans, but if they had had that try given against them, they'd be just as unhappy.

After a review that took too long - after the conversion - the try is chalked off!

Nick David's elbow landed out of play just before he touched down and Sale's 16-point lead is restored.

It is worth remembering that Sale have been playing into the wind, and they are now a good chunk ahead with a man advantage for the rest of the half.

And they'll have the breeze after the break.

Quins are down to 14, as Will Evans goes down off his feet to irk the referee and receive a yellow card.

George Ford could go for goal, but kicks for the corner instead.

Quins infringe right in front of their posts, 15 metres out and George Ford lands the kick with no alarms this time.

It's a bit more old-school than the try-fests of earlier so far. One for the purists.

A sight I love to see - a second row charging down the wing!

Sale's Ernst van Rhyn rampages down the right hand side but Bryn Bradley does superbly to tackle him into touch.
