As mentioned, these four sides are all battling to make it to Twickenham for the final next Saturday.

News that broke yesterday means the capacity has unfortunately been reduced to just 10,000 following the pausing of moving to the next stage of easing government Covid-19 restrictions.

Our rugby union correspondent Chris Jones has more on how tickets originally sold for an expected 20,000-crowd have now been voided.

Enjoying this so far?

Well, don't forget there's the second half and the other semi-final to come later on this afternoon.

Champions Exeter face Sale at Sandy Park, kicking off at 16:30 BST.

More build-up to come on that game later.

Well, well....

Time to take several deep breaths and relax.

That ends an absolutely relentless first half at Ashton Gate.

Bristol in command here and seemingly bound for Twickenham next weekend.

Quins need a huge comeback if they are going to be making the short journey across the A316 to the final on Saturday instead.

Ball spilled out of touch by Quins captain Stephan Lewies as Danny Care tries to thread a pass through a tight space to the left wing.

Sums up their fortunes in this semi-final so far that particular passage of play.

And another stoppage as Quins flanker Jack Kenningham takes a knock to his head when getting on the wrong side of an attempted tackle on Andy Uren.

Quins still pushing to try and get something on the board before the interval.

A rare stoppage in play. In fact, I think the first of the match so far after Danny Care kicks clear to touch and the water boys can get on.

Bristol have been completely ruthless...

Some rare phases of continued possession for Quins until Joe Marchant gets isolated on halfway and Ben Earl forces the turnover.

Terrific work on the floor as yet again they can kick to the corner for another attacking line-out.

Couple of chances go begging for Quins despite gaining a penalty advantage off that scrum.

Alex Dombrandt spills the ball forward in contact with only three metres to go until the tryline.

Harlequins win a penalty in the Bristol 22 after Alex Dombrandt is taken out off the ball.

It's dead in front of the posts, but Quins opt for the attacking scrum as they need a try and then some quickly....

Not to be though for the visitors as Luke Morahan makes a terrific last-ditch covering tackle to force Louis Lynagh out of touch before he could dot down.

Well, have Quins got themselves a score back here?

Louis Lynagh thinks he's in for a score in the corner...

Rare indiscretion for Bristol as Nathan Hughes is penalised for some afters and Quins win a scrum from the restart.

Louis Lynagh the latest Quins player to show some indiscipline as he goes off his feet and gives a penalty away.

Bristol kick it long to touch where Harry Thacker has a line-out on the edge of the Quins 22.

Bristol have won six penalties to Harlequins' nought so far.

Another illustration of just how dominant they've been.

Make that seven as another attacking attempt breaks down for Quins with a knock-on from Jack Kenningham at the base of a ruck.
