A massive win for Worcester and surely they're safe from the drop now?
Quins miss the chance to break into the top four on afternoon when they never got going.

What do I know? Tom Heathcote misses and the game's still alive.
Quins going for an audacious attempt to run it from their own line for the win.
Harlequins 15-21 Worcester
That's probably going to be it for Quins as they fail to roll away on the floor with Worcester only 15 metres out.
Tom Heathcote with a chance to wrap it up for the Warriors.
Harlequins 15-21 Worcester
Another great response from Worcester who get themselves deep into Quins territory and make sure they eat up the seconds and the phases in the process.

We're back to six points again in no time at all as Ben Botica takes advantage off the tee as Worcester are penalised for hands in the ruck.

And that could be a massive kick for Worcester.

Can still go either way in the battle for both the top four and survival.

More sloppiness in the scrum from Worcester and Quins with a penalty and Botica the chance for a shot at goal.
Harlequins 9-18 Worcester
More stalemate stuff here at The Stoop, but Quins force an infringement at the scrum in their own half and Botica boots downfield for a line-out.
Harlequins 9-18 Worcester
Kicking exchange eventually results in an offside against Worcester and a chance for Ben Botica to get a range-finding kick deep into Worcester territory.
But, Quins waste the chance as it's overturned at the line-out on the edge of Worcester's 22.
Harlequins 9-18 Worcester
Still no points in this second half as we approach the final quarter of this contest.
Plenty of sighters for both sides, but no clinicism and composure as yet.

Harlequins 9-18 Worcester
Tom Biggs the man to make a big burst into space this time for Worcester, but Charlie Walker is back across just in time to bring him down along the 22.
More scrappiness follows as Quins clear their lines and still can't find some fluency to their play.
Harlequins 9-18 Worcester
Possession changes hands frequently from sloppy mistakes, but neither side really grabbing this second half by the scruff of the neck yet.
Harlequins 9-18 Worcester
Quins do finally turn it over deep inside their 22, but an attempt by Ross Chisholm to burst out of his own half for a counter-attacking try is scuppered by a wayward pass out wide to Henry Cheeseman.
Worcester line-out 30 metres from their opponents' line.
