Nope, as referee Mathieu Raynal deems that Tom Stewart's throw isn't straight.
Harlequins 21-7 Ulster
John Cooney is wiped out off the ball and Ulster send the ball to the corner once again.
Fourth time lucky?
Harlequins 21-7 Ulster
Things are going from bad to worse for Ulster as Kieran Treadwell is down with an injury.
Fair play to Joe Marler, who realised Treadwell was in pain and stayed over the second row to protect him until play had moved on.
Harry Sheridan is on in his place.

Really disappointing again from Ulster. You just kind of worry now, 14 points down, how do they come back from this without letting their heads go or without Harlequins getting a little bit of energy.

Just a reminder, Lynagh was only called into the squad after Cameron Anderson was deemed unfit at the eleventh hour.
Then, he only got on the pitch after Oscar Beard was forced off with an injury.
Talk about making an impact.
Louis Lynagh (con Smith)
I can't believe what I've just seen!
Quins hack the ball clear from their own 22 and Lynagh is in a foot race with Robert Baloucoune and Michael Lowry.
Baloucoune is first there but he misjudges the bounce of the ball and Lynagh can't believe his luck as he gathers and crosses for his second try!
Smith lands his third conversion of the match.
Harlequins 14-7 Ulster
He got the luck of the bounce, but that was some finish by Louis Lynagh, who wasn't even named in the initial 23.

Marcus Smith is electric and what a joy to watch!

We watch Ulster and they create so many opportunities and they can't do it. Harlequins, that's their second opportunity and their second try.
Louis Lynagh (con Smith)
Out of nothing!
Inside his own 22, Marcus Smith pops a quick pass to Louis Lynagh who barges through Billy Burns on halfway and kicks through.
The bounce beats Jacob Stockdale as he looks to gather and Lynagh can't believe his luck as he picks up the ball and crosses.
End-to-end! Smith converts.
Harlequins 7-7 Ulster
Nick Timoney is almost through with a scything run!
Steven Kitshoff is hit hard in the middle of the park and the hosts manage to turn it over once again!
Harlequins 7-7 Ulster
Tom Stewart and Steven Kitshoff go close...and Quins steal it again as David McCann looks to drive over!
Alex Dombrandt is leading by example! What a steal!

Interesting tactic from the Harlequins that when they're kicking on the right-hand side that they're not kicking out.
Harlequins 7-7 Ulster
Will Evans gives away a penalty deep in the Quins 22 and Burns goes to the corner once again.
Third time lucky for Ulster?

I think we thought for one second that Mike Lowry had missed the chance, but he did really well to stay alive and to put McCann away in the corner.
Great try from Ulster and I think it's fair to say, it's deserved. I think Ulster have played the better rugby.
Harlequins 7-7 Ulster
Another rolling maul, another small win for the Quins as the hosts smother the ball and win the scrum.
Quins are back to their full compliment as Nick David is back from the bin.
Harlequins 7-7 Ulster
Oscar Beard is forced off with an injury in the middle of all that. Will Joseph is on in his place and the replacement immediately gives away a penalty.
Burns kicks to the corner.
David McCann (15 mins)
The big flanker powers over in the corner!
Robert Baloucoune cuts his way through the Quins line and finds John Cooney.
Cooney then finds Michael Lowry, who delays the pass and is almost tackled. He bounces off one tackle and eventually finds McCann, who uses his bulk to drive over.
Ulster did their best to make a mess of it, but they all count! Cooney converts and we're level!
Harlequins 7-0 Ulster
This is very, very scrappy as Ulster now mess up their throw in the Quins 22.
