Hearts are growing in confidence, they've been so much better since adding pace out wide.

Gerald Taylor's cross is deflected on target and the goalkeeper parries it, then has to make a smart save as Stephen Kingsley belts in a shot.

Yan Dhanda is on for Liam Boyce as Hearts start to go for this.

They need to.

Over the 70-minute mark now as Hearts try to push for a leveller.

Are they getting one?

Outstanding from Gordon, he's kept Hearts in this.

Look how much he stretches himself.

Craig Gordon. That's it.

The ball is slipped to Daniel Vasulin bang in front of goal with just the Hearts keeper to beat.

You know the rest.

Gordon rushes out and makes the stop with his arm.

Blair Spittal and Yan Dhanda are warming up as Kenneth Vargas gets attended to by the medical team.

The Costa Rican forward looks fine to continue though.

It feels so disjointed tonight for Hearts.

James Penrice curls in a delightful cross, but Liam Boyce can't get on the end of it.

Hearts are pushing.

Derek McInnes and his players are now standing in a line, applauding the fans who are showing their appreciation.

Wholesome stuff.

That's that. Kilmarnock's European journey is over.

The fans are right behind their team on the full-time whistle.

They've given it a good go but just fallen short.

Silky stuff from Kenneth Vargas, as he nutmegs Vaclav Jemelka and draws the foul.

The free kick is swung in, but Plzen head away.

Ooft, another Gerald Taylor cross, for a moment, looks like it might drop on target.

But it's the wrong side of the post.

Scottish football, man.

A slight delay in restarting as a hole in the net needs to be repaired.

Big chance as Matty Kennedy sweeps a low cross in, and David Watson goes down under pressure.

The referee wags his finger at the midfielder. I think he's going down before the contact is made.

I doubt VAR will have a long look at that.

Hearts striker Lawrence Shankland tells BBC Scotland: "The boys will be pleased. The important thing is we haven't lost a goal.

"Hopefully we can sustain our attacks a wee bit better and make chances in the second half.

"Kenneth [Vargas'] pace is dangerous on the counter."

Hearts haven't had any momentum in the game.

It's been tough in terms of creating chances, and it's because they haven't had any dominant possession in the game.

Nathan Trott leaves one on Stuart Findlay as he collects a free-kick into the box. It caused a bit of a rammy but tempers have calmed.

Now, here's some changes. Bobby Wales and Liam Polworth are on. Marley Watkins and Joe Wright are off.

Hearts are going too long, too often. They are vacating the midfield, but when it goes long there is nobody to play off of.

We said Hearts needed a fast start but they haven't had it, which has allowed Plzen to settle.
