Oh, VAR check for a potential handball...

What I thought might happen is indeed playing out.

Killie need a goal so are piling forward, with Kyle Magennis and Kyle Vassell both going close.

While at the other end, Hearts look dangerous going forward. Just ask home keeper Will Dennis, who watched helplessly as Stephen Kingsley's left-footed dipper came back off the crossbar.

Much, much better. Well done

Alan Forrest whips in a stunning cross.

No-one is there, but Danny Armstrong wasn't aware and puts it behind for a corner.

Luckily for him, it comes to nothing.

The home fans and home captain are furious.

Frankie Kent handballs it after being tripped by Kyle Vassell. Correct call to give Hearts a free-kick.

Kyle Magennis is everywhere.

He gets to the bye-line and pulls one to the edge for Kyle Vassell and his shot across goal is pushed away by Zander Clark.

Stephen Kingsley cushions a lovely effort on the bounce from the edge of the box.

But it comes bouncing off the bar. So unlucky.

For some reason, it says Killie have scored at the top of this page.

They definitely haven't, right?

Derek McInnes will be encouraged by the start his side has made to this second half.

Another sight of goal for Kyle Magennis as Toby Sibbick has a wild swipe at a clearance.

It runs for the Killie man who slices wide from a tight angle.

This is far, far better from Killie.

Kyle Vassell holds the ball up and sends in Matty Kennedy, who lays one back for Kyle Magennis to cut across beautifully.

But it bends just wide of the far post.

Killie keep coming as Danny Armstrong fires one in from the right.

It just won't fall for a man in blue and white though.

Another deep free-kick comes into the Hearts box and eventually falls for Robbie Deas.

The Killie defender snatches at it and loops it over.

Hearts clear the resulting free-kick to Matty Kennedy, who makes a right mess of his half volley.

The ball then comes back out to the edge for David Watson and he slices high and wide.

That's a half chance.

Stephen Kingsley can't believe Steven McLean has given a free-kick against him.

The Hearts left-back wins the ball, but it's one of they ones you don't get away with now.

Back under way at Rugby Park.

Peter Haring is on for Hearts midfielder Cammy Devlin.

Must be an injury of some kind?

Let's get it right. This hasn't been great. Far from it. But the goal was.

Lovely little lay-off from Lawrence Shankland, right into the path of recalled midfielder Jorge Grant, whose curled finish was perfect for the bottom right-hand corner.

Before that, Matty Kennedy had impressed in the opening 10 minutes at the other end, forcing a fabulous save from Zander Clark to keep Hearts level.

And, well, that's pretty much it. But the fact Killie now need to chase the game gives us hope for after the break. In any case, it's a cup tie. Neither side will care about the quality.

They just want a place at Hampden.

If you get to the final and get to win the trophy, they don't remember the scrappy games you need to win to get there.

Steven [Naismith] will obviously be the happier of the managers now, but will [Derek] McInnes look to change his shape now?

He'll be thinking about how to get a step ahead, maybe going with another striker up the pitch.

Warming up for a second-half appearance, Del?

The game's been pretty even at times, but the Killie boss' side failed to register a shot on target in that first period.
