Danny Armstrong plants a corner on top of Inverness goalkeeper Mark Ridgers, and he fumbles the ball.
He takes a nudge in the process, and seems to just claw it back into his grasp before it crosses the line.

There's no quality in Kilmarnock's build-up play.

McInnes has seen enough and is about to make some changes…
Fraser Murray and Scott Robinson raring to go it appears.

FYI, Championship leaders Queen's Park are still being held at 0-0 by Cove Rangers.
In the Highlands, Kilmarnock don't look like scoring. They have 20 minutes...

I hesitate to say Kilmarnock are having their best spell of the game, but they are at least keeping the ball a bit.
And have a free kick...Ash Taylor gets his head on Danny Armstrong's delivery but it's well over.

Inverness could be out of sight.
Cameron Harper puts in another excellent ball, Billy Mckay gets it out in front of him with a touch on his chest, and at the second attempt gets a shot away.
Ash Taylor stood tall to block for Kilmarnock.

How on earth has that not ended up in the back of the net? The cross is put onto the perfect spot. Tantalisingly close.
Inverness CT 2-1 Kilmarnock
Incredible.
Nathan Shaw throws in a couple of stepovers on the left and whips a wonderful cross which runs right across the face of goal, but Sean Welsh can't get the crucial touch for Inverness.
He was inches away.

Can Kilmarnock just not play on grass?

David Carson drives a shot over the bar.
Inverness well on top. Kilmarnock can't get any moves going.

Billy Dodds will be absolutely delighted. But you've got to think the goalkeeper could be doing better there. It's a good enough strike but it goes under Sam Walker. It's a big mistake.

That strike needed no help from the wind!
What a peach from the skipper in the snow.
Sean Welsh
Wow it's gone in this time!
Sean Welsh drives a shot straight down the middle of the goal from about 20 yards, and goalkeeper Sam Walker has a bit of a nightmare and lets it slide past him.
Welsh tears off to celebrate with his team-mates as a blizzard engulfs the stadium!

Jay Henderson drives a low shot off the base of the post!
So unlucky for the Inverness midfielder.

Ah, the magic of the Scottish Cup.
In our own wee winter wonderland, now…
The wind is swirling, too, I wonder what impact that’ll have on proceedings…
Inverness CT 1-1 Kilmarnock
Not much to report in the opening few minutes.
The snow is still coming down. I'm cold just watching it.
Inverness CT 1-1 Kilmarnock
Here we go again.
Can Kilmarnock rouse themselves? Will this game be done in 90 minutes?
Will it even finish, given the snow is now coming down in Inverness. So much excitement. Here we go.
It's goalless at half-time between Championship leaders Queen's Park, and Cove Rangers.
We'll keep you updated with that one too.
