Don't worry, we'll provide reaction from Celtic Park as we get it.
But we've got another game on the way...

But we've got another game on the way...
Celtic 4-2 Livingston
And that Kyogo goal seals the win and ends the match.
Celtic into the last four but, boy, they were made to work for it.
Kyogo Furuhashi
And it's given!
Game, set, match.
Celtic 3-2 Livingston
VAR are having a long look at this...
Celtic 3-2 Livingston
Kyogo thinks he's got that fourth but the flag is up.
Top finish as well from the right of the box.
Celtic 3-2 Livingston
Kyogo fires wide from the edge of the box.
If anyone is scoring before this finishes, it's Celtic.
Celtic 3-2 Livingston
Daizen Maeda turns a potential fourth goal off the bar.
Young Daniel Kelly fires wide moments later.
Celtic 3-2 Livingston
Celtic are seeing this out pretty comfortably.
Livi have put in some effort but they look knackered here.
Celtic 3-2 Livingston
Five minutes added.

Rory Loy
Former Dundee striker on BBC Sportsound
Since Livingston equalised, Celtic have been far and away the better team.
I think on the balance of play, that potential winner is deserved.
Celtic 3-2 Livingston
Last throw of the dice for Livi as Bruce Anderson is on for Michael Nottingham.
Meanwhile, Greg Taylor blasts over.
Celtic 3-2 Livingston
Pat Bonner
Former Celtic goalkeeper on BBC Sportsound
Daizen Maeda has been really, really sharp today.
He's in there like a flash to finish.
Celtic 3-2 Livingston
That's an absolute gutter for Livi.
Can they respond for a third time?
They've only got a few minutes to do it.
Celtic 3-2 Livingston
No! Goal stands and what a huge goal it is for Celtic.
Celtic 3-2 Livingston
Oh, is he offside?
Daizen Maeda
Hat-trick!
Tomoki Iwata rolls one to the back post and Daizen Maeda turns his and Celtic's third.
Celtic 2-2 Livingston
James Forrest looks to bend one into the far corner but it's about a yard wide.
Minute 85.
Celtic 2-2 Livingston
Andrew Shinnie is late on Alistair Johnston and Celtic have a free-kick wide on the right.
They work it short but Livi have so many men back there, it's so hard to find a home shirt.
Celtic 2-2 Livingston
Stephen Kelly has been immense for Livi.
He nips in front of his man and clears again at the edge of his box.
Celtic 2-2 Livingston
It's unconvincing again from Celtic and down goes Michael Nottingham.
Looks a clear dive over Joe Hart's leg though.
He's booked for it and rightly so.
