What a cup tie we've got here!
Celtic 2-2 Livingston
Goodness me. A huge chance for Livi to take the lead.
Michael Nottingham meets a wide free-kick and Joe Hart stops it with his foot.

That is an unbelievable finish. Incredible from Tete Yengi.
It's magnificent from the striker. Joe Hart had no chance.

Tete Yengi does unbelievably well. Top class finish.

Goal stands.

VAR check for offside...
Tete Yengi
What. A. Finish.
Celtic give it away so cheaply and Jamie Brandon slips in Tete Yengi.
Liam Scales looks like he's recovered, but Yengi hits a stunner on the spin and it fires into the far corner.
Wow.
Celtic 2-1 Livingston
Nicolas Kuhn is giving Cristian Montano a terrible time.
The German winger wins another free-kick, which comes to nothing in the end.
Celtic 2-1 Livingston
Superb stuff from Nicolas Kuhn again.
He drives and lifts a lovely ball through to Paulo Bernardo, who can't find the target at the near post.

Former Dundee striker on BBC Sportsound
Tete Yengi's hold-up play has been magnificent.
That is exactly the type of chance he scored in the last round against Partick Thistle. A huge opportunity.
Celtic 2-1 Livingston
That should be 2-2!
Stephen Kelly puts in a perfect cross and Tete Yengi has got to hit the target, but he heads wide.
Huge chance.

It could have been a hat-trick for Maeda.
Great work again from Kuhn.
Celtic 2-1 Livingston
Nicolas Kuhn gets to the bye-line and puts another dangerous ball in.
Someone gets a touch then it seems to go through the legs of both Adam Idah and Daizen Maeda.
Celtic 2-1 Livingston
Michael Nottingham does well to win the ball for Livi and off he goes.
But he runs into a Celtic ball and the break ends.
Celtic 2-1 Livingston
Away we go again.
HT: Celtic 2-1 Livingston
Pat Bonner
Former Celtic goalkeeper on BBC Sportsound
Nicolas Kuhn has really contributed in this first half.
He's probably having the best game of his Celtic career so far.

BBC Scotland at Celtic Park
It appears not a single member of the Livingston coaching staff has headed down the tunnel and into the dressing room with the players.
They're all just gathered round a screen looking over some footage. I'm not sure I've ever seen that before.
And you'll be able to watch highlights of today's action - and Aberdeen's win yesterday - on Sportscene later.
BBC One Scotland at 22:30 GMT.
As it stands, Celtic are set to join Aberdeen in the last four.
The semi-final draw will take place after Monday's final quarter-final between Morton and Hearts - live on BBC Scotland.
Celtic 2-1 Livingston
A Daizen Maeda double, either side of Dan MacKay's leveller, sees Celtic go back down the tunnel in the lead.
A pretty decent cup tie, to be honest.
