David Martindale throws the dice with three changes.

On come defender Tom Parkes and midfielders Steven Bradley and Stephen Kelly.

Off go Mohammed Sangare, Scott Pittman and Jamie Brandon.

This is how Celtic play. They've been moving well off the ball, they've been giving lots of options to the player on the ball.

Hatate is good at that. He doesn't stick to a position. He moves all over and that gives the opposition problems.

I cannot understand how Scott Bain cannot see Joel Nouble. You don't have that much time in the middle of the box when Livi are high up the park.

He's got away with that - massively.

So close to a quickfire reply for Livingston and it's so nearly a booboo from Celtic's substitute.

Scott Bain delays a kick, Joel Nouble nips in to block, but the striker's attempt to lob the rebound over the goalkeeper is a few yards over the crossbar.

Livingston threaten immediately, but Mohammed Sangare can only prod wide from a low cross into the penalty box.

Celtic get the second half underway. Down to 10 men but defending a one-goal lead.

Will Livingston make them pay for that Joe Hart red card? Thumbs up below for yes, thumbs down for no.

It's a split second between a brilliant bit of play and poor play. For me, I don't think you can be hyper-critical [of Joe Hart]. The thing I'd be looking at is the defensive set up. Celtic have been caught out on three or four occasions by a simple ball over the top.

Livingston have to put long balls over Lagerbielke. His body position at times is all wrong and I would be telling Livingston that's what they have to exploit.

I'm not worried about Joe Hart. He was just trying to help his centre-halves out. I wouldn't put it down to poor decision-making.

Joe is a very experienced keeper. He impressed me during the week. He held his hands up after the free-kick against Betis, took the heat off Kyogo - who could have had questions asked about what he was doing in the wall. That was leadership. Other keepers would make excuses.

He comes up with big saves at times. He made a big save against Bruce Anderson today.

Celtic, after the penalty, had started to motor. They were more like their old selves - a lot more interchange, a lot more freedom middle to front. Greg Taylor was influential and instrumental. It looked like it could be a long afternoon for Livingston.

Then the red card completely changes the game.

Reo Hatate's spot kick separates the sides.

It's been an incident-packed first half and the Celtic procession you might have expected after that early breakthrough hasn't happened.

And the red card for goalkeeper Joe Hart means the visitors' lead is on a knife edge.

Scott Bain again in action.

This time, the goalkeeper rises to nip the ball off the top of Mohammed Sangare's head and grab it at the second attempt as a ball finds the midfielder deep inside the Celtic penalty box.

Scott Bain makes his first save.

It's fairly comfortable as he is down clutch a Ayo Obileye snap shot from 18 yards bounces awkwardly in front of Celtic's sub goalkeeper.

Since Celtic went down to 10 men, there's little sign that they're enjoying less possession or space.

Livingston will have to find a way to make their superior numbers pay if they want to take anything here.

Celtic are down to 10 men, but it is the visitors who continue to dominate possession.

Livingston, though, are increasingly dangerous on the break.

Game very much in the balance.

Mohammed Sangare is involved again for Livingston.

The big midfielder lumbers dangerously across the Celtic penalty box, but his shot is wildly over the crossbar.

That's two yellow cards and a red for Celtic players before even half an hour has been played. Alistair Johnston and Liam Scales are now walking a tightrope for the rest of the match. Joe Hart has long since walked to the dressing room after being ordered off and replaced with Scott Bain. Should be a fascinating hour from here.

Scott Bain is on for a rare Celtic appearance, with winger James Forrest being sacrificed by Brendan Rodgers.

Livingston don't make the most of their free-kick outside the penalty box as James Penrice finds the side netting.
