The flag saves Celtic striker Adam Idah, but he doesn't know he's offside as he gets in behind again and hits a tame finish that's easy enough for the keeper.

First real chance for Celtic as Adam Idah is sent racing into the box before forcing Jordan Smith into a sharp stop.

A long throw into the United box eventually falls to Glenn Middleton on the edge and he smashes a strike off a St Mirren defender.

The ball is then headed on to Ross Docherty in the middle and his shot is easily stopped by Zach Hemming.

Up the other end, Roland Idowu dinks it past Kevin Trapanovski and smashes an effort over the United crossbar.

Celtic have been dominating the ball but are yet to test Jordan Smith in the Hibs goal as Callum McGregor has a shot blocked at the edge of the box.

Hearts swing a corner in and Frankie Kent gets across his man, but can't get himself set to nod into the net.

Wow - Kilmarnock's Bruce Anderson joins St Johnstone's Adama Sidibeh in the doghouse. He's missed an absolute sitter!

Corrie Ndaba bursts from one box to another and then rolls the ball across to Anderson, one-on-one with the goal practically gaping... but he sclaffs it with his left and rolls it wide.

St Mirren have had the better of the early exchanges as United' Jack Walton launches a goal kick straight up to his counterpart Zach Hemming.

First chance for Kilmarnock, with a corner to the back post nodded down by Robbie Deas, but Trevor Carson flies to his right to make a save.

Almost an opener.

Oh my word, St Johnstone should be in front.

A lovely pass from Barry Douglas starts the move and it's then pulled back to Adama Sidibeh on the penalty spot, who has all the time in the world, but fluffs his lines with a wild swipe.

He doesn't make any contact with the ball and a glaring chance goes begging.

Excellent early pressing from Hibs forces rusty Celtic goalkeeper Kasper Schmeichel into a poor pass that goes straight out.

David Gray's men look up for this.

Champions Celtic were clapped on to the pitch by a guard of honour from the visiting Hibs side.

We're good to go now.

We're up and running at Tannadice and Rugby Park. The others won't be far behind...

Simo Valakari said miracles do happen in the build up to this. That's what's required and the need for a win today is non-negotiable.

It's hard to mount an argument to suggest St Johnstone can overcome a six-point margin in the last three games but it is now or never and that might spark a reaction.

Ross County are on a wretched run at just the wrong time.

Six league defeats on the trot doesn't deliver much evidence in their favour as they seek to pull away from the play-off spot. If the margin to their hosts reduces to three, they'll be in deep trouble.

It's in both these teams hands but slipping, particularly for St Johnstone.

It’s a game with little at stake other than pride. The main efforts at Tynecastle now is to ensure they choose the right person to take the club on next season, with Derek McInnes the front runner for the post as things stand

Hearts have lost their last two home league fixtures and haven’t lost three in a row in the top flight since Daniel Stendal was in charge in 2019. Remember him?

Motherwell are looking for a third win in a row in the league for the first time in two years.

Hibernian head coach David Gray tells BBC Scotland: "[Josh Campbell coming in is] just a tactical tweak. It's the fourth time we've been here this season so we know what to expect. A bit more legs in midfield is required.

"Every player will have to be at the top of their game to get a positive result. We've got everything to play for so we have to use that in our favour as well."

On death of former Hibs owner Sir Tom Farmer, Gray adds: "Very sad day for the football club and his family. Everything he did for the football club... He saved the club at a trying time. The family are in the players' thoughts."

Hearts interim head coach Liam Fox tells BBC Scotland: "Blair Spittal picked up a slight thigh injury on Thursday so misses out.

"Craig Gordon has woken up this morning with an issue with his shoulder. So it's disappointing form them but it gives the opportunity for Ryan Fulton and Cammy Devlin to come in and show what they're about."

Asked whether Spittal and Gordon may miss the end of the season, Fox said: "At the moment, possibly, but we'll give it another couple of days and see where we're at."

Kilmarnock manager Derek McInnes tells BBC Sportsound: "A point for us makes us mathematically safe, but we've had three wins in the last four and we want to try and continue that.

"The players have dealt with the situation brilliantly up until now, but they realise there's still a job to do. The last three wins we've had, they've been very calm and resilient, professional and disciplined. We need that again today.

"The structure of the league means rarely can any team breathe easily. Motherwell and Hearts can now, but there's still so much on it for the other four teams."

He was also asked about the link to the Hearts job, but said he'd talk about that after the game. One to stick around for.

There will be a minute's applause as a tribute to former Hearts full-back David Clunie, who passed away last month.

Clunie made more than 350 appearances for the club between 1964 and 1977.

Hibs are wearing black armbands in memory of the club's former owner Sir Tom Farmer, who has died at the age of 84.

The founder of the Kwik Fit garage chain owned a majority stake at Easter Road for 28 years before selling up in 2019.

Celtic scored 106 Premiership goals under Brendan Rodgers in their 'invincibles' campaign of 2016-17.

They're on 103 this season.

The club record is 114, netted in 2022-23 on the watch of Ange Postecoglu.

At home, they have scored 58. The last time they got more was 2003-04 when they hit 64 at Celtic Park.
