Aberdeen 0-1 St Johnstone
Aberdeen go close twice in quick succession.
A simple goal kick puts Leighton Clarkson in behind, but Dimitar Mitov saves well from the midfielder.
Moments later, Jonny Hayes is played into the box and drags his drive just wide.
Tom Lawrence
What a turnaround in Ayrshire!
Two goals in four minutes. Larence makes this one, too, and finishes it with such aplomb.
It's the midfielder who bursts down the left and links neatly with Oscar Cortes and Cyriel Dessers.
The ball is deflected back into Lawrence's path, and he blasts a fabulous low effort across Will Dennis and home.
Rangers, as things stand, move back to the Premiership summit.
Hearts 1-1 Hibernian
Myziane Maolida, that's outrageous.
A gorgeous flick on the halfway line starts a Hibs attack and ends with Dylan Vente having a deflected shot bend wide.
Kilmarnock 1-1 Rangers
We've seen this picture before...

Hearts 1-1 Hibernian
Zander Clark does well to eventually smother a deflected Jordan Obita cross from the left.
Hibs look lively again.
James Tavernier
Once again, Rangers' captain delivers when the chips are down.
Tom Lawrence is felled 25m out on a powerful run through the middle.
Up steps James Tavernier, and rattles a superb free-kick into the top right corner. Will Dennis got fingertips to it, but couldn't prevent it nestling in the Kilmarnock goal.
Massive moment, that.
Hearts 1-1 Hibernian
Allan Preston
Former Hearts midfielder on BBC Sportsound
I think Hibs will be getting another apology. That's never a penalty in a million years, if it's given for the challenge on Vargas.
It's not VAR that's the problem, it's the people officiating.
Away again at Celtic Park, almost there at Tynecastle...
Kilmarnock 1-0 Rangers
Incredible stop from Jack Butland. Absolutely incredible.
Matty Kennedy is teed up, eight yards out, on the break but Butland leaps to his right to claw it away.
Kennedy has to score. Another blockbuster moment from the Rangers goalkeeper.
Aberdeen 0-1 St Johnstone
Neil Warnock makes a half-time change after a dismal display. Jack MacKenzie replaces Richard Jensen. We'll see if there's a change of shape with that.
We're up and running again at Rugby Park and Pittodrie.
Kilmarnock 1-0 Rangers
Philippe Clement goes to his bench at half-time.
Cyriel Dessers and Ridvan Yilmaz are introduced, with Fabio Silva and Borna Barisic making way as Rangers seek a route back into this one.
That first half will be a huge boost to David Martindale's side after that tough defeat to Ross County at the weekend.
The home side looked pretty comfortable for most of the 45 after Tete Yengi put them in front.
Motherwell's best spell came late on but they couldn't manage to level things up.

No sense of panic on the touchline from Philippe Clement but he was getting more agitated the longer the half went on, with no real sign of his side cutting through a well-organised Kilmarnock.
He has plenty of options on the bench, should he need to turn there. Ridvan Yilmaz and Cyriel Dessers might get a run out shortly after the resumption as Rangers need more, and quickly.

BBC Scotland at Celtic Park
What a 45 minutes that was for Celtic... They were absolutely up for it from the outset. Every time they burst forward they looked full of danger. The home fans are loving it, literally singing in the rain.
Dundee were unlucky with their goal being ruled off side as Curtis Main did well, but with another half to go, Dundee are well and truly down and out.
Brilliant stuff from the champions. Celtic Park is bouncing and little wonder.

HT: Aberdeen 0-1 St Johnstone
Tyrone Smith
BBC Sport Scotland at Pittodrie
Not for the first time this season, the half time whistle is greeted by boos at Pittodrie.
Aberdeen have huffed and puffed but not really created a huge amount by way of clearcut chances.
St Johnstone have offered plenty to this game and will be further emboldened by having something to hang on to in the second half.
Livingston 1-0 Motherwell
So close!
Blair Spittal's effort is inches over the bar... He gets on the end of Stephen O'Donnell's cross but can't manage to get the right connection on it.
Motherwell have a corner though and Shamal George has to make a diving save to keep out Bevis Mugabi's header.
This one has ignited after Hibs had made a dominant start.
Emiliano Marcondes' opener gave the Leith side a deserved lead, but Lawrence Shankland's penalty has levelled a feisty derby.
More of the same after the break, please.

Kheredine Idessane
BBC Scotland at Rugby Park
Kilmarnock have been terrific so far and absolutely deserve the standing ovation they've just had from their raucously delighted supporters.
Yes, goalkeeper Will Dennis made a couple of key saves but Killie also had chances at the other end, with wide men Danny Armstrong and Matty Kennedy causing plenty of problems for Rangers, with the Killie midfield solid behind them and the backline the very definition of organised and cohesive.
The key moment was the early penalty, beautifully despatched down the middle as Jack Butland guessed wrong and dived to his right.
Rangers will have to be better after the break if they're to get anything tonight where Kilmarnock have been as incessant as the Ayrshire rain.
As comprehensive as it gets.
Celtic looked like scoring every time they went forward.
Headers from Cameron Carter-Vickers, Adam Idah and Matt O'Riley put Celtic 3-0 up inside 22 minutes, before Daizen Maeda's excellent left-footed strike and Greg Taylor's close range effort added further gloss to the scoreline.
Curtis Main thought he'd bullied his way through the Celtic defence to pull one back, but was denied by a VAR check which showed him marginally offside.
Right on the stroke of half-time, Callum McGregor made it six after a long spell of Celtic possession.
