St Johnstone 0-0 Rangers
And now we're into the second half in Perth.
Jordan White
A quick freekick plays Billy McKay in down the right and his ball in sets off a game of all out pinball in the St Mirren box.
The ball eventually floats out to Jason Naismith who powers a header towards goal and Jordan White does brilliantly to flick it beyond Jak Alnwick.
Lewis Ferguson
Terrible defending and the Dons take the lead.
Niall McGinn's corner is headed on by Andrew Considine and Lewis Ferguson is on the line to prod home despite having his shirt pulled.
That's the midfielder's 10th goal of the season and he remains Aberdeen's top scorer despite not finding the net since October - against Celtic.
Aberdeen 0-0 Celtic
Bit of a blow for Aberdeen as they lose Ross McCrorie after he goes down injured for a second time.
Celtic striker Odsonne Edouard fell awkwardly on the former Rangers player's ankle as the Aberdeen man conceded a free-kick.
McCrorie tried to play on for a couple of minutes but is replaced with 17-year-old defender Calvin Ramsay.
Aberdeen 0-0 Celtic
Gary Woods is called into action for the first time in his first Aberdeen start.
The on-loan Oldham goalkeeper is a bit theatrical as he punches clear a rather unthreatening David Turnbull free-kick.
Aberdeen 0-0 Celtic
After Livingston's failure to beat Hibs at Easter Road, Aberdeen now know they will qualify for the Europa Conference League if they can beat Celtic.
But they host a side who they have not beaten in 13 meetings since May 2018, including four this season, losing the latest three without scoring. Indeed, they have not beaten the visitors from Glasgow at Pittodrie in 10 games since February 2016.
Manager Stephen Glass got off to a winning start as his new charges edged out Livi on penalties after a 2-2 home draw in the Scottish Cup on Saturday.
It extends their winning run to three games, an improvement on a sequence of one win in 10 beforehand, but the former Dons winger will no doubt have spotted things that still need improving.
Mark O'Hara's first-half strike is enough to give Motherwell a first derby win since August 2019.
The hosts made it difficult from themselves when Ronan Hughes saw red for a late challenge on 33 minutes.
They fought hard in the second half but defeat leaves Brian Rice's two points adrift at the foot of the table for now.
Well that was a lot more nervy than it needed to be for Hibernian, but Jack Ross' side will be playing European football next season and that's the main thing.
Despite Jay Emmanuel-Thomas' late consolation from the spot, first-half goals from Kevin Nisbet and Martin Boyle ensure victory over Livingston at Easter Road.
That stretches Hibs' lead over Aberdeen to seven points.
David Martindale's side, meanwhile, have just one win in their last nine league games.
Hibernian 2-1 Livingston
Kevin Nisbet misses a glorious chance to seal the points for Hibs, as his one-on-one is saved by Max Stryjek.
Kilmarnock 0-0 Dundee United
Despite making seven changes in order to rest some of their key players, Dundee United have made a bright start at Rugby Park.
Liam Smith puts in a great delivery from the right, but no tangerine shirt could get on the end of it.
Aberdeen 0-0 Celtic
Celtic have had most of the early possession, but it is Aberdeen who create the first big chance.
Lewis Ferguson's looping header from a Ross McCrorie chip to the edge of the penalty looks to be creeping into the top corner before goalkeeper Scott Bain palms it clear.
It falls to Callum Hendry, but the on-loan St Johnstone's striker's shot is blocked wide by right-back Jonjoe Kenny.
Hamilton Academical 0-1 Motherwell
It's the away side that are doing all the attacking in the closing stages as Devante Cole directs a close-range shot from a tight angle into the side netting,
It's been an entertaining and even first half in Perth, with play coursing from end to end.
St Johnstone made a blistering start, going close through Liam Craig and Guy Melamed, the latter being denied a goal for offisde.
Rangers had good opportunities when Jack Simpson headed over and Scott Wright was stopped by clever goalkeeping from Zander Clark.
Hamilton Academical 0-1 Motherwell
Accies have four minutes to rescue anything from this one.
Defeat will leave them two points adrift at the bottom with Kilmarnock and Ross County still to play tonight.
Aberdeen 0-0 Celtic
Celtic run out onto the Pittodrie pitch in the knowledge that, for just about the first time in 10 years, they have nothing to play for in their concluding matches of the season - and nothing to celebrate at the end of them.
Sunday's defeat by Rangers was not only painful because it was against their city rivals but because it ended their four-year stranglehold on the Scottish Cup - and it came against the side who had already wrestled the league title out of their hands.
Celtic have still only lost twice in their last 12 outings, and one in six since John Kennedy took over as caretaker after Neil Lennon's exit, but it is a long time since the Glasgow side have gone three away games without a win - and without scoring.
Can they shake themselves out of the limbo-like state that has afflicted them while they await a new manager to be chosen?
We're up and running at Rugby Park and Pittodrie. Won't be long up in Dingwall...
Hamilton Academical 0-1 Motherwell
Mark O'Hara again at the heart of Motherwell's attacking play, but he will be disappointed he hasn't hit the target.
Barry Maguire feeds the former Dundee man who is in acres of space on the right side of the box, but his driven effort is well wide.
Jay Emmanuel-Thomas (pen)
Another confident penalty and Livingston half the deficit with a few minutes remaining as Jay Emmanuel-Thomas steps up and sends Ofir Marciano the wrong way.
Hibernian 2-0 Livingston
Kyle Magennis, just on for Hibs, mis-controls in his own area and hacks down Jay Emmanuel-Thomas. Really slack play from the substitute.
A late lifeline for Livingston.
Hamilton Academical 0-1 Motherwell
Mark O'Hara nods down for Stephen O'Donnell who drives the ball across the face of goal.
If anyone gets a touch on that, it's 2-0.
