Four matches in Championship (15:00)
Aberdeen 0-0 Dundee
Angus MacDonald has stopped a certain goal.
Scott Tiffoney gets away from Nicky Devlin and cuts the ball to Lyall Cameron at the back-post. He's four yards out but MacDonald spreads himself and somehow blocks the ball on the line.
Unbelievable from the Dons defender!
St Johnstone 0-1 Kilmarnock
Marley Watkins twice fails to prod the ball into the back of the net, with strong blocks from Ryan McGowan and David Keltjens thwarting the Kilmarnock forward.
Liam Polworth's laced volley follow-up from 20-yards is then pushed wide by Dimitar Mitov.
A brief break as Saints stand-in skipper Daniel Phillips goes down for the second time in as many minutes.
Celtic 2-0 St Mirren
It's all Celtic now and Zach Hemming had to block a Greg Taylor drive with his knees before pushing wide a Reo Hatate effort at the front post.
Celtic 2-0 St Mirren
Kheredine Idessane
BBC Scotland at Celtic Park
Where was this Celtic in the first half? Urgent, creative, energetic, clinical. Lovely move, leading up to a perfect cross from Alastair Johnston, right onto the forehead of Kyogo Furuhashi who couldn't miss from close range.
The songs of celebration ring round a completely transformed Celtic Park, with the home fans relaxing on the cushion of a two-goal lead.

Cammy Devlin almost grabs his second goal of the afternoon.
Jorge Grant picks him out with a lovely cross, but on the slide the Hearts midfielder stabs the ball wide.
Aberdeen 0-0 Dundee
Tyrone Smith
BBC Sport Scotland at Pittodrie
Its all been Dundee in the second half so far.
Worryingly for Aberdeen, the Dark Blues play makers, Cameron, McCowan and Scott Tiffoney are seeing a lot of the ball.
Gavin Gallagher
Ben Dempsey
Hearts 4-2 Livingston
Lawrence Shankland lashes a shot off the bar, and Kenneth Vargas steams into convert the rebound...except it bounces over his head and Livingston clear!
St Johnstone 0-1 Kilmarnock
Chances galore at McDiarmid Park since the break.
Adama Sidibeh sends Nicky Clark in behind the Killie defence with a neat knock-on header, but the Saints number 10 wildly blasts his volley high and wide.
Hearts 4-2 Livingston
Tete Yengi has just been replaced by Bruce Anderson, and then there's something clearly said in the dugout.
The Livi striker is then shown a second yellow card and has to go down the tunnel!
Luckily for the visitors the substitution had been made, so they have 11 men on the pitch.
Malachi Fagan-Walcott
Kyogo Furuhashi
Game over?
What were we saying about the winds of change?
Alistair Johnston is again the provider and the right-back's deep curling cross finds the head of Kyogo Furuhashi to power past goalkeeper Zach Hemming.
That's 16 for the season for the Japan striker.
Celtic 1-0 St Mirren
St Mirren are struggling to cope with the wind of change that is driving piles of rubbish as well as Celtic bodies into the visiting penalty box.
Two forced changes won't have helped.
Jaden Brown replaced left-back Scott Tanser at half-time and, moments into the second half, forward Greg Kiltie was forced off, with Lewis Jamieson his replacement.
Celtic 1-0 St Mirren
Kheredine Idessane
BBC Scotland at Celtic Park
You could feel that goal coming - what you didn't know was how good it was going to be. An absolute rocket into the top right hand corner of Zach Hemming's goal by Reo Hatate, after a nice first touch to steady himself.
Celtic Park exploded with noise - the fans have been waiting for something to cheer since 3pm! The half-time team-talk pays almost instant dividends for Brendan Rodgers. Is that Celtic's first shot on target?

Very cool finish from Myziane Maolida, who slots his penalty into the bottom right corner.
Motherwell 0-0 Hibernian
Will Fish on the deck, Willie Collum points to the spot.
There's nothing in that, is there?
It looks like the most innocuous challenge from Stephen O'Donnell as the Hibs defender lets the ball roll and tries to spin, but the decision stands.
Motherwell 0-0 Hibernian
Theo Bair thought he had put Motherwell in front but the flag goes up for offside.
It was a cool finish beyond David Marshall.
Seeing the replay, it looks tight but Willie Collum soon gets confirmation that the striker raced away a shade too early.
Celtic 1-0 St Mirren
It's a different Celtic now and it should be 2-0.
Alistair Johnston is the provider again, but the unmarked Yang Hyun-jun makes a mess of his attempt to fire home.
Motherwell 0-0 Hibernian
Elie Youan attempts to make up for that first-half miss as he drives into tests Liam Kelly, who dives to palm the shot away.
Joe Newell sends his signature long throw into the box and Blair Spittal does so well to beat Martin Boyle to the ball and head it out for a corner.
The corner comes in and Rocky Bushiri lunges in front of Blair Spittal as the home player clears. Referee Willie Collum reaches into his pocket for a yellow card to show to Bushiri and there's a bit of afters as a furious Spittal pushes the Hibs man to the deck.
He's booked, as is Martin Boyle for his part in the scrap that followed.
Spittal definitely kicks Bushiri, but the Hibs defender was playing for the contact.
