Celtic 1-0 Ross County
A massive chance for County to snatch a point goes begging.
Jordan White gets his head to a long punt forward, flicks it on to Josh Sims, but the diminutive winger puts his effort over the bar.
Kilmarnock 2-2 Hibernian
Hibs should be ahead! A brilliant ball from Joe Newell picks out Christian Doidge, completely free in the middle, and the striker places his header well wide.
That is an enormous miss from the former Kilmarnock man.
Michael Mellon
After all that - it's given!
That's a goal and two assists for loanee forward Michael Mellon on his Dundee debut.

New Dundee signing Michael Mellon thinks he has added to his two-assist tally with a fine goal from range, but Zach Robinson is ruled offside as the shot flies past the forward en route to the back of the net.
Livingston 1-3 Dundee
An utterly sublime reaction stop from goalkeeper Harry Sharp to keep out Bruce Anderson from close range, followed up quickly by another fine stop with his leg. Keeps Dundee two ahead.
What a game this has turned out to be.
Heart of Midlothian 2-0 Aberdeen
Kenneth Vargas drives a shot inches past the Aberdeen goal!
Hearts have been much better in the second half.
Myziane Maolida
Wow! What a fightback...
It's a simple desperate punt up the pitch that Maolida somehow controls. He could slide it left to Christian Doidge but he shoots straight through the two defenders and it beats the keeper.
Can they get a winner now?!
Image source, BBC SportSt Johnstone 1-1 Motherwell
Blair Spittal steps up with a free kick, perfectly placed just outside the left corner of the St Johnstone box. But his curling attempt at goal fizzles out and falls comfortably for goalkeeper Dimitar Mitov.
Celtic 1-0 Ross County
Celtic win a free-kick on the edge of the box, but Matt O'Riley's shot drifts just wide of the post.
The hosts would love a second goal to make things a bit more comfortable.
Kilmarnock 2-1 Hibernian
A few changes for both sides. Robbie Deas replaces Danny Armstrong as Kilmarnock look to shut up shop.
For Hibs, Harry McKirdy is on for only his second appearance of the season, replacing the felled Jair Tavares.
Does this game have another goal in it?
Zach Robinson
So much for a Livi fightback!
Michael Mellon with another assist on his debut after the loanee chases down a long punt from kick-off, outmuscles his marker and sends a cross into the box.
Michael McGovern is in no man's land, allowing Robinson to tap home Dundee's third.
Need a moment to breathe now...

On his league debut for the club, Yengi puts his penalty low and beyond Harrison Sharp.
But there's already a goal up the other end...
Image source, BBC SportLivingston 0-2 Dundee
Owen Dodgson with a clumsy, late foul on Joel Nouble as the forward enters the penalty area. Spot kick.
Wow!
Kilmarnock 2-1 Hibernian
Corrie Ndaba is given yellow as he catches Jair Tavares on the ankle, hard. The Portuguese winger stays down and VAR is getting involved.
Grant Irvine goes to the screen and it's a quick decision. The defender is off.
Livingston 0-2 Dundee
Dundee midfielder Luke McCowan receives his marching orders for a second yellow card after fouling Tete Yengi.
A lifeline for Livingston...
Lawrence Shankland
A thing of beauty!
He may have lost his form from the spot, but Lawrence Shankland can score from anywhere.
The striker strokes the ball home using the outside of his right boot from the edge of box. Sumptuous.
That's 19 goals for the season.
Image source, BBC SportSt Johnstone 1-1 Motherwell
Harry Paton somehow manages to blast wide from inside the box as Motherwell continue to press forward. A perfectly weighted ball on the right from Stephen O'Donnell fell to Paton, who took one touch to control and a second to put it wide of the St Johnstone net.
Immediately beforehand, Bevis Mugabi somehow contrived to not score after flicking the ball down from head to the outside of his boot but just edging wide of the post in a crowded St Johnstone box.
Kilmarnock 2-1 Hibernian
Hibs almost get a quick second! The ball is pulled back to Emiliano Marcondes in the box, he takes a touch and composes himself, firing low and hard - but goalkeeper Kieran O'Hara produced a good save with his feet.
The hosts are under pressure.
Celtic 1-0 Ross County
Celtic have continued to dominate possession in this second half but have struggled to really carve Ross County open.
Brendan Rodgers has sent on new wing signing Nicolas Kuhn for his debut as the home manager looks to kill this game off.
Joe Newell
My word! From nothing, Hibs hand themselves a lifeline.
It comes from Joe Newell's weak foot, as a cross is cleared to the edge of the box and the English midfielder loops his volley into the top corner.
That's one of the best strikes this season - but will it give Hibs the momentum they need to get back into this?
