Breath-taking stuff...

Kilmarnock manager Derek McInnes is sent to the stand.
He's having a laugh to himself as his offence appears to be coming out of his technical area.
Zak Rudden
Wow! The 10 men look to have snatched a point at the death.

Wow.
After what seemed like an eternity, that Alex Grieve goal has been disallowed for offside.
Having seen a replay, I'm not convinced. It's the third goal St Mirren have had chalked off this afternoon.
Hibs secure a comfortable win in Nick Montgomery's home debut as head coach.
Lewis Miller and Dylan Vente with the goals.

Game over? Or is it?
It's all about the wing-backs again for Stephen Robinson's side, as Scott Tanser's deep cross is right on the money for Ryan Strain.
Strain nods it back across goal to Alex Grieve and it's the simplest of finishes for the Kiwi striker.
But, wait, there is a VAR check...

Danny Armstrong
The 10 men are behind!
It took a while coming, but Kilmarnock are finally ahead. Andrew Dallas had plenty of time to fire the ball across goal. Goalkeeper and defender missed it, and Armstrong was left with the easiest of finishes.

Teenager Rory Whittaker is denied a dream debut goal as his shot is blocked by the legs of goalkeeper Dimitar Mitov.
Fellow Hibs substitute Christian Doidge is first to the loose ball, but the striker's shot is stopped by a defender near the goal-line.
Robbie Crawford
Dunfermline have been on top and comfortable - but Morton are back in it.

Hearts are desperate to get something out of this.
They are throwing bodies forward in search of a breakthrough, but St Mirren are holding firm - just.
What a save that was from Zach Hemmings from Cammy Devlin though. The slightest fingertip and just past. Vital.
St Mirren 1-0 Heart of Midlothian
Brilliant stop from home goalkeeper Zach Hemming, who gets down to his right to tip Cammy Devlin's low drive round the far post.
It was a superb flick over the top from Lawrence Shankland to play Devlin in and the Australia midfielder must have thought he had scored.
Dundee 1-1 Kilmarnock
Danny Armstrong powers his way to the edge of the box, holds off a few challenges and somehow feeds Kyle Vassell, but the striker's shot only ripples the side netting.
Kilmarnock are doing their utmost to find a way to goal against the 10-man hosts, but they just can't find that moment of composure.
Jermaine Hylton
Wow! Part-time Arbroath extend their lead over hosts who have title aspirations.

St Mirren have the ball in the back of the net for the third time this afternoon, but Mikael Mandron's effort is chalked off, just as Greg Kiltie's was in the first half.
Not really sure why that has been disallowed.
