Dundee United 1-1 Hearts
Yellow card from Scott McMann as Josh Ginelly skips away from him and the United defender catches him.
It's not the first time a late challenge has gone in, there's been a bit of edge in this game.
Michael Smith
A goal from an unlikely scorer!
Cammy Devlin slips the right-back in behind and it's a calm finish from the Northern Ireland international.
However, he's absolutely clattered by Ryan Edwards as he hits it, and he's down receiving treatment. Robbie Neilson is not happy.

Dreamland for Hibs!
It's way too easy from a Livingston point of view. Elie Youan swings a cross in from the left and Kyle Magennis wanders into the box unnoticed to head home the simplest of chances.

A bad head knock involving Arnaud Djoum and Stephen Kingsley. Picture the Iranian keeper during the World Cup... Kingsley has come off worse, and he's replaced by Toby Sibbick.
This isn't the first time Hearts have gone to Tannadice and ended up the walking wounded. When they travelled there in March, they had to make three first-half substitutions.

A very good game, with both sides really going for it. This is a fixture which usually produces plenty of goals - we have had one so far, and it feels like there will be more to come.

Chris Cadden
Two goals in the space of 74 seconds for Hibs!
Chris Cadden gets into a wee bit of space down the right-hand side, and he fires a rasping low drive beyond Ivan Konovalov into the far corner.
Lee Johnson has a big grin on his face - it's been a while since that was the case.

Ryan Porteous fires a direct free-kick past the Livingston wall, Ivan Konovalov can only parry it into the path of Kevin Nisbet, and his shot finds the back of the net via the near post.

Steven Fletcher almost doubles his tally. Dylan Levitt sweeps a superb cross right onto the striker's head and he forces a good save from Craig Gordon.
The resulting corner is whipped in and Ian Harkes nods a header onto the roof of the net.
What a game it's been so far.
Hibernian 0-0 Livingston
I don't think Ryan Porteous and Jason Holt will be exchanging Christmas cards tomorrow.
The Hibs defender was unimpressed by Holt's red card challenge on Kevin Nisbet, who is only just back from long-term injury.
Image source, SNSAnother home win for the Buddies, who scored two of their three penalties and knocked in a late goal when Aberdeen keeper Kelle Roos was up for a corner.
Aberdeen took the lead with a cracking goal from Matty Kennedy, but it all started to unravel when Anthony Stewart was sent off for conceding the first of those spot-kicks.
The Dons have lost three games since the campaign resumed and still they remain third in the table.

Dundee United 1-0 Hearts
Josh Ginnelly is inches away from finding the top corner. The winger paced through before cutting onto his right, but his whipped effort is just over the bar.
No equaliser just yet.
That's 11 league wins in a row for Celtic as they restore their nine-point lead at the summit of the Scottish Premiership.
Two goals for stand-in full-back Reo Hatate and two for striker Kyogo Furuhashi.
Drey Wright with the consolation goal for the visitors, while there was a late red card for Celtic sub David Turnbull.

Sensational drama.
Kelle Roos goes up for the corner, gets a touch but can't fire it on target.
St Mirren clear, but Jack MacKenzie gifts the ball to Greg Kiltie who side-foots into an open goal from 40 yards.
Game over!

Kevin Nisbet wheels away in celebration after tapping home Chris Cadden's shot-cum-cross, but his delight is cut short by the linesman's flag.
Hibs are testing the 10 men of Livingston now.

Time for some late drama?

The Celtic midfielder catches goalkeeper Remi Matthews with a very high boot.
Kevin Clancy goes off to check the monitor and comes back brandishing his red card.

A really classy finish from Steven Fletcher to give Dundee United the lead. Great composure and poise to fire that into the net from 20 yards.

After all the drama and being down to ten-men, it's Aberdeen who are thrusting forward in search of an equaliser.
They've come very close in hitting the bar before Jack Mackenzie's effort was diverted.
And then somehow they failed to convert when Ryan Duncan flew in but couldn't get it on target from close range.
Where has this been all afternoon?
Steven Fletcher
A long ball over the top seems to be dealt with, but Steven Fletcher's volleys takes a wicked deflection off Kye Rowles and it evades Craig Gordon.
After a lengthy VAR check, it's given!
