St Mirren 0-0 St Johnstone
Lewis Jamieson is causing more havoc for St Johnstone after being body checked by Daniel Phillips in shooting range.
Caolan Boyd-Munce overrules Greg Kiltie to have a go from 25 yards, but his weak effort allows for a simple collection from Dimitar Mitov.
Eamonn Brophy
What a hit!
Simon Murray pings a wonderful pass out to the right-hand side of the box and Eamonn Brophy lets it bounce before smashing the ball past Shamal George from a tight angle.
Sensational from Brophy, County in firm control.

Aberdeen have worked their way into this after a bright start by the home side.
Kilmarnock will feel they've had the better opportunities, though, none more so than that early Kyle Vassell effort that struck the post.
The Dons had Jamie McGrath to thank for being in the right place to divert that Stuart Findlay header off the line.
You just feel Kilmarnock marginally have the edge right now in the final third.

Rangers 1-0 Hearts
Lawrence Shankland gets his first sight at goal.
It's a half-chance by the striker's standards, but he drags it into a Rangers body inside the area.
Hibernian 0-0 Dundee
A booking for simulation around the halfway line, and it's for Amadou Bakayoko. To make matters worse, he could have played the ball over the top to an unmarked Lyall Cameron, who would have gone clear through.
Dundee manager Tony Docherty will be livid.
Rangers 1-0 Hearts

Rangers are thoroughly enjoying their afternoon, and little wonder. They're playing well, while Hearts have been incredibly sloppy with what little possession they've had. There's a nervousness about them at the back that belies their recent record, in which they've not lost since 9 December at Pittodrie.

Kilmarnock 0-0 Aberdeen
Killie looked certain to hit the front there.
Stuart Findlay rises high above the rest at a corner and thunders a header across goal, only to watch it punted off the line.
Home crowd were already on their feet.
St Mirren 0-0 St Johnstone

The contrasting scenes in the two dugouts below me is very interesting. St Mirren manager Stephen Robinson is like a cat on a hot tin roof - he cannot stand still. He's pacing up an down in his area while waving his arms around in either frustration or in a bid to encourage his players.
As for St Johnstone counterpart Craig Levein, he's a picture of calm. He's standing at the back of his area studying the action in front of him and having the odd word with his coaching staff.

St Mirren 0-0 St Johnstone
Nimble footwork from Lewis Jamieson thrusts the forward inside the visitors' penalty area but St Johnstone skipper Liam Gordon races across to clear the danger with a terrific, clattering challenge.
Proper defending that.
Ruari Paton
Ruari Paton's 17th goal of the season puts the visitors in front at Tannadice.
Image source, BBC SportEamonn Brophy
A big goal and it's a horrendous mistake by Mohammed Sangare.
Simon Murray was trying to play in Eamonn Brophy, but Sangare is there to intercept, but he lets the ball slip under his studs.
Brophy races through and calmly slots beyond Shamal George.

It's been a physical contest so far at Rugby Park.
Image source, SNSHibernian 0-0 Dundee
VAR gets a regular mention these days and earlier ruled that there had been no handball by Dundee's Owen Beck against Hibernian.
Image source, SNSRangers 1-0 Hearts
It's clearly offside in the end, but how does Cyriel Dessers not score anyway?
Ridvan Yilmaz has a shot spilled by Zander Clark before the striker fails to beat the Hearts keeper with two unconvincing attempts on the rebound.
Rangers 1-0 Hearts
What a strike.
Stunning technique from James Tavernier as he drills one first time to the far corner but again Zander Clark makes a top stop.
St Mirren 0-0 St Johnstone
Not had a shot in the past 10 minutes at the SMiSA Stadium as both teams struggle to make an impact in the final third.
St Mirren certainly holding more possession but crafting next to nothing with it in the early stages. The visitors will need to start showing more, with both Nicky Clark and Adama Sidibeh failing to impact the game thus far up top.
Kilmarnock 0-0 Aberdeen.
And now Nicky Devlin is down holding his head. Walking wounded for Aberdeen at the moment.
Again it's Marley Watkins involved, but he doesn't look convinced there was a foul in there.
Not sure he's endearing himself to his former support...
Rangers 1-0 Hearts
Cyriel Dessers rolls Kye Rowles on the halfway line then races all the way into the Hearts box.
The Rangers striker chops on to his left foot and forces Zander Clark down to his right.
Ross County 0-0 Livingston
Ooft, County midfielder Victor Loturi drives a vicious shot on target from 25 yards, and goalkeeper Shamal George has to push it over.
A few minutes later and Jordan White heads just wide.
Hibernian 0-0 Dundee
Hibs are finding a bit of joy down the left. Myziane Maolida has gotten free twice and sent in dangerous crosses that have been blocked at the last second.
Nothing else to trouble the goalies.
