Now then, it's a yellow card for Ross Callachan, but should it be more?

It's exactly the type of cynical challenge that John Lundstram was sent off for at Easter Road earlier. Ryan Alebiosu is sprinting away on the counter and Callachan chops him down, scissoring Alebiosu's legs.

A nasty one.

Former Aberdeen hero Andy Considine is booked for a high tackle on Vicente Besuijen.

He's perhaps lucky not to have been sent off against the club he represented for 19 seasons - after clattering Besuijen earlier on.

County still looking more likely to score, albeit without really threatening Sam Walker's goal too dangerously.

Callum Johnson with the latest chance, looping a header straight into the keeper's arms.

Aberdeen midfielder Leighton Clarkson looks a player. He threads a magnificent ball in behind St Johnstone centre-back Alex Mitchell, but Bojan Miovski can't connect at full stretch.

Motherwell's Blair Spittal sizes up the goal but fires well wide of the target.

It's a sign of how the game is going now as the hosts begin to enjoy more of the ball, but the threat they have offered in the final third has been disappointing.

Macedonian striker Bojan Miovski thought he'd scored his fifth Aberdeen goal as he stoops to turn home an excellent diving header.

But the linesman raises his flag for offside. It is very tight indeed.

Chances at both ends.

Josh Sims goes down in the Killie box under a challenge from Lewis Mayo, but nothing is given. The visitors counter and Oli Shaw is played in on the left in acres of space - but he fires his shot straight at Ross Laidlaw.

It has been all St Mirren in the opening 25 minutes.

Joseph Ayunga was nearly in behind the United defence but a late offside flag halted the attack.

The hosts look like a side decidedly lacking in confidence.

Vicente Besuijen has had a lively start to this game. The diminutive Dutchman flings in an acrobatic overhead kick, but his connection with the ball isn't true.

The visitors are doing most of the attacking so far.

Best chance of the game for Motherwell as a free-kick finds Ricki Lamie at the back post, but his diving header can only direct the ball wide of the post.

Big chance for Jordy Hiwula...

The ball is whipped in from the right, flicked on by Callum Johnson, and arrives on the volley at Hiwula, but the County striker lashes it into the ground and into Sam Walker's hands. He should really do better.

Aberdeen create a good opportunity as Vicente Besuijen drives forward and whips a great ball in from the right.

Bojan Miovski rises to meet it with his head but gets his effort all wrong.

Ross County have had the better of the opening exchanges as Kilmarnock struggle to settle.

Josh Sims and Yan Dhanda look lively. Both come up from down south with decent CVs - can they replace the Regan Charles-Cook and Joseph Hungbo shaped holes in the County attack?

Kevin van Veen wastes a chance for Motherwell after an attempted clearance lands kindly at his feet.

The Dutchman inexplicably takes the ball to the byeline and then puts it out of play.

And we're off in Perth.

A St Mirren free-kick is cleared to the edge of the box, only for Keanu Baccus to step onto it and hammer a volley back into the box with real power behind it.

It's deflected away by Steven Fletcher, preventing an all but certain goal.

The game at Fir Park is paused momentarily as the players and fans take part in a minute's applause for Faye Taylor, a nine-year-old Motherwell fan who sadly passed away on Wednesday night.

A good flowing move from Livingston opens up the chance out wide for Nicky Devlin, who hammers a shot at Liam Kelly but he can't get the better of the goalkeeper.

Jonah Ayunga threatens for the visitors as he latches onto a cross at close-range but can't direct his header goalward as the ball drifts just wide.

Kazeem Olaigbe blocks the ball out of Sam Walker's hand as the Killie keeper tries to clear. It's a free-kick but no booking.

Those with sharp recollection will remember that Dundee United's Ian Harkes was booked for that same foul in the opening week of the season, before he was then sent off.
