Nicky Clark's own goal separates the sides at McDiarmid Park.

The veteran forward was unfortunate to nick a Blair Spittal corner past his own goalkeeper and the hosts can probably consider themselves unlucky to be behind at the break considering it has been a fairly even opening 45 minutes.

Despite the penalty miss, it was far from the most entertaining first half in Paisley. There were chances for both sides, the best of which falling for Ross County's Jordan White.

Here's hoping for better in the second period.

There's a few heavy challenges going in at the moment and St Johnstone midfielder Sven Sprangler and Hearts centre-half Kye Rowles are the latest to go into the referee's book.

Teetering close to a red card in Perth.

Jordan White should score - or at least make the keeper work - and he knows it.

Kacper Lopata has a great chance to give County the lead but he bundles his effort wide. It looked like he maybe lost his footing as he sent his shot beyond the post.

Moments later, Jordan White rockets his shot over the bar.

Just when I was bigging up the Morton keeper, he concedes a goal! It was a lovely finish from Ethan Ross though, a diving header that had Lewis Budinauckas well beaten. Falkirk well in control here.

Stephen Robinson is putting on a brave face. The St Mirren manager is out at the edge of his technical area, applauding his team's efforts and urging them to keep up the tempo in the wake of that penalty miss. He's hiding his frustration well. Greg Kiltie took it because Mark O'Hara missed his last one. Who's on pens now?

Great chance squandered by St Johnstone.

Graham Carey finds Adama Sidibeh in the clear 18 yards out.

The striker has the chance to go one-on-one with goalkeeper Craig Gordon or find a team-mate but instead shoots hastily low and wide of the front post.

Hearts are well in control here in Perth but there is a nervousness about the visitors defence whenever Benjamin Kimpioka or Adama Sidebeh gain possession around the box.

Intriguing game so far.

The Morton goalkeeper may have conceded a goal in this one, but Lewis Budinauckas has made two brilliant saves to keep the score at 1-0. He's kept out shots from Aidan Nesbit and Calvin Miller, who's snapshot had plenty of power behind it.

Great work from Ross Laidlaw, who saves Greg Kiltie's penalty with his feet. It was straight down the middle. And straightforward for the keeper to block. The stalemate continues.

Hearts threaten again as Alan Forrest's low drive is deflected wide.

Yet another Blair Spittal corner is punched unconvincingly by goalkeeper Ross Sinclair and falls wide of the far post.

Greg Kiltie's effort from 12 yards is save by Ross County goalkeeper Ross Laidlaw.

The first Scottish Premiership goal of the weekend was not spectacular but Hearts will not care after Nicky Clark's own goal put them in front.

Penalty given! Can St Mirren take advantage?

The tussle between St Mirren centre-half Alex Gogic and Ross County striker Jordan White is not for the faint-hearted. At times it's more all-in wrestling than football but it's none the less fascinating. Honours just about even so far in the grappling stakes. Neither goalkeeper has had a save of substance to make in the opening half hour. Oh. Possible VAR check for a St Mirren penalty? Shirt pull? Don Robertson looking at the monitor.

Hearts goalkeeper Craig Gordon saves on the goalline after a corner into the penalty box drops into a body of players from both sides.

Home defender Kyle Cameron shoots on the turn, but the flag is up for some kind of mysterious infringement and it would not have counted anyway.

There's been lots of slack passes from both sides as soon as they get into a good area. So, it has been end to end but not in the way you'd want.

Nearly a carbon copy of Hearts' opener.

This time, Blair Spittal's corner to the front post finds the head of fellow midfielder Yan Dhanda, but this time the flick on flies across the face of goal and wide of the back post.
