Substitute Louis Longridge superbly sets up Ali Crawford with a chip to the back post, but the midfielder volleys his effort wide from 12 yards.

Danny Redmond has been struggling with a bit of cramp in the Accies midfield and is replaced with Greg Docherty.

Darian McKinnon has a sight at the United goal after a cut-back from Rakish Bingham, but the midfielder lashes the ball well over from 18 yards.

On-loan Norwich goalkeeper Remi Matthews makes a superb save at full stretch to touch a looping Mark Durnan header over the crossbar.

However, it would not have counted anyway as the United defender was pulled up for a foul on his marker.

Dougie Imrie is so close to a goalscoring touch as he can only reach a cross to the back post with his studs and his effort slips wide of United's far post.

Accies manager Mark Canning makes his move, taking off tiring winger David Templeton and bringing on Louis Longridge.

Charlie Telfer almost makes an instant impact, laying the ball into the path of Mark Durnan.

But, while the big defender's drive from 15 yards has plenty of power, it flies just over the Accies crossbar.

Accies winger Dougie Imrie goes into the referee's book for wiping out Thomas Mikkelson.

The United striker is lucky to walk away uninjured and Imrie fortunate not to receive a red card.

United already look more dangerous after that change and Thomas Mikkelson gets his head to a corner looped to the back of the penalty box and on-loan Norwich City goalkeeper Remi Matthews does superbly to turn it wide at the front post.

United boss Ray McKinnon quickly takes the right decision by taking off Wato Kuate and replacing him with Charlie Telfer.

Kuate shows his anger toward a couple of team-mates as he troops off.

After that David Templeton shot, Sean Dillon has a go verbally with Wato Kuate and the midfielder aims a swipe at his team-mate.

The two square up before the corner is cleared.

David Templeton wriggles around the edge of the United penalty box and the winger's low drive takes a deflection just wide of the far post.

United burst forward as Simon Murray wins the ball, but the striker elects to shoot instead of playing in Blair Spittal and his effort is deflected wide.

Accies goalkeeper Remi Matthews is lucky to get away with a poor clearance in front of his own goal.

It deflects off Thomas Mikkelson, but it hit the striker's hand and a foul is given.

A clever free-kick from Ali Crawford, who chips it over the home defence, where Massimo Donati is lurking.

But the midfielder just fails to get back onside in time.

There are no changes at half-time, despite the urgings of our BBC Radio Scotland pundits.

United get the game underway.

We are a third of the way through this two-leg Premiership play-off final and it remains on a knife-edge.

Fellow pundit Allan Preston agrees with Derek Ferguson about Wato Kuate.

The 21-year-old midfielder from Cameroon was a youth at Manchester City before joining Akhisar Belediyespor in the Turkish top-flight and Asteras Tripoli in the Greek Superleague.

However, he looks like a player who was then loaned out to the Greek third tier with Trikala.

Preston puts it more colourfully than me.

"When I saw him before, I looked at his CV and he's played for some good clubs, but he's looked like a fan who has won a competition to get a game," he says.
