St Mirren sub Duckens Nazon is fortunate not to go into the referee's book for a late challenge on Mark Connolly.

So close for St Mirren.

Duckens Nazon fires in a low cross and, when defender Mark Connolly slices as he tries to clear, goalkeeper Benjamin Siegrist does well to beat it away at the front post.

Will it be a double day of misery for Anton Ferdinand - and Jack Ross.

St Mirren sub Ferdinand's former club, Sunderland, now under the former Buddies boss, have just lost 2-1 to Charlton Athletic in the League One promotion play-off.

It is going to be joy for one of these sides, agony for another, but who will it be?

St Mirren get extra-time under way.

We've had 180 minutes between these two sides and we'll need another 30 before we know which will be playing in the Scottish Premiership next season.

United took the lead through Nicky Clark's penalty midway through the first half, but Danny Mullen fired St Mirren level three minutes later.

It's been tight, it's been nervy, it's been tetchy. And we have more of it to come.

Peter Pawlett has already been booked and the United midfielder throws himself to the ground theatrically - his second blatant dive since coming on as a second-half substitute.

Warrior Gary MacKenzie finally has to give up the fight as the St Mirren defender takes another knock that leaves him groggy.

On comes former West Ham United and Sunderland man Anton Ferdinand into defence.

United sub Peter Pawlett is next in the book for a late challenge on Mihai Popescu.

It is getting a bit tetchy as we prepare for five minutes of stoppage time.

Stephen McGinn is booked for a foul on Peter Pawlett.

The St Mirren captain looks knackered as he hauls himself off the ground to receive the yellow card.

Croat defender Mateo Muzek is next to be pushed on by St Mirren, replacing midfielder Kyle Magennis.

Will the switch be sweet music for St Mirren?

St Mirren boss Oran Kearney makes his first change.

Off comes on-loan Derby County midfielder Kyle McAllister, who has had a disappointing game, and on comes the unpredictable striker, Duckens Nazon, who is on loan from Sint-Truiden.

On-loan Rangers full-back Lee Hodson swings in a superb cross to the back post.

Paul McGinn steams in to meet it with his head, but his downward effort is straight at Benjamin Siegrist and the goalkeeper manages to turn it over the crossbar at the second attempt after first deflecting it high into the Paisley air.

United are caught out by a long ball into their penalty box, but goalkeeper Benjamin Siegrist saves the day with a point-blank block to deny Kyle McAllister.

That's the end of the game for Algerian utility man Rachid Bouhenna.

On comes Calum Butcher, who was sent off in United's Scottish Cup win over St Mirren in February and is just back from injury.

Mark Connolly goes into the referee's book for barging into St Mirren striker Cody Cooke.

Meanwhile, United midfielder Rachid Bouhenna is down injured.
