  1. Sow replaces Clark

    St Mirren 1-1 Dundee United (agg 1-1)

    United goalscorer Nicky Clark's afternoon is over as head coach Robbie Neilson sends former Hearts striker Osman Sow up front in his place.

  2. Heading for spot kicks?

    Alasdair Lamont
    Sportsound commentator

    No-one in the ground will be surprised if this goes all the way to penalties

  3. GREAT SAVE!

    St Mirren 1-1 Dundee United (agg 1-1)

    A United corner finds Paul Watson diving at the front post, but goalkeeper Vaclav Hladky dives full length to turn it wide.

    The Czech did well to react as it came through the legs of a team-mate, but it might have been going just wide anyway.

  4. MacKenzie recovered?

    He looks a bit unsteady. The medical staff have got to make sure they make the decision. MacKenzie's got to be careful

  5. St Mirren 1-1 Dundee United (agg 1-1)

    Gary MacKenzie recovers enough to take the free-kick, but that was a worrying moment for the home side considering the former Dundee and MK Dons man has been immense in both legs.

  6. YELLOW CARD Safranko (Dundee Utd)

    St Mirren 1-1 Dundee United (agg 1-1)

    Gary MacKenzie only returned following a head knock in time for the first leg on Thursday and the big centre-half takes another.

    The veteran is left flat on his face after being struck by a swinging elbow from Pavol Safranko.

    Referee John Beaton decides a yellow card will suffice for the Slovak.

  7. St Mirren 1-1 Dundee United (agg 1-1)

    Now it's St Mirren's turn to turn the screw, but neither side has had the quality to fashion a clear-cut opportunity.

  8. St Mirren 1-1 Dundee United (agg 1-1)

    United are piling on the pressure, but St Mirren survive with a few crucial blocks and headers.

  9. Pawlett on for Robson

    St Mirren 1-1 Dundee United (agg 1-1)

    Both sides make changes, with Peter Pawlett coming on for Jamie Robson.

    Robson had a fine game in the first leg, keeping Kyle McAllister quiet, while Pawlett was hauled off at Tannadice.

  10. St Mirren 1-1 Dundee United (agg 1-1)

    Neil McCann
    Former Scotland and Rangers winger on BBC Sportsound

    It's fallen to McAllister at the back post on that lovely left foot of his, so you'd expect him to compose himself and hit the target.

  11. St Mirren 1-1 Dundee United (agg 1-1)

    Great chances missed at both ends.

    First, from that free-kick conceded by Mihai Popescu, his victim, Nicky Clark is found in the clear 10 yards out but makes a mess of his volley.

    St Mirren break clear and Danny Mullen's cross just evades the head of Cody Cooke and Kyle McAllister sclaffs his shot wide.

  12. YELLOW CARD Popescu (St Mirren)

    St Mirren 1-1 Dundee United (agg 1-1)

    John Beaton has been a bit lenient until now, but the referee makes his first booking as St Mirren defender Mihai Popescu clatters into the back of Nicky Clark.

  13. St Mirren 1-1 Dundee United (agg 1-1)

    St Mirren have made a bright start to the second 45, dominating possession.

  14. KICK-OFF

    St Mirren 1-1 Dundee United (agg 1-1)

    St Mirren gets what is a massively important second half under way.

    Still all to play for between the Premiership hosts and visitors looking to replace them in next season's top flight.

  15. Mullen strike calmed Buddies

    Jim Duffy
    BBC Sportsound summariser

    The equaliser calmed St Mirren down and has given them a bit more belief. At 1-1, it can go either way. For United, it's all about the counter-attack, but getting that equaliser makes St Mirren slight favourites

  16. Impressing in Paisley?

    HT: St Mirren 1-1 Dundee United

    It's all square at half-time in Paisley. Who is the shining light for you so far? have your say HERE

  17. Smith to face ex-buddies?

    HT: St Mirren 1-1 Dundee United (agg 1-1)

    Our touchline reporter, Chick Young, is suggesting that there could be a couple of United changes coming.

    Cammy Smith, who joined United from St Mirren, appears to be getting ready to come on.

  18. Too close to call!

  20. Decent spectacle

    HT: St Mirren 1-1 Dundee United (agg 1-1)

    Jim Duffy
    BBC Sportsound summariser

    I think it's been a decent game. There's not been a huge amount of saves. There's been two goals, some great counter-attacking and some errors too. First, with Jack Baird's hand ball for the penalty and then Mark Reynold's sliced clearance for St Mirren's equaliser
