Quote MessageMcLennan has been hugely impressive since he came on at half-time. The 19-year old has really taken the game by the scruff of the neck. Aberdeen are turning the screw now, the chances are flowing. Livingston are struggling to keep things together.

Gary Holt makes his final substitution, sending on Jack Hamilton for Dolly Menga, who has put in his usual tireless shift and played a crucial part in Livingston's second goal.
Aberdeen 2-2 v Livingston
All action now.
Lovely bit of skill from Stevie May on the edge of the area but the striker's lack of confidence is evident as, faced with Liam Kelly one on one, his snap-shot is too close to the Livi keeper who nonetheless makes a terrific save.
Aberdeen 2-2 v Livingston
Big call from referee Craig Thomson. It looks like a penalty after Sam Cosgrove goes down in the box under a challenge from Scott Robinson, but the Aberdeen striker is booked for diving instead.
Would like to see that one again...
Aberdeen 2-2 v Livingston
Andy Considine will not remember this game fondly, After his defensive howler in the first half, the centre-back has a free header from a few yards out from Stevie May's cross, but can only steer his header wide of the left-hand post.

Quote MessageMcLennan produces the cross. McLennan's been brilliant since he came on. That change has worked a treat. Burns doesn't know how to handle him. He's (McLennan) gone by him again. He drove it across the face and big Sam Cosgrove gets a little touch and it goes high into the roof of the net - a well worked goal
Aberdeen 2-2 v Livingston
Livingston boss Gary Holt wastes no time in taking action, bringing off Bobby Burns and Keaghan Jacobs, and sending on Steven Lawless and Scott Robinson.

Conor McLennan has been a lively presence since he came on for the second half and another run and cut-back from the byline gives Niall McGinn a decent sight of goal, but his right-footer can only find Liam Kelly's mid-riff.
Promising signs for the Dons though...

Quote MessageI've been saying all season that Aberdeen are OK at the back but I'm beginning to have my doubts. They look very nervous. Obviously Michael Devlin's not available to them. Andrew Considine I would expect to do better. It's a worrying recipe, when you're struggling to score goals but look solid defensively and then that defence starts falling apart and starts leaking goals

Aberdeen 1-2 v Livingston
Max Lowe whips in a cross from the left flank, but Sam Cosgrove volleys high and wide with his left foot.
Aberdeen 1-2 v Livingston
Lewis Ferguson is appealing for a penalty after Keaghan Jacobs gives him a tug on the shirt, but referee Craig Thomson gives free-kick the other way.
The Dons win another corner, but Niall McGinn's inswinger is an easy one for Joe Lewis to collect.
Aberdeen 1-2 v Livingston
Early chance for Dons. Connor McLennan stabs a cross in, Stevie May diverts it into the path of Sam Cosgrove, whose effort is deflected wide of the far post.
Aberdeen 1-2 v Livingston
Can Aberdeen find a swift response in this second half? Derek McInnes has sent on 19-year-old Connor McLennan for Scott Wright.

Quote MessageWhether it be a back three or a back four, Livingston do what they do. They are difficult to beat, well organised and work really hard for each other. Gary Holt will be over the moon.

Aberdeen v Livingston (19:45 GMT)
Just to confirm what's at stake for both sides here.
Aberdeen could move back into the top six with a win.
But if it stays like this, Livingston will leapfrog St Johnstone and move up to fifth place on goal difference.
