Right down the middle. Don Cowie will be furious. It's been an even game but as we approach half-time, County find themselves behind.

Akil Wright, what were you thinking?!
The County centre-half practically punches the ball out of the sky as Livingston float a free-kick in.
Bizarre.

The home team remain in complete control of the tie, but no clear-cut chances have came their way in the last 15 minutes. Clydebank will be thrilled to make it to half-time just one goal down.

Queen of the South 0-2 St Mirren
St Mirren are enjoying themselves at Palmerston, and well they might with a two-goal cushion.

Elgin City 0-1 Aberdeen
So close to a second for the visitors - and for Shayden Morris.

BBC Scotland at Easter Road
Despite being under the cosh and a goal down, every time Clydebank come forward their fans are giving them huge vocal backing. They still believe they can get back into this game.

The Dons survive those early chances to take the lead.
It comes moments after Peter Ambrose's close-range header is turned over superbly by Aiden Glavin.
However, the on-loan Kilmarnock goalkeeper is helpless as Shayden Morris sweeps home from around the penalty spot.
