Aberdeen aren't out of this one yet, they're still threatening, but United are defending brilliantly.

The thought of European football is maybe spurring the on.

With 85 minutes on the clock, St Mirren are closing in on an incredible win at Celtic Park. But it'll taste sour if it isn't enough to snatch fifth.

They need Aberdeen to score at Tannadice for that to happen.

St Mirren threaten a second on the break.

Dante Polvara tries his luck from range, but Dave Richards makes a good stop to turn it away.

Topi Keskinen, Shayden Morris and Polvara have all come on for Aberdeen.

Jordan Smith has done it again!

The keeper has kept Hibs in this.

This has changed a fair bit this afternoon.

Will we see any more twists?

Another superb save from Hibs keeper Jordan Smith.

Neraysho Kasanwirjo's cross picked out Danilo perfectly, and the Brazilian toed his volley at goal, but Smith got down well.

The corner is then headed straight into the keeper's arms. It's all Rangers at the moment.

James Forrest is turning it on as the veteran Celtic substitute makes it to the bye-line again.

His low cross is scrambled clear this time, but the pressure is mounting on a St Mirren side who will feel deflated if they are hearing what is happening at Tannadice.

James Forrest has made a huge impact already in the few minutes he's been on Celtic's right flank.

He's replaced Nicolas Kuhn and is causing all sorts of bother for a tiring St Mirren defence.

The Buddies support here has gone a little quiet. Perhaps because they know Dundee United are ahead?
