Ferguson curls it but it's punched clear by Scott Bain. Then Sam Cosgrove tees up Stevie May who somehow heads it wide. Big, big, chance for Aberdeen.

Scott Brown fouls Sam Cosgrove on the edge of the Celtic box. Aberdeen with a great chance from the free-kick now....

Timothy Weah is inches from sneaking on to the end of a superb Kieran Tierney cross.

Then Mikey Johnston totally embarasses Dominic Ball and whips the ball across goal, but there's not any Celtic takers. Neil Lennon has his head in his hands, agony for the Celtic boss.

Aberdeen forward Greg Stewart drags a shot wide when he should have played in Sam Cosgrove. It's end-to-end at the moment, but the quality has been suspect.

John Souttar slides in to challenge Jesse Curran in the Hearts box. Curran looks up expectantly but referee Nick Walsh says it was a fair tackle.

St Johnstone are starting to knock on the door but Livingston are dealing with the threat well so far. Gary Holt's side will be just one point behind The Saints if it stay like this.

Sam Cosgrove fizzes a delicious ball across the Celtic goal, but it's hooked clear by Jeremy Toljan.

That's Timothy Weah now on for Celtic, in place of Oliver Burke.

It's a big final 15 minutes at Celtic Park in the context of the title race. If Celtic score, they'll go 10 points clear and over the hill and far away. But if Aberdeen score, well, that changes things.

Motherwell are unlucky not to make it four. Elliot Frear gets to the edge of the box, his pass towards Curtis Main looked more like an attempt to curl the ball into the far corner, but it reached Main who didn't know too much about it.

It bounces off the big striker's chest with the goal gaping and goes wide. Then Gboly Ariyibi blasts over from the edge of the six-yard box.

It's Celtic's turn to threaten now. Mikey Johnston floats a cross to the back post for Oliver Burke, but it's just out of reach. Nir Bitton then latches on to the loose ball and sees his shot blocked.

Motherwell have lacked the same punch they had in the first 45 minutes, but they break well and had Gboly Ariyibi's first touch been better he was in space on the left. But the Hamilton defence are able to get in and clear before he can get the shot away.

A good period for Aberdeen. They've won their first corners and the roar from the away end is growing louder.

Can they break the deadlock?

The second half has not really sparked into life as yet at Dens Park.

Dundee are toiling, there's an anxiety about their play every time they advance while Hearts seem content to sit on their lead and look for the counter attack.

Hamilton's best chance of the game as Tony Andreu lobs the ball towards the top corner, but it's wide. He's shaking his head, feeling he had little support from his team-mates.

That is lovely from Celtic's Odsonne Edouard. He waltzes into the Aberdeen box and gets a shot away which Joe Lewis saves. It's scrambled for a corner and then Aberdeen get a free-kick for a foul by Kieran Tierney.
