Aberdeen defender Ash Taylor picks up the first booking of the day as he tugs Stuart Armstrong to the floor after being done like a kipper near the halfway line.

Patrick Roberts has finished the season so strongly for Celtic but the on-loan Manchester City winger has been very quiet today. He wriggles his way through a couple of challenges to find room for a shot but it's a poor effort, dragged wide of the near post.

Quote MessageFine chances for both sides early in this second half. Celtic have some belief back but look fragile at the back. Aberdeen still pressing well.
Celtic 1-1 Aberdeen
Free-kick to Celtic. Leigh Griffiths has a blast and it spins wide. The game is opening up nicely, with both sets of fans in fine voice.

Quote MessageIt all came from Scott Brown's poor pass to McGregor. It's a massive opportunity. No team has created as many chances against Celtic this season.

It's a two-on-two attack as Aberdeen winger Jonny Hayes powers forward on the left. Kenny McLean is screaming for a pass in front of goal but the delivery is just a fraction behind him and a glorious chance is spurned.

Scott Sinclair picks up a Tom Rogic pass and he can see the whites of goalkeeper Joe Lewis' eyes. The Celtic forward tries to go round the keeper but the angle is tight and Lewis is a big unit. Good save.

A let-off for Celtic defender Jozo Simunovic as he elects to leave a cross from Kenny McLean. The ball zips wide of the far post, with Andrew Considine not too far away.

Aberdeen are caught short at the back as a wonderful pass from Scott Sinclair sends Leigh Griffiths racing towards goal. The Celtic striker cuts on to his left foot and his shot takes a deflection off a covering defender as it spins wide of the target.

What about the incident that led to Kieran Tierney going off with a fat lip and bleeding gums?
BBC pundits Steven Thompson and Tom English think Jayden Stockley was a bit naughty, while Pat Bonner and Mark McGhee are giving the Aberdeen striker the benefit of the doubt.

Quote MessageIt’s 1-1 and Aberdeen are right in this game. They go in much the happier team. Aberdeen have put a game-plan in place that shows they are capable of getting the victory. The only question is whether they can do it for 90 minutes. Aberdeen have set the tone in that first half. There is no doubt this is the most uncomfortable Celtic have looked this season.

Quote MessageOn balance of play the happier manager has to be Derek McInnes. His tactics are absolutely perfect. Celtic haven’t been allowed to play and are having to kick it long. It’s been Aberdeen’s first half.

Quote MessageI think it's been a sensational game of football. Aberdeen have turned up and Celtic are being hassled and hurried. They've been drawn into a football war and it is very difficult to call

Quote MessageThe giant new screens at the national stadium read 1-1 at the break but Aberdeen will be the side feeling better about themselves. Celtic have struggled, not by going behind, but by the enforced change in shape due to the Tierney injury. The assurance he gives them at the back and the width and skill going forward has clearly been missing since he went off. Aberdeen will never have a better chance. A very intriguing second half awaits.
Aberdeen deserve great credit for their aggressive pressing and are giving Celtic a torrid time of it.
Brendan Rodgers' side are lacking their usual poise in possession but, despite being under par, they should really be ahead after that injury time miss from Scott Sinclair.
Celtic 1-1 Aberdeen
What a miss!
Aberdeen are pinned back defending their penalty box and Leigh Griffiths again finds plenty of room out on the left. The Celtic striker fizzes in a marvelous low cross and Scott Sinclair runs on to it inside the six yard box only to somehow fire over the top.
