65' Christie's effort from an Elyounoussi lay-off is deflected behind by Goldson. The resulting set-piece amounts to nothing after Ajer commits a foul.
64' Rangers look uncomfortable with another Celtic corner, but it's eventually cleared away by Helander.
62' Celtic have largely controlled this half, and look more likely to find a winner, but they still need to be wary of the visitors' threat on the break.
60' A fluent, one-touch Rangers move ends with Morelos misplacing a throughball towards Kent.
58' Chance for Elyounoussi! Callum McGregor clips in the perfect cross to find an unmarked Elyounoussi, but the attacker mistimes his jump and he can only plant a weak header narrowly over the bar from six yards!
54' Big save from Allan McGregor! Edouard hits a fizzing half-volley from 25 yards across Allan McGregor and towards the far corner, but the goalkeeper acrobatically gets across to palm it to safety!
52' Balogun's whipped cross from deep skids through Morelos' legs at the back post. If he could have controlled that it would have been a huge chance!
50' Chance for Welsh! Welsh gets to Callum McGregor's corner first and he glances the delivery inches over the bar from eight yards!
48' Elyounoussi managed three shots on target and one key pass in that first half, alongside his goal - Rangers will need to nullify him if they're to leave with three points today.
46' Rangers get the second half underway.
Neither side will be too disappointed with that half, and both can still have realistic hopes of winning this game.
The sides head in level after an open, entertaining first half. Celtic struck first when Edouard set up Elyounoussi for a clever diving header from close range, and they had further chances to add to their lead. Callum McGregor was denied by an instinctive save, while Edouard had a tight penalty appeal turned down. However, Rangers showed plenty of resolve to fight back, and they equalised when Morelos turned Barisic's corner in from close range, to leave the match finely poised.
45' + 1' HALF TIME: Celtic 1-1 Rangers
45' Ajer's weak header is pushed behind for another corner by Allan McGregor.
44' Kent's angled volley from just inside the box is well saved by Bain.
42' So close for Edouard! An intricate Celtic move culminates with Callum McGregor slipping Edouard through on goal and the striker's first-time effort deflects off Allan McGregor and the goalkeeper manages to scramble back towards his line to gather it at the second attempt!
40' Rangers will be delighted with that response! They were under severe pressure after the goal, but they've shown plenty of character to fight back with a set-piece.
35' Laxalt darts inside dangerously before he's finally stopped by Balogun's strong tackle.
33' Turnbull's deft, curling throughball picks out the run of Elyounoussi brilliantly, but the attacker can't quite control it and the chance fades.
31' Big save from Allan McGregor! Callum McGregor holds off Kamara and races into the box at an angle, before firing a low shot towards the near post that the goalkeeper instinctively blocks away with his legs!
29' Celtic look full of confidence all of a sudden and they're pouring forward at every opportunity.
25' Well, that's a morale-boosting moment for Celtic! After a difficult season, they would have been fearing the worst today, but Elyounoussi's header has given them hope of a win!
22' Chance for Morelos! Barisic swings in a wicked delivery from the touchline and it's met by Morelos who can only head a tame effort straight at Bain from eight yards! With better timing, that could have caused Bain real issues!
21' Callum McGregor attempts to hit a diagonal pass over the top to Edouard, but there isn't enough power on it and Helander heads to safety.

11' Rangers have looked sharper so far; they're playing with real urgency and belief in attack - while Celtic look a little more nervous.
