A. Halliday gets a second yellow card and is sent off.
90' +5
FULL-TIME: CELTIC 2-1 RANGERS.
Tavernier now crosses powerfully, but Ajer blocks for a corner. You'd think that Tavernier would shoot there!
90' +4
Goldson crosses towards Worrall and he heads the ball back into the danger area, but there's no one on hand to attack the ball and Celtic clear. That could have been Rangers' last chance.
90' +2
A. Halliday gets yellow.
Edouard picks up a loose ball and tries to take it past Halliday, but the Rangers defender fouls him to kill their momentum and give away a free-kick.
Halliday is shown a yellow card for his foul on Edouard.
89'
Referee Madden decides to take no action during a scuffle between Brown and Kent. The Rangers player seemed to push Brown, but Madden keeps his cards in his pockets for now.
88'
S. Davis enters the game and replaces S. Arfield.
Davis comes on for his 23rd Old Firm game, replacing Arfield.
86'
J. Forrest has scored a goal for Celtic! Assist by O. Édouard.
IS THAT THE WINNER?! CELTIC LEAD 2-1! Gerrard will be gutted after such a costly error from Tavernier. McGregor pounces on the loose pass, sends in Edouard who squares to Forrest and the midfielder emphatically finishes with his right foot to put Celtic ahead late on.
Edouard had been brilliant today and he adds an assist with a great squared pass to Forrest.
85'
Every ball is being hotly contested and neither side are really able to grab control of this game at the moment. It seems as though there's another goal to be scored in the final few minutes, but who will score it?
83'
J. Defoe enters the game and replaces Candeias.
Gerrard makes his second change of the game in quick succession as Candeias comes off for Defoe. Could he be the one to steal a winner?
82'
Candeias, now, tries to find a team-mate in the box and his cross falls to Halliday. Toljan stands off him and gives him space for a shot, but it takes a deflection for a corner.

80'
S. Brown gets yellow.
Brown is shown a yellow card after catching Arfield with a high boot.
79'
G. Kamara enters the game and replaces R. Jack.
Jack, who had a chance to put Rangers ahead, comes off for Kamara, who's receiving his first taste of Old Firm action.
77'
Goldson is able to continue and he comes back onto the pitch to take his place in defence.
73'
J. Toljan enters the game and replaces K. Tierney.
There's far more belief about this Rangers performance now. They've got a little momentum, they're retaining the ball well and challenging for every loose ball. Is there going to be a winner?
It's game over for Tierney as Toljan, usually a right-back, comes on to replace him.
70'
Rangers are looking to complete their comeback and Arfield sends a cross across the box, but there's no one there to attack it for them.
66'
Gerrard is desperate to keep Kent permanently, but his parent club, Liverpool, are demanding a large fee to make the deal happen, which is proving to be a stumbling block. With a goal of that quality, it's easy to understand why!
64'
T. Rogić enters the game and replaces O. Ntcham.
Ntcham comes off for Rogic as a response to giving away the lead.
63'
R. Kent has scored a goal for Rangers! Assist by J. Tavernier.
KENT EQUALISES! IT'S 1-1! Tavernier finds Kent with a magnificent pass, he gets himself away from Boyata and dribbles into the box and he powers his right-footed shot under Bain. That's brilliant fighting spirit to score from their first attempt on goal!
Tavernier's pass was absolutely excellent to find his team-mate. Kent had a lot to do himself, but Tavernier set him up brilliantly.
60'
Lustig finds Forrest in the box with a good cross, and the midfielder gets the ball under control, but his shot takes a deflection to earn a corner. Boyata heads the resulting set piece over the bar.
58'
Tavernier has space to break into on the right and he passes inside to Jack, but his first touch is heavy and he gives away a foul while trying to reclaim the ball off Ajer.
55'
Celtic are eager to score a second and Lustig is next to have a go with a right-footed shot from outside the box aimed at the far corner. It's a good strike, but it's off-target.
52'
McGregor fires a low cross into the box, but there are no Celtic takers as the ball rolls through a promising area.
51'
Tierney nearly creates an opening for a shot with a touch to cut inside following a very neat passage of play from Celtic, but his touch was heavy and the ball goes out for a corner.
49'
Was there a foul? The referee says no as Sinclair and Tavernier tangle with each other in the Celtic box.
48'
Tierney clears and Celtic launch a counter-attack, but Sinclair is flagged for offside out on their left.
47'
Rangers fans will be encouraged with this start as Halliday wins a corner early on, their first of the game.
46'
S. Sinclair enters the game and replaces J. Hayes.
Sinclair, who's scored four times in Old Firm derbies, comes on for Hayes.
Action resumes at Celtic Park. Here's hoping the second half is just as thrilling as the first!
45' +3
HALF-TIME: CELTIC 1-0 RANGERS.
45' +2
Hayes tries to beat Tavernier out on Celtic's left flank, but the Rangers defender gets his body in the way to win a goal-kick and end a promising period of possession for the hosts.
45'
Referee Madden gives McCrorie a stern warning after colliding late with Boyata. The Celtic defender goes flying through the air, but no card is shown. This game is extremely heated!
43'
S. Arfield gets yellow.
Rangers win a free-kick from Lustig's foul and this seems to be the only way they're going to be able to get the ball off of their opponents.
Arfield is shown a yellow card after dragging McGregor back as the Celtic winger countered. Hayes was overlapping on his left and, perhaps, the foul prevented another goal.
42'
Celtic are in complete control of proceedings. They've not given Rangers a sniff of a chance on goal and it's proving to be a keep-ball exercise as they try to exploit their numerical superiority.
40'
Celtic win a throw in Rangers' half and they recycle possession backwards, going in search of a second goal.
38'
Celtic are looking very comfortable against the 10 men of Rangers and Tierney is the latest to test McGregor with a shot headed towards the far post. The goalkeeper gets a hand to it, though.
35'
Rangers are now a man and a goal down and they've struggled to create any noteworthy chances so far in the first half. Gerrard has some real problems in this game and you can't see the score staying at 1-0. The Gers have a mountain to climb.
31'
A. Morelos goes off after a red card!
MORELOS IS OFF! Bobby Madden has shown the Rangers striker a straight red card! The players are crowding him, but he's having none of it as the referee consults his assistant. Morelos seemed to throw out his left arm to catch Brown in the face in an off-the-ball scuffle.
30'
Hayes has picked up a slight knock after taking Candeias' foot to the face. He's up and about once more, though.
28'
O. Édouard gets yellow.
Edouard is shown a yellow card for his celebration. He won't mind, though!
27'
O. Édouard has scored a goal for Celtic! Assist by J. Forrest.
Forrest did well to get his head up and spot Edouard's run and he played a perfect pass to send him in behind the defence.
WHAT A GOAL! CELTIC LEAD 1-0! There were numbers forward, but Edouard decides to go at it alone and he uses his quick feet and skill to send Worrall every which way before shifting the ball onto his left foot and firing a rocket past McGregor.
26'
J. Hayes gets yellow.
Tierney wins a free-kick as Morelas holds him back. McGregor passes it short into Hayes and he wins another free-kick after a collision.
Hayes is shown the first of, perhaps, many yellow cards for a late tackle. The Celtic fans are singing his name.
22'
Celtic have played well so far, particularly while trying to exploit Tavernier and Halliday at fullback. It seems as though attacking the flanks and sending crosses into Edouard is the plan.
20'
Edouard does fantastically well, using fast feet to beat two Rangers defenders and he sends McGregor in on the left side of the pitch, but his cross was poor and nothing comes from it.
18'
Tierney tries to find Edouard with a long, testing ball over the top of defence, but Goldson defends well and puts it out for a throw.
17'
McGregor makes another save, though Ntcham hit his shot straight into the Rangers goalkeeper's path. The Celtic midfielder had time to pick his spot in the goal and he should have done better with the chance.
15'
Tavernier fires in a cross from a deep position on the Rangers right, but Lustig heads the ball away and Celtic are now in possession.
14'
After an exciting opening 10 minutes, in which Edouard had a brilliant chance to put Celtic ahead, the game has settled down somewhat with the two sides exchanging brief spells of possession.
10'
Edouard wins a free-kick with some excellent hold-up play, using his body to shield the ball from Rangers' defenders and draw a foul. Goldson clears, though, and Celtic don't capitalise.
8'
Halliday eventually takes the free-kick after Ajer's face is patched up, but Worrall can't make proper contact with the ball as Celtic win a goal-kick. Ajer is able to return, too.
4'
Edouard again tests McGregor with a shot from distance and Celtic win a corner out of the defensive confusion resulting from the save.
2'
Rangers have started brightly, enjoying a spell of possession inside Celtic's defensive third, but it comes to an end as Morelos is flagged for offside.
1'
Referee Bobby Madden blows his whistle and gets the action underway at Celtic Park.
Hello and welcome to live coverage of the third Old Firm derby of the season.
CELTIC XI (4-2-3-1): Scott Bain; Mikael Lustig, Dedryck Boyata, Kristoffer Ajer, Kieran Tierney; Olivier Ntcham, Scott Brown, Callum McGregor; James Forrest, Odsonne Edouard, Jonny Hayes.
SUBS: Jeremy Toljan, Jozo Simunovic, Scott Sinclair, Tom Rogic, Dorus de Vries, Oliver Burke, Timothy Weah.
Celtic are 10 points clear of Rangers at the top of the Scottish Premiership and a win against their rivals would all but secure an eighth successive title, putting Neil Lennon in a strong position to take over the reins permanently.
RANGERS XI (4-5-1): Allan McGregor; James Tavernier, Joe Worrall, Connor Goldson, Andy Halliday; Daniel Candeias, Scott Arfield, Ryan Jack, Ross McCrorie, Ryan Kent; Alfredo Morelos.
SUBS: Jermain Defoe, Steven Davis, Wes Foderingham, Jon Flanagan, Glen Kamara, Nikola Katic, Lassana Coulibaly.
The teams are on their way out and we’re moments away from kick-off.
That's all from Celtic's 2-1 victory over Rangers. Thank you and goodbye!
Now 13 points ahead of their Old Firm rivals, Celtic have essentially tied up the Premiership title given there are only seven games left to play and Lennon is in with a chance of securing the job permanently. It's heartbreak for Gerrard, but his side didn't deserve to win as Rangers fail to win back-to-back games against their rivals.
