Just one change for Hibernian this evening and it's a fairly obvious one with Christian Doidge - now free from suspension - going straight into the starting line-up as Alex Gogic drops to the bench.

Ross County have Josh Reid and Ross Draper suspended after both were sent off on Saturday and Callum Morris also drops out.

Coll Donaldson and Carl Tremarco come into the back four and Jordan Tillson gets a spot in midfield.

Hibernian: Barnes, P McGinn, Porteous, Hanlon, Doig, Wright, Hallberg, Newell, Boyle, Doidge, Nisbet.

Substitutes: Samson, Gray, McGregor, Stevenson, S McGinn, Gogic, Bradley, Gullan.

Ross County: Laidlaw, Watson, Kelly, Donaldson, Iacovitti, Tremarco, Paton, Tillson, Vigurs, Hylton, Shaw.

Substitutes: Randall, Gardyne, Mckay, Lakin, Wright, Williamson, Doohan.

Time for a quick choc-ice, sausage roll or well-earned cup of tea. Celtic and Rangers both record victories; St Johnstone and Hamilton settle for a point apiece in Perth.

We've got Hibernian v Ross County (18:00) and Motherwell v Kilmarnock (18:15) still to come.

So no drifting off on the couch! We need you alert for our remaining games...

This was a comfortable and assured Celtic performance that delivered three crucial points and another clean sheet. Essential ahead of their next fixture away to league leaders Rangers, who show little sign of offering any cheap route to narrowing the gap.

Celtic's margin of victory could have been more emphatic. However, there were one or two moments that United might have exploited in a slightly improved second half show from them. Micky Mellon’s side got a little better but didn’t do enough.

Some big decisions lie ahead for Neil Lennon. Presumably he retains Vasilas Barkas in goal; the keeper had little to do overall today. Does captain Scott Brown return to bring vital experience? If so, at who's expense?

The stakes are high for Celtic and supporters will demand their winning run continues.

Rangers head into Sunday's Old Firm derby in good heart after what turned out to be a fairly routine win over St Mirren.

There was to be no repeat of the Ibrox side's League Cup defeat in Paisley a fortnight ago, although they had to survive an early scare as Jonathan Obika scooped over.

Goals from Kemar Roofe and Alfredo Morelos before half-time were enough to ensure Steven Gerrard's side entertain Celtic with a 16-point advantage over the reigning champions.

After an even first half, Callum Davidson will be wondering how his side haven't come away with all three points after a dominant second half which saw the hosts squander a number of a clear-cut opportunities.

Brian Rice will be proud of his backline who defended resolutely for the most part.

What a big point that could be for his side come May.

Celtic earn a comfortable win with long-range strikes from Ismaila Soro and David Turnbull in the first half and a lovely lob from Odsonne Edourd after the break.

But it comes at a cost with defender Chrisopher Jullien forced off injured three days before facing Rangers at Ibrox.

He's got to score! No?!

The ball falls into the path of Michael O'Halloran in the Accies box, but he fails to direct his close-range effort on target.

Are we destined for a goalless draw in festive Perth?

Diego Laxalt's driven cross presents Jeremie Frimpong with an open goal six yards out, but the Celtic full-back somehow diverts the ball back towards the 18-yard line.

The linesman's belated offside flag spares the full-back's blushes.

Again the hosts squander a heading opportunity as Chris Kane fails to divert a free header on target from a Danny McNamara cross.

Straight after David Wotherspoon sees a header of his own go into the near-post side netting.

Ianis Hagi is played behind the St Mirren defence from Alfredo Morelos, but the Romanian midfielder's flashing cross has no takers in front of goal.

St Mirren, though, are not finished in this game and are camped around and inside the visiting penalty box.

That killer third goal was an example of tremendous interplay between two strikers topped off by a sublime Odsonne Edouard finish to finally settle this match.

The through ball from strike partner Leigh Griffiths was superb allowing Edouard to muscle in behind the back line and dink the ball perfectly over Benjamin Siegrist.

The visitors have improved in this second half with Celtic looking a little more fragile at the back on occasion but Neil Lennon’s side entirely deserve the points and are heading for another clean sheet on top.

A crucial result ahead of the upcoming trip to Ibrox.

Accies see a rare sight of goal in this second half as Andy Winter takes aim but, like almost every shot in this game so far, it's from long range and sails over.

Celtic and Rangers are both coasting to victories against Dundee United and St Mirren, respectively.

It remains goalless in Perth between St Johstone and Hamilton Accies. Shall we see a goal at McDiarmid Park or is destined to end 0-0?

Kemar Roofe is close to extending Rangers' lead with a volley from an acute angle. The striker might just have been trying to play the ball back into the danger area and prevent it going for a goal kick, but a St Mirren head had to come to the rescue on the line.

That's the striker's last involvement as he is replaced with winger Ryan Kent.

There's no doubt St Johnstone have been the better side this second half, but their dominance hasn't resulted in any clear-cut openings so far as Danny McNamara sees a tame left-footed effort gathered easily by Kyle Gourlay.

Joe Shaughnessy receives a yellow card for a foul on Joe Aribo. As things stand, Rangers will maintain their 16-point lead at the top of the Premiership, having played three games more than title rivals Celtic.

Another chance for Celtic as Leigh Griffiths' free-kick hits the wall and falls to Odsonne Edouard in the box, but the French striker can't find a way past keeper Benjamin Siegrist.

A nervous moment for 400th Rangers appearance man Allan McGregor as he tries to allow a through ball to enter his penalty box, but winger Dylan Connolly's toe intervenes before the goalkeeper can reach down to collect. However, the midfielder sends the ball behind for a goal kick.
