The pressure mounts on Celtic manager Neil Lennon as Ross Stewart sends goalkeeper Vasilas Barkas the wrong way from the penalty spot.
Another shock County win over Celtic is on the cards now!

Josh Reid leaves about three Celtic players in his wake as he breaks down the Celtic right.
The full-back's cross to front post finds the home defence hesitant and Christopher Jullien upends Ross Stewart as the striker ghosts in behind him.
Penalty for the visitors!
Celtic 0-0 Ross County

Quote MessageIt's not going well for Celtic so far. They have dominated possession, but this is the kind of game Ross County would have wanted. Celtic still look vulnerable. Kristoffer Ajer looks as if his confidence is shot to pieces

Celtic 0-0 Ross County
County remain a threat on the breakaway and it leads to their first effort on target.
However, Harry Paton's drive from long-range is easy for goalkeeper Vasilas Barkas.
Celtic 0-0 Ross County
Celtic centre-half Christopher Jullien is down with a head knock after clashing with Callum Morris in that corner incident.
The Frenchman recovers and, in the next move, Morris comes off best again in an aerial challenge, only this time team-mate Coll Donaldson is the one on the receiving edge. He will be glad to see his fellow central defender recover too.
Celtic 0-0 Ross County
Tom Rogic fires into the side netting from 14 yards after Callum Morris heads clear from a Celtic corner.
County would have been raging if that had gone in considering it looks like Rogic got the final touch in the move that led to the corner.
Celtic 0-0 Ross County

Quote MessageFrom Celtic's perspective, it's a very slow tempo. They are hoping rather than making it happen

Quote MessageRoss County are doing well, they are looking compact. You expect Celtic's Tom Rogic to be more of a creative force, but they're asking their wing-backs to do that job

Celtic 0-0 Ross County
County midfielder Harry Paton is the first to go into the referee's book for a late challenge on Celtic centre-half Christopher Jullien.
It relieves a bit of pressure as County were knocking on the door again, helped by some nervous moments in the home defence.
Celtic 0-0 Ross County
Celtic are beginning to see more of the ball after that bright County start.
But, with both sides playing with three at the back, the visitors are showing up well considering their recent poor form.
Despite the lion's share of possession, Celtic are looking as vulnerable as you would expect given their recent form.
Celtic 0-0 Ross County

Quote MessageI think Celtic are struggling without a winger-like player like James Forrest or Mikey Johnston. Now you've got to ask the wing backs, can they do it - go beat a player - and that's the question
Celtic 0-0 Ross County
Celtic win a free-kick 20 yards from goal and Odsonne Edouard has his eye on a goal.
The French striker powers a drive through the defensive wall, it's beaten away by goalkeeper Ross Laidlaw and former Oldham Athletic centre-half Alex Iacovitti's knee clears ahead of Scott Brown.

Quote MessageIt's what I've been seeing from Celtic all season. Plenty going forward, look creative, but defensively they are a little bit vulnerable. The question was could 'Ross County get forward' and so far they have. It's a good cup tie
Celtic 0-0 Ross County
An early injury blow for County.
On-loan Birmingham City midfielder Charlie Lakin hobbles off, with his place taken by fellow Englishman Jordan Tillson, who himself had dropped to the bench after taking a knock in his last outing.
Celtic 0-0 Ross County
County are almost ahead out of the blue.
Harry Paton tries his luck from range, but the midfielder's shot is into the side netting.
Celtic 0-0 Ross County
Scott Brown finds Odsonne Edouard deep inside the County penalty box with a precise chip, but the French striker's first touch is poor and defender Coll Donaldson gets a toe in to divert it from a corner.
When the ball comes into the box, Nir Bitton follows up his header with a claim for a penalty, but it was a bit of an ambitious call from the big Israeli.
Celtic 0-0 Ross County

Quote MessageIain Vigurs delayed in possession there for Ross County. He has made some mistakes, he wants to play the game at his pace, but against Celtic you've got to be sharper
Celtic 0-0 Ross County
Celtic break to the other end from that Vasilas Barkas clearance and Diego Laxalt sets up Ryan Christie inside the County penalty box.
The Scotland midfielder makes himself some space, but his low, 16-yard drive is straight at goalkeeper Ross Laidlaw.
End-to-end stuff at Celtic Park so far.
