Ross County 0-1 Inverness CT
Carl Tremarco is spectacularly denied by Scott Fox. The Caley Thistle defender strides forward on to the ball and pops an effort from 30 yards. It squiggles its way towards goal but Fox is equal to it as his flying legs manage to block.

County have started the second half on the front foot, but will they step up?
Quote MessageCounty have let themselves down as some of the build up play has been good. I don't think there's anything in the game, both have had their moments. Predominantly Caley Thistle on the break. County for me were beginning to take control of the game and Caley Thistle scored and they fell out of the game but they've fought their way back into it. The moment of class and quality though came from Doran.

Quote MessageIt's fast-paced, pretty feisty, but there's a lack of quality. When you look at the chances County have had in front of goal, that composure, that final part of the jigsaw has just been missing. But the one little bit of quality and class we've witnessed has come from Doran.

Quote MessageIt was a fantastic strike. That’s the sort of area you want to get Aaron Doran into. It was a great first touch that set him up for the shot.

Michael Gardyne has been expressing himself a little too colourfully to referee John Beaton.
Quote MessageHis autobiography could probably be called "conversations with referees" as he's had a few in his time.
Pretty entertaining fare in Dingwall, play swooping from end to end with numerous chances for either side.
Inverness are ahead - and are decent value for their lead - thanks to a cracking drive from Aaron Doran.
Michael Gardyne, though, has been a great menace to the Caley Thistle backline but has been unable to convert three very good opportunities.
Tom Walsh drew two excellent saves from Scott Fox at the other end as Inverness finished the half strongly.
Not much in it at the break...

Ross County 0-1 Inverness CT
Brad McKay is the latest Caley Thistle player to work his way into the County box.
The defender's square-ball is blocked behind for a corner which the hosts clear.
That's the last act of the half - no injury time required.

Quote MessageInverness have put some quality balls in the box. Another good chance gone a-begging.
Ross County 0-1 Inverness CT
That's another big chance for the visitors, who are delivering a very impressive showing.
Carl Tremarco escapes up the left, and his floated cross is met on the volley by Walsh.
He strikes it into the ground, but he ball bounces over with the aid of a deflection and the corner comes to nothing.

Quote MessageIt was a good five-minute spell for County but they've settled down. They need to get possession and get it to out to Gardyne and see what he does.

Scott Fox has to be on his toes to prevent Inverness going two up.
Tom Walsh was sprinting on to a through-ball but the County stopper was sharp and brave enough to smother the ball at his feet.

Former Hibernian youth Sean Welsh was the first player to have his name taken by referee John Beaton about 10 minutes ago.
He's just caught Kenny van der Weg late too. He won't get away with many more of those...

Quote MessageI thought that was the second. That wasn't about power, more placement and certainly had Fox scrambling. Just shows you don't need to take the leather off the ball. Little bit of thought, little bit of culture. But a magnificent save.

Quote MessageIt’s a lovely strike from Walsh. Fox is keeping Ross County in this Cup tie.
Ross County 0-1 Inverness CT
This game has come alive in the last few minutes.
After Gardyne's near misses, Inverness power downfield and Tom Walsh forces a brilliant save from Scott Fox.
Walsh's curling reversed effort from the edge of the box is parried clear by the County stopper at full stretch.
