FT: Dundee 1-0 Aberdeen - McCowan nets penalty for deserved opener after MacKenzie penalised for handball following VAR review

Dundee 0-0 Aberdeen
Scott Tiffoney strikes against the post after a Dundee free-kick causes chaos in the Aberdeen box.
Dundee's Antonio Portales appeared to go down in the Aberdeen box in that exchange and VAR is checking...
Dundee 0-0 Aberdeen
Aberdeen make their first change with Junior Hoilett coming off and the enigmatic Duk coming on.
Hibernian have scored six goals in the first 15 minutes of second halves, only Celtic (11) and Hearts (eight) have scored more in the Scottish Premiership this season.
Myziane Maolida
Hibs are level and deservedly so.
Elie Youan slides the ball into Maolida's path and the winger calmly passes the ball into the net.
George Wickens got a touch on it, but couldn't keep it out.
It's a fifth Hibs goal for Maolida. He's been quite the signing.
Ross County 1-0 Hibernian
Adam Le Fondre has the chance to level for Hibs. It's a long ball which he watches bounce in the box and the striker tries to lob County keeper George Wickens.
But it doesn't clear his head.
Dundee 0-0 Aberdeen
Aberdeen more forceful at the start of the second half with Bojan Miovski winning a corner.
Play has to stop, though, after Stefan Gartenmann takes a head knock as he comes into collision with goalkeeper Jon McCracken.
Ross County 1-0 Hibernian
Nick Montgomery has hooked Dylan Levitt at the break and Adam Le Fondre replaces.
Levitt came on at half-time when these two met 11 days ago and changed the game for Hibs.
It's a different story tonight...

Aberdeen have shown more attacking intent in the opening few minutes of the second half than they did in the entirety of the first half.
Ross County 1-0 Hibernian
Having seen a few replays of that Ross County goal, I think David Marshall, Rocky Bushiri and Jordan Obita have to take collective responsibility for a lack of communication.
They all run into each other.
We go again.

Dominant Dundee have had total control of things, the only thing missing is the finishing touch.
On another day they could be a couple of goals ahead.
The big question is will be they rue those missed chances?
The only positive for Aberdeen is the fact they haven't conceded a goal.
Caretaker boss Peter Leven is going to have to change something after a first-half display which has been a far cry from the impressive one they delivered against Kilmarnock at the weekend.
Ross County have a record of W3, D1, L0 when leading at half-time in the league this season.
Hibernian have a record of W0, D2, L7 when trailing at half-time in the league this season.
Ominous for the Hibees?
HT: Ross County 1-0 Hibernian
Josh Sims now has two goals in his last four Premiership games.

Image source, SNSJosh Sims' goal three minutes before the break has struggling County in front.
However, it is another example of Hibs causing their own problems.
After taking a grip on the game and creating a few chances, David Marshall's error in missing Simon Murray's cross allowed Sims to tap in from three yards.
County are half way to a big win.
Image source, SNSDundee have forced the issue but have not so far found a breakthrough against an Aberdeen team bereft of direction.
Scott Tiffoney, Lyall Cameron and Owen Dodgson have all threatened for the hosts and Aberdeen goalkeeper Kelle Roos has had a busy evening so far.
Still all to play for at Dens Park.
Image source, SNSDundee 0-0 Aberdeen
Aaron Donnelly gets to the bye-line and smacks the ball across goal, forcing Kelle Roos to touch out for a corner.
Aberdeen deal with that one but are soon facing another, then a long throw-in from the left.
Still Dundee cannot find a way through. It's desperate stuff at times from Aberdeen.

David Marshall flaps at the ball and Josh Sims has the simplest of tasks.
Dundee 0-0 Aberdeen
The closest Dundee have come.
Lyall Cameron arrives at a bouncing ball, takes a touch and flashes just wide.
Josh Sims
First goal of the night is here and it comes in Dingwall.
It's a nightmare for Hibs keeper David Marshall. Simon Murray whips a cross in, Marshall comes for the ball and misses it and Sims has a tap in.
It's against the run of play, but County are in front!
