Nearly an immediate equaliser for Rose as Smart Osadolor's low strike is cleared off the line by Nicky Devlin!

A huge let-off for the hosts.

Hibs force the first save of the game.

Eliezer Mayenda cuts inside and the on-loan Sunderland forward's curling drive is beaten away by goalkeeper Mark Ridgers.

Shayden Morris assists through Reis Peggie's legs, and Bojan Miovski finishes through Paddy Martin's legs.

That's rough on Rose, but it was just a move of quality.

Cove nearly playing themselves into trouble.

Arron Darge is closed down by Marley Watkins who tries to get a snap shot away, but it all happens too quickly for the striker to keep his effort down.

Livingston are living dangerously. Jack McMillan fizzes a low cross into the box and Ayo Obileye's stabbed block somehow isn't diverted in.

The visitors counter through Scott Pittman and Tete Yengi. The Aussie finds Dan MacKay on the right and his deflected shot whistles just wide.

Another problematic corner whipped in from Bonnyrigg's set-piece specialist Lee Currie is hastily cleared.

The visitors from League Two have started the stronger here at Pittodrie.

Angus MacDonald is the first to give Paddy Martin something to do up the other end with a low drive.

Luke Amos has a sight at goal in his first Hibs start after James Carragher fails to clear, but the midfielder flashes his low drive wide.

Now it's Killie who get away with one. Cove really should have opened the scoring there.

Stuart Findlay needlessly heads the ball away as it was soaring into the arms of goalkeeper Will Dennis, which gives former Rugby Park forward Rumarn Burrell the chance to volley home.

Findlay gets himself back to block off the line, but what a start that would have been.

Tell you what, Robbie Horn ought to be a right happy chappy.

As good an opening 10 minutes or so - barring a goal, obviously - as you can dream of against a top-flight club...

Partick Thistle seem to have got away with what looks like a clear handball in the box.

A corner from the right bounced awkwardly and a Thistle defender shepherded it out with his arm. Not given, incredibly.

A poor clearance from Caley Thistle goalkeeper Mark Ridgers puts his defence in trouble.

But the home support utter a sigh of relief as Martin Boyle's snap shot slices wide.

It's end-to-end stuff at Caledonian Stadium, but it's Hibs who win the opening two corners of the game.

But James Carragher is looking commanding at the heart of the home defence playing in front of his dad.

Journeyman striker Smart Osadolor gets a shot on goal for Rose, but his deflected effort from the edge is a simple catch for Aberdeen keeper Ross Doohan.

Huge shouts for a penalty as Matty Kennedy takes a tumble in the box.

Looks like the Killie winger received a push in the back and perhaps a clip of the heel.

Cove might have got away with one there...

An entertaining opening, Livingston into the box with Joel Nouble and then Thistle up the other end with Aidan Fitzpatrick.

Both came to nothing, but a statement of intent from both.

Aberdeen just about manage to clear a Rose corner inside the opening 60 seconds.

Positive start for Robbie Horn's men at Pittodrie and a quick warning for Neil Warnock's Dons.

Around 1,500 fans have made their way north from the capital to support Hibernian in the Highlands.

And they have met by a similar number of home supporters who will be hoping their heroes can cause something of upset and once again reach the last eight of the competition.

A very good crowd in at Pittodrie.

Bonnyrigg Rose are filling that away section - that doesn't happen with Premiership clubs that come up here!

You've got to salute that.

Away we go around the grounds.
