Andy Considine heads a Niall McGinn corner wide as Aberdeen continue to find it difficult to score a goal.

The architect, not for the first time, is Calvin Ramsay, the 17-year-old debutant winger having earned the set-piece with a cross headed wide by Ryan McGeever.

Aberdeen continue to knock on the door, but Lewis Ferguson's low drive is easy for goalkeeper Sam Ramsbottom after the midfielder bursts into the penalty box.

There were calls for a penalty by Dumbarton as goalkeeper Joe Lewis gave Adam Frizzell a bear hug after the midfielder sent his effort over the bar.

However, BBC One Scotland pundit James McFadden thinks it "was a hopeful one" and thinks the referee got it right as the ball was already heading out of play.

Close call!

It's Aberdeen's turn to squander a sight at goal.

Ross McCrorie lays the ball into the path of Niall McGinn 12 yards out, but the winger is unable to replicate his recent Northern Ireland heroics and blasts it over the crossbar.

The Aberdeen defence is all at sea as Adam Frizzell is able to control a cross on his chest around the penalty spot.

The midfielder toe pokes his follow up into the air under pressure from goalkeeper Joe Lewis, but the effort lands on the roof of the net.

A couple more half chances for the Dons and Ethan Ross' shot is well saved by goalkeeper Sam Ramsbottom.

It is all Aberdeen at the moment and, when Niall McGinn smashes a free-kick against the defensive wall, Florian Kamberi is presented with an ideal chance to open the scoring.

The on-loan St Gallen striker has his back to goal, but with only goalkeeper Sam Ramsbottom to beat, he fires wastefully wide from five yards on the turn.

Caretaker Paul Sheerin told BBC Sportsound just before kick-off that incoming Aberdeen boss Stephen Glass is not having any input into first-team matters until he arrives at the club.

"He's letting us get on with it until he comes in the club. We have had conversations, but he hasn't had any influence on the team," he says.

Aberdeen get the game underway looking to avoid becoming the second top-flight side to exit this season's cup at the first hurdle.

Here come the teams into the sunshine on the banks of the River Clyde - what a perfect scene for a game of football...

Dumbarton manager Jim Duffy tells BBC Sportsound that they have to be careful with their players' fitness ahead of a gruelling schedule.

"We've got another three games next week, so we have to be sensible, but all the players are desperate to play and we've picked a team that we hope are capable of competing with Aberdeen," he says.

"We haven't had great results recently, but today the expectation is for Aberdeen to win the game, probably comfortably. From our point of view, we want to show people that we are a decent side and perhaps better than current results would show.

"It's an absolutely perfect day. We're looking forward to the game."

This is a match-up of two teams in a bit of turmoil.

Dumbarton have won once in six, have dropped to second bottom of League Two and are without a win in three outings.

They've lost two in a row at home, both 1-0, their latest against Airdrieonians.

Aberdeen are fourth in the Premiership, but their form has been even worse, with the managerless side having won once in 10.

They are eight games without a win away from home, losing four.

Indeed, they have lost three in a row 1-0 away from home - the same scoreline as Dumbarton's last three home league defeats - and are without a goal in their last three.

Dumbarton only stepped off the pitch 40 hours ago, losing at home to Airdrieonians, and boss Jim Duffy makes four changes for this game.

Defender Ryan McGeever, midfielders Nat Wedderburn and Adam Frizzell, plus forward Robert Jones, all start, while Ross Forbes, Conner Duthie, Ruaridh Langan and James Wallace drop out.

Aberdeen are still waiting for new manager Stephen Glass to come out of quarantine after his move from Atlanta's second string.

Their interim management team have continued to pick players from the club's academy - and this afternoon is no different.

Defender Calvin Ramsay and midfielder Ethan Ross start, with winger Niall McGinn also into the line-up after his world-class finish for Northern Ireland against the United States last week.

Ash Taylor, Jack Mackenzie, and Connor McLennan drop out.
