Mykola Kuharevich is back to lead the Hibs line after missing the past seven games through injury.

Kieron Bowie is also part of the home squad, taking a place on the bench for the first time since he picked up a hamstring problem with Scotland U21's back in September.

St Johnstone are aiming to reach the last 16 for the first time since lifting the trophy in 2021 and this might be a nice distraction from league duty.

Saints have fallen nine points adrift at the bottom of the Premiership with no wins in nine outings, seven of them losses, and manager Simo Valakari will be busy trying to reshape his squad this month.

Motherwell are on a run of just one victory in seven, but Stuart Kettlewell's side have won 2-1 home and away against the Perth side already this season and have not lost in five visits to McDiarmid Park.

Alexander Jensen, Aberdeen's latest signing from Brommapojkarna, makes his first start having come on as a substitute in the 3-0 defeat by Rangers.

He joins fellow defender Kristers Tobers, who has been starting since his arrival from Grasshopper Zurich, while on-loan Tottenham Hotspur centre-half Alfie Donnington will hope for a second appearance from the bench, where Preston North End forward Jeppe Okkels joins him after starting at Ibrox.

After disposing of Girvan, Keith and Buckie Thistle, this is a fabulous outcome for Clydebank. The financial rewards will be a huge boost but it's the memories made in these type of fixtures that can be priceless.

And the near 2,500 visiting fans will ensure they enjoy their trip to the capital. They travel to Easter Road with few expectations and in the knowledge that all the pressure is on Hibernian.

It's been a miserable few months for Aberdeen, who have gone 12 games without a victory.

The Dons team bus makes a rare turn north today to Borough Briggs, with Elgin City having lost just once at home in League 2 this season.

With Aberdeen in freefall, there would be a complete meltdown if they don't do the business this afternoon and nervous fans will be haunted by recent memories of that night in Darvel...

This might not jump out as one of the most eye-catching ties, but both teams will see this as a great opportunity to land one of those money-spinning glamour games in the next round.

Cove are going reasonably well in League 1, where they are fifth and very much in the title mix.

It is a very different story for Forfar, who are rock bottom in League 2, where their SPFL status really does appear to be on the line.

We’ve heard of the new manager bounce but what about the new owners' bounce? Dunfermline will find out if such a thing exists. The Pars have been bought over by US analytics firm Park Bench, with the deal being confirmed today, just 24 hours after they confirmed the arrival of Michael Tidser as head coach. Quite the incentive for the players you'd think.

Although the Pars are facing Stenhousemuir from a division below, there’s only two places separating them, with Dunfermline are a place off the foot of the Championship, while Stenny are sitting second in League One just two points off top spot. We could have a close one on our hands.

Clydebank have knocked Hibs out of the Scottish Cup before but that was back in February 1987 when both sides were in the top flight.

The club disappeared in 2002 after a period of administration, with a new team quickly starting over on the lowest rung of the Scottish junior football ladder.

Now they are in the sixth tier and looking good for another promotion and taking an incredible 2,450 fans to Easter Road.

St Johnstone: the only team in the SPFL with a 100 per cent record in Scottish Cup finals. Played two, won two. Never mind a final, though - they'd be happy just to win a game at the moment. They've not managed that since 23 November when they beat Kilmarnock here. What chance the Cup gives them some joy?

Motherwell come here with an injury crisis but otherwise in fine fettle. Fifth in the Premiership, three wins and three draws from their last nine and perhaps more importantly: two wins over their hosts already this season.
