A home tie against lower league opposition is the type of respite Ange Postecoglou will be grateful for after a difficult week.
Celtic threw away a 2-0 lead in Seville to lose 4-3 against Real Betis in their Europa League opener but fans still had plenty of positives to take – which is more than can be said for the shock loss at Livingston three days later.
But now it's a chance to get back on track after the boss lost four of his last five games.
He's told fans this little blip shall pass and reaching a Hampden semi-final would go some way to blowing away the clouds.
It looks like one man will be available to lighten the load on a stretched squad. Captain Callum McGregor remains out but a debut for new striker Giorgos Giakoumakis seems likely, though it's unclear if he'll start.
There's another choice to be made at left-back after Boli Bolingoli flopped on his return to the squad.
Would a cup tie in which the Hoops are overwhelming favourites not be ideal conditions to hand Liam Scales a debut at Parkhead after being named on the bench at the weekend?
Kyogo Furuhashi was spotted in the background of snaps from Lennoxtown but he's still a few weeks away while Chris Jullien and James Forrest should return to training after next month's international break.
Greg Taylor, too, could be out until November after his shoulder surgery but Mikey Johnston featured against Livi last weekend.
