Dundalk v Finn Harps, Oriel Park, 5pm [Live on WatchLOI]
It's back to the bread and butter of the league for Dundalk after a golden night at the Aviva Stadium.
Filippo Giovignali's men earned a famous 3-1 victory over Ki Klaksvik in the UEFA Europa League play-off to spark scenes of jubilation.
They can now look forward to winter games against Molde, Arsenal and Rapid Vienna, but they must also negotiate a hectic period that starts with five domestic matches in 15 days.
Second-from-bottom Harps are first up, with clashes against St Pat's, Cork City, Waterford and Derry City before the Lilywhites begin their Europa League group stage campaign.
Dundalk: Dane Massey [hip] is out while Sean Gannon is a doubt due to an ankle injury. Chris Shields is back however after serving his European ban.
Finn Harps: David Webster has served his one-game and is available again. Mark Timlin continues his recovery while Tom McDermott and Ruairi Harkin are doubts.
What they said
Filippo Giovignali (Dubdalk): "Our objective now is Finn Harps on Sunday, because that game is vital for our future. It is, trust me. We can think about Arsenal later."
Ollie Horgan (Finn Harps manager): "In our situation with only five games left to play, every game is vital. Dundalk are a top quality side. They had a huge achievement during the week and will be full of confidence. It's going to be a very tough game."
