Ayr can call on new recruit Andy Graham against Dumbarton
Ayr's Andy Graham will make his debut against Forfar at Station Park after the centre-half joined from Dumbarton.
But the Honest Men are missing the suspended Ross Docherty and Alan Trouten, who is suffering from a slight groin problem.
Manager Ian McCall said: "We had a long trip to Ross County in midweek and despite losing 2-0 we put on a good performance. However, I will freshen the side up and having Andy in our ranks now allows more scope to do that.
"Forfar are a strong side but they had a tough game against Hearts in midweek so they do not have any advantage in that sense."
Kevin Nicoll is suspended for Forfar after his straight dismissal on Tuesday.
Danny Denholm, who was also dismissed, is free to play as his suspension for collecting two yellow cards will be served in the knock-out competition instead.
Andrew Black has been added on loan from Dundee, while the Station Park men are missing Mark Baxter (ankle), Thomas O'Brien (hamstring) and Gavin Swankie (hamstring).
Manager Dick Campbell said: "There is no point in complaining about players that are not available as it is part and parcel of football. We will just get on with things and look to defeat an Ayr side that have begun the season well."
