The diminutive Irish winger hasn't featured for the Dons since the Europa League draw with Maribor at Pittodrie in July after suffering a hamstring injury.
But, after returning to training this week, last season's player of the year will be included in the squad for the visit of Inverness Caley Thistle.
Boss Derek McInnes told a local newspaper: "Jonny has been training with us for the last few days.
"If the game had been last Saturday I think Jonny would have made it. As it stands we have no issues with Jonny ahead of Saturday’s game."
