From what we can find out, it wouldn’t be affected by his involvement in tonight’s match against NSI Runavik.
Neil Lennon will want to name as strong a team as possible as they bid for qualification to the group stages.
They’ve already lost Dylan McGeouch permanently this summer while Scott Allan returned to parent club Celtic and it’s not certain he’ll return before the start of the season.
So McGinn must play as one of their few midfield options.
But Celtic fans need not worry that their potential signing would be Cup-tied in Europe if he was to play tonight and then join them later this summer.
UEFA regulations state that “a player may not play in a UEFA club competition for more than one club in the course of the same season”, but those rules do not apply to the qualifying stages.
Therefore, McGinn would be clear to get involved for Celtic in Europe this season.
With two bids having reportedly been rejected so far, you’d expect the Hoops to return with a third bid sometime soon and that could be enough to make McGinn their man.
