Bangor City will have to wait to find out the date of their away tie at HJK Helsinki in the second qualifying round of the Champions League.
The second leg had been originally scheduled for Wednesday 20 July but could be played 24 hours earlier.
That is if another Finnish side Honka secure a place in the second qualifying round of the Europa League.
They would face Hacken of Sweden in a second leg tie at HJK's Sonera Stadium on Thursday 21 July.
Uefa regulations state that the away side must be allowed to train on the pitch, traditionally the evening before.
Bangor secretary Gwynfor Jones said a change of date for the second leg would not disrupt travel plans for manager Neville Powell and his side.
"I've spoken to Neville," said Jones. "It's him and the players it affects more than anybody.
"Neville's quite happy with it because we had already made arrangements to fly out on the Monday.
"We'll get in there for late Monday evening [and] the players can have a good rest and a light training session before the match on Tuesday evening.
"But hopefully the best thing that could happen is for Honka to be knocked out in the first qualifying round, with all due respect to them, and it won't affect anyone then."
Jones has admitted a change of date for the second leg in Finland could inconvenience some City fans who have already made travel arrangements.
"We do apologise on behalf of the club for that but unfortunately it's out of our hands and [there's] nothing we can do," he said.
