The 200 people allowed into League of Ireland games when the season resumes must include players, coaches, medical and security staff and media.
It means there will be little or no wriggle room for any fans to attend the matches until at least August 10, when phase four of reopening the country kicks into play.
Then, up to 500 people will be allowed and that will open the door for a small number of spectators at games.
Clubs were informed of the 200 person decision in written communication from the FAI late last night.
They were also reminded that players are banned from taking showers after matches until told otherwise.
In April, a 40-page document had outlined how a maximum of 214 people would be allowed to attend a behind-closed-doors game.
Those figures included a total of 42 players, 20 technical staff, five match officials, 20 ball boys or girls and their supervisors, 10 stewards and two Gardai, but more outside.
Also included were up to 28 broadcast staff including commentators and cameramen, 12 journalists, eight photographers and eight cleaning staff.
