The GAA has confirmed that Croke Park will be operating at 50% capacity for the All-Ireland football final.
The sporting body said that processing vaccination passports on a match day for a crowd coming from across the country and abroad would not be possible.
Half of the tickets for the battle between Mayo and Tyrone on September 11 have already been sold.
An additional 1,150 will now be available for the much-anticipated clash.
The confirmation comes after yesterday's Government announcement on the easing of restrictions for sporting events.
A GAA spokesperson said: "The GAA welcomes yesterday’s government announcement regarding the easing of restrictions for sporting events.
"After careful consideration we are confirming that a 50% capacity threshold will apply for the GAA Football All-Ireland final at Croke Park on Saturday week, September 11."
"This means there will be an additional 1,150 tickets for distribution.
"With approximately half of our tickets already distributed and unrealistic logistical challenges around processing Covid passports on a match day for a crowd in excess of 41,150 coming from all over the country and abroad, it was decided to proceed on the basis of a 50% attendance.
"The GAA acknowledges the work of the Department of Sport on this issue and looks forward to the benefit that Tuesday evening’s announcement will have on club games in the weeks and months ahead."
