Sunday's All Ireland football semi-final clash of Tyrone and Kerry has been deferred.
The GAA's Central Competitions Control Committee (CCCC) confirmed the news on Monday, and has a knock-on effect on the All Ireland final.
The semi-final will now take place on Saturday August 21 at Croke Park.
As a result, the All Ireland Senior Football final will be played on Saturday September 4.
An unspecified number of players were forced to isolate last week after other members of the panel tested positive for COVID-19.
Statement From Tyrone GAA
We would welcome the decision of the CCCC to postpone the fixture V. Kerry for 6 days.
We will continue to comply with all guidelines from the PHA and Croke Park, keeping the health of the players and management as our primary concern— Tyrone GAA (@TyroneGAALive) August 9, 2021
Tiernan McCann, Richie Donnelly, Frank Burns, Rory Brennan and joint-manager Feargal Logan missed the Ulster final win over Monaghan due to a positive case in the camp.
The All Ireland U20 final meeting of Offaly and Roscommon will still be played at Croke Park at 1.30pm on Sunday with the original attendance of 24,000 still permitted.
Tyrone have welcomed the deferral, saying they will continue to comply with all guidelines from Northern Ireland's Public Health Authority and Croke Park.
GAA statement:
The GAA’s CCCC has today confirmed that Sunday’s GAA Football semi-final meeting of Kerry and Tyrone at Croke Park will not take place as originally scheduled and will now be played on Saturday August 21 at the same venue (time to be confirmed).
This decision was taken following a status report received by the GAA relating to positive Covid cases in the Tyrone panel.
This change will necessitate the GAA Football All-Ireland final being re-arranged to take place on Saturday September 4.
The GAA Football U20 final meeting of Offaly and Roscommon will proceed as planned at Croke Park at 1.30pm on Sunday with the same permitted attendance.
The GAA will continue to liaise with the appropriate Government Departments and officials to discuss the practicalities of having these revised fixtures included under the statutory instrument that has facilitated the increased attendances of recent weeks.
The GAA will also be working with the LGFA around the TG4 Ladies All Ireland Junior final scheduled for Croke Park on September 4.
