Next Sunday’s All-Ireland senior football semi-final between Kerry and Tyrone could be delayed by a week.
The Tyrone squad is understood to be dealing with a Covid-19 outbreak.
An update on their situation is expected today.
Joint-manager Fergal Logan and a number of players were unable to attend their Ulster final win over Monaghan recently.
In a statement released on Saturday, Tyrone GAA said “It was decided to have all panellists and management tested for the virus at the weekend.”
