Tyrone are planning a fresh appeal to have their All Ireland senior football semi-final pushed back another week.
Their game with Kerry has been deferred until Saturday week, due to a COVID-19 outbreak in the Red Hand camp.
But joint manager Brian Dooher says just over 50% of their panel are currently able to train.
He told the BBC they may struggle to field a team next week.
"Based on our experience of Covid to date, and known that to get players integrated back into the panel having recovered from Covid-19, is a fairly significant timeline.
"All the medical evidence points towards that and anything we have seen to date definitely reinforces that.
"We believe that we will struggle still to field a team on Saturday week, the way the situation stands at the minute.
