Seán Boylan has called on the GAA to facilitate Tyrone and push their All-Ireland semi-final with Kerry back a further week.
A Covid-19 breakout in the camp saw Croke Park move the game back six days this week to give the Red Hand players the opportunity to recover. However Tyrone GAA, while thanking the association for the initial postponement, have said that they might be forced to concede the fixture without a further move of the game.
A spokesperson for their county board said that there were disappointed that they were not being provided with "sufficient time to prepare a proper challenge for Kerry."
Kerry GAA accepted the decision but acknowledged the difficulty it created for their travelling support who had "made plans to travel to Croke Park for Sunday's game."
Boylan, who contracted Covid himself last year, told RTÉ's The Championship Podcast that the Ulster champions won't be able to perform to their best if the game goes ahead on Saturday week.
"It was the most frightening thing that ever happened to me in my life," said the four-time All-Ireland-winning manager.
"I'd be an old man compared to these lads, but when you get somebody that gets Covid properly it nearly destroys the natural vitality of youth - it wrecks them.
"Everybody thinks that they can go out in three or four days and play again - it's absolutely nonsensical.
"Because they're good athletes I could see them recovering in 10 days but I couldn't see them recovering in four or five days - not a hope in hell.
"I would have seen it with one of the Meath lads who got it last year, and how it affected him. When you go to Croke Park and you don't perform there's no point in saying, 'sure I had Covid'.
"I know there's an argument that the club championships have to start but there's no reason why they couldn't start in the other 30 counties.
"I'd rather be safe than sorry. I know if it was the lads that I was involved with down through the years and you were faced with it, yes you would go out [and play]. But you'd like to think that everybody would have a fair crack of the whip.
"I've no vested interest in the blessed world here. I just want to see lads being able to do what they set out to do."
Looking ahead to the other semi-final - Dublin versus Mayo - which is set to go ahead tomorrow evening at 6pm, Boylan was reticent to pick a winner.
In his time as Meath manager he had many great battles against Dublin, and his 1996 All-Ireland-winning team showed that it was possible to turn things around against the Blues. The Royals had lost the previous year's Leinster final by 10 points, but dethroned their city neighbours before going on to lift Sam Maguire.
Indeed, it was Mayo who Meath beat in the final - a pair of games perhaps seen as the Green and Red's best opportunity to end their All-Ireland famine which now stretches to 70 years.
"It's a great opportunity for Dublin to find their mojo again," said Boylan.
"Mayo are probably the most extraordinary team of all time - they're like the resurrection the way they come back.
"It has the makings of a cracker. Something I learned in sport a long time ago is that when it comes down to a two-horse race there is no such thing as a favourite.
"A lot of the lads playing for Mayo now have never experienced an All-Ireland semi-final, which is brilliant. They're brilliant - they're well capable of winning. But Dublin are also well capable of finding their form again.
"The man in charge [James Horan] will only be happy if Mayo win, because that's what he will consider rebuilding."
