Cavan will host Tyrone in Brewster Park after the GAA abandoned their plans for a double-header in Croke Park following Kildare protests.
The match will take place at 5pm in Enniskillen on Saturday, with ticket details to follow from the GAA, along with clarity for those that purchased them while the game was fixed for Croke Park.
Cavan's Breffni Park is currently unavailable due to the maintenance work, so the Fermanagh venue is their next choice.
Mayo, meanwhile, have moved to reassure fans that they expect all of their season ticket holders will be accommodated for the game in Kildare.
It read: "We note that the Mayo v Kildare Round 3 qualifier has now been for St Conleth’s Park, Newbridge, at 7pm, on Saturday.
"Mayo GAA is awaiting full details from the GAA in relation to tickets for this fixture. We expect that all Mayo GAA season ticket holders will get access to a ticket for this game. There may also be a very limited number of tickets on sale to the general public through SuperValu and Centra outlets.
"In relation to supporters who had purchased tickets for the game in Croke Park on Saturday evening, we are awaiting details from Croke Park, who handle all ticket arrangements for this game.
"The Mayo team and management have this week been preparing to play Kildare on Saturday and look forward to having a passionate Mayo support in Newbridge on Saturday evening."
