The Scottish Football Association has confirmed it had drafted contingency plans to bring in match officials from outside the country amid a planned strike by referees in Scotland.
SFA chief executive Stewart Regan expressed his support for under-fire referees and vowed to continue dialogue with their representatives to avert this weekend's action.
But he added: "While we remain hopeful that the situation can be resolved to everyone's satisfaction, we have no option but to draw up contingency plans, which will involve sourcing match officials in other countries."
The Scottish Senior Referees Association has informed the governing body of its intention to refuse appointments this weekend after a unanimous vote at their monthly meeting on Sunday.
Referees acted amid fears one of their number would come under physical attack after a number reported being threatened at home, in the street and the workplace.
Regan said: "I have every sympathy for the refereeing fraternity at this time and completely understand why incessant scrutiny, criticism and questioning of their integrity has brought them to the brink of a withdrawal of labour.
"I cannot, however, condone what will amount to strike action and believe we must now engage in positive dialogue to avert the possibility that we will have no football this weekend.
"This scenario is not helpful to the image or reputation of the game. Fulfilling the weekend fixture calendar is our priority and we have an obligation to the leagues, supporters, clubs, sponsors and media partners to do our utmost to ensure all senior games are refereed."
On Tuesday night, the Scottish Football Association revealed they had held "constructive" talks with Scottish match officials to try and avoid a strike, but negotiations will continue on Wednesday.
A spokesman for grade one match officials said: "After a constructive three-hour meeting with the SFA, talks are due to continue tomorrow. But the situation is that the weekend position is unaltered at present."
