The costs of the proposed Eircom Park project have rocketed to an estimated £135m.
This is more than double the original forecast.
The FAI's Board of Management have been meeting at CityWest, where a new business plan for the project was being discussed.
Delegate John Delaney of Waterford United, who had briefly left the meeting, again expressed his concern at the project's viability.
"My recommendations are that the FAI have no chance of delivering this project on their own. It's just a non-runner now. The debt is £55-56m, that is the type of borrowing including the land we would have to service. In my view as a Chartered accountant, it's not a runner now."
The Board are due to vote on the future of Eircom Park next Friday.
