The FAI say it may be the only way to complete the February to September season.
The reality of playing League Of Ireland games behind closed doors is impossible for the majority of sides.
Former Portlaoise AFC boss and current Dundalk opposition analyst Shane Keegan says there's little incentive for clubs who aren't receiving money from European competitions to do so.
The FAI are stressing to clubs that matches without fans may be the only way to complete the February to September season.
Keegan says Dundalk and Shamrock Rovers have different priorities to the rest of the two divisions:
