A decision is expected on Thursday on whether Saturday’s Danske Bank Premiership clash between Linfield and Crusaders will proceed at Windsor Park.
It is believed the crunch top-of-the-table showdown will be postponed due to ongoing safety fears at the stadium.
The West Stand – also known as the Kop – was sealed off on Tuesday over concerns of possible subsidence after cracks were discovered in the structure.
A structural report is due to be released on Thursday morning.
The NI Football League is then expected to announce a decision over whether Saturday’s game can proceed.
If postponed, it will be played at a later date with a neutral venue likely to be used if Windsor is deemed unfit to host the fixture.
Linfield have two home games remaining this season – Saturday’s meeting with Crusaders and the visit of Glenavon on April 11.
The Crues – who are nine points clear of the Blues with only five games left – could effectively clinch the Gibson Cup with victory at the international stadium.
But with that fixture now expected to be postponed, any potential title celebrations will have to be put on hold.
Other key fixtures include the Irish Cup final between Glentoran and Portadown on May 2, and Northern Ireland’s Euro 2016 qualifier with Romania on June 13.
Ulster Rugby’s Kingspan Stadium has been mooted as a potential venue for both.
