Windsor Park has carried out a deep clean after a Linfield player tested positive for the coronavirus.
The stadium will be closed until tomorrow while the work goes ahead.
The chairman of Linfield FC said the club's priority is to look after the welfare of players and staff after the player tested positive. Roy McGivern said the news was "very unpleasant" and said issues around football will be addressed in due course.
In a statement, the club said it was "taking advice from the relevant authorities and will provide an update when we have further details".
It comes after a Linfield player went into self-isolation after coming into contact with a fellow player with the coronavirus.
He will be absent for a fortnight after coming into contact with the Hanover FC player.
He informed Linfield, who have excused him from training.
