Celtic have announced that the club's chief executive and non-executive directors, plus the first-team players, manager Neil Lennon and the backroom staff have volunteered to take "a significant reduction in salaries".
The Glasgow club says these measures over the period from April-June will help them come through the coronavirus crisis on a stable basis.
Chief executive Peter Lawwell said on the club's website: "I would like to pay tribute to Neil and the players for their desire to play their part and the outcomes achieved.
"I am also grateful to my own executive team for the commitment they have devoted to this outcome in very difficult working circumstances and also their own willingness to play a part in the measures adopted.
"I am extremely appreciative of the willingness of everyone concerned, to recognise the practical difficulties which this awful crisis has created.
"Celtic are in a strong financial position but we are not immune to this unique set of circumstances."
