Forfar have been hit with a triple suspension blow following their matches against Dunfermline on Saturday and Rangers on Tuesday night.
The Loons will have defender Stuart Malcolm and top goalscorer Gavin Swankie suspended when Ayr United visit Station Park on Saturday April 26, with midfielder Gary Fusco banned for the last game of the season at Stranraer.
Manager Dick Campbell said: “Making the play-offs is a long shot now and missing these guys makes it even harder.”
