Asked if he could provide any information on the club’s stance, Levein said: “No.”
St Mirren sold MacPherson to St Johnstone in January 2022 after a spell on loan to the Perth club.
He has made 65 appearances since arriving at McDiarmid Park and started all five of their games this season.
Asked whether MacPherson would be in the squad for Sunday’s visit to Kilmarnock, Levein added: “I’m not commenting on the situation. I don’t want to talk about it.
“Apologies, but that’s my approach this morning. I don’t want to get into it.”
