With MacKinnon seeing Ridgers as first-choice goalkeeper it looks like Knight – who is under contract until next summer – may soon be headed elsewhere.
MacKinnon said: “Mark has come in and he’s going to be number one and Stuart is at a stage now where he wants to enjoy his last couple of years playing football.
“He’s made his wishes clear and I have to respect that. I like Stuart and I’ve got a lot of time for him.
“He’s a really good goalkeeper who can still do a job for someone so his request has been granted and we’ll see who comes in for him.”
