Chairman James Derry told the official Mansfield Town website on Tuesday "I don't think fans should be focussing on protests against Keith Haslam because he won't be at any more home games and he will be leaving the football club.
"Instead it would be far more productive if everyone got behind the team. We need everyone's support at this time after a disappointing start to the season."
Stags supporters are planning another protest outside Field Mill for the home game with Dagenham & Redbridge this coming weekend.
