Boucher's farewell day was scheduled for the third day of the Test match against New Zealand at Newlands Park in Cape Town tomorrow. But it will now take place during the Test Series between South Africa and Pakistan next month.
"Mark (Boucher) has made the request following the sudden death last night of former Western Province cricketer John Commins who is the father of his agent, Donne Commins," said CSA acting CEO Jacques Faul.
Boucher added: "Donne has been very close to me for most of my career and has been much more to me than a business partner."
"She has been incredibly supportive over the past few months in particular, during which time she has been a tremendous pillar of support."
Boucher suffered a serious eye injury in a freak accident on the field in England in July last year, effectively forcing his early retirement from the game.
