Van der Sar, who has been in record-breaking form for Manchester United in the Premier league this season, decided after Euro 2008 that he no longer wanted to play for his country.
The 38-year-old accepted an emergency call-up for last year's World Cup qualifiers against Iceland and Norway but has now turned down a second request.
Van Marwijk admits he only considered Van der Sar because he desperately wanted to find a solution to his current problems.
Maarten Stekelenburg has been dropped by Ajax, while Henk Timmer has been told he can leave Feyenoord after a poor season.
The inexperienced Michel Vorm of FC Utrecht is Van Marwijk's third option ahead of the upcoming qualifiers with Scotland and Macedonia.
PotentialVan Marwijk told The Herald: "Against my better judgment I called Edwin because of our present difficulties.
"We had agreed the book was closed before we had these injuries and while I knew what the answer would be, I still called him.
"All our other keepers have a story to tell, sickness, injury or poor form but I will stick by Stekelenburg.
"He has the most potential of all of them and is the best available.
"He is not playing for Ajax, and that is a disadvantage, but this gives him a chance to prove that he can come back stronger."
