Vaesen reluctantly agreed to a loan move to the Gills over the Christmas period in an effort to regain match fitness after seven months on the sidelines with a knee ligament injury.
The Belgian keeper plays his final game of that loan spell in the Gills First Division clash with Bradford City at The Priestfield Stadium on saturday providing the game goes ahead - there is a saturday morning inspection at the Kent stadium.
Its doubtful that the loan deal at The Gills will be extended after Nico said earlier this month: "What I have made clear is that once the month is over, that's it. I don't want to be going to another club for a month, then another one."
