On loan keeper Romain Larrieu is staying with the Gills for another two games.
The Frenchman, who first arrived at Priestfield on loan from Plymouth Argyle in January, reached the end of his deal after the Bristol City game on April 9, but it has now been extended until after the game at home to Port Vale on April 21.
Gills boss Ronnie Jepson said: "Plymouth know about our predicament and it's nice of them to help us out, especially as I think they want him to play a few games for them before the end of the season."
Larrieu has kept four clean sheets in 13 appearances so far for the Gills.
