Coventry recalled Drysdale on Tuesday, cutting short his intended season-long stay at Priestfield.
Drysdale made 15 appearances for the Gills after joining on loan in October, not long after he had played against them for Coventry in the EFL Cup.
He didn’t manage to pick up any goals or assists, but did contribute to two clean sheets.
The 21-year-old played in both central defence and defensive midfield during his time and ME7, and even featured up front for a few minutes against Swindon Town in December - replacing Vadaine Oliver in the last few minutes and maintaining an aerial threat up top.
Gillingham tweeted: “We would like to thank Declan for his services and we wish him well for the future.”
