Gillingham club captain Barry Fuller and top scorer Simeon Jackson are probably only going to be fit enough to start one of the two Easter games.
Defender Josh Gowling is set to travel with the squad following a hamstring injury, but Simon King (ankle) is unlikely to play again this season.
Gillingham boss Mark Stimson told BBC Radio Kent: "Every game is crucial now. There are three points at the game on Saturday against Oldham and that's what we'll be looking for.
"We have to try and maintain the form we're in.
"I wouldn't know who the other sides around us have to play, I just know that there are some big teams and some big games and that's why we want to stay in this league.
"This is the business end of the season and we're in good form. It's nice to have some bodies and some options."
