Schumacher, the Shakers' top scorer this season with 10 goals, will miss the rest of the campaign having played through the pain of a hernia problem for a number of months.
The former Everton youngster has finally admitted defeat to his condition and is expected to undergo surgery next week.
Veteran defender Efe Sodje is expected to be fit having had treatment on a jaw injury he sustained when a ball struck him in the face during the 2-0 defeat to Leyton Orient.
Valery Mezague came on for Sodje midway through the second half but may have to be content with a place on the bench once more.
Boss Kevin Blackwell has winger Craig Jones (hamstring/thigh), Phil Picken (knee), Adam Lockwood (groin) and Shane Byrne (blood infection) as long-term absentees.
