Bury boss Alan Knill will be without Manchester United youngster Nicky Ajose for the trip to Stockport.
The 19-year-old, who is on loan at Gigg Lane until the end of the season, sustained a knee injury in training on Sunday.
He is now set for several weeks on the sidelines but Andy Bishop is fully fit again.
Bishop marked his first start since September with an eighth-minute opener in Tuesday's 3-0 home win over Stevenage and impressed alongside Ryan Lowe.
Knill said: "Nicky is definitely going to miss a few games, but we don't know for how long.
"I am gutted for Nicky because he is a top lad and I thought he was just starting to find some good form again."
