Caretaker manager Gary Rowett is unsure whether Adam Legzdins will resume his loan spell at Burton.
The 25-year-old, who left Albion to join Derby last summer, returned to the Pirelli Stadium on loan last month but made just one appearance before suffering a hip injury.
The goalkeeper has been receiving treatment back at his parent club.
Rowett said: "It is in Derby's hands really. They did us a massive favour in allowing him to come here and he is their player.
"I think he might be doing some light stuff this week, but the hip injury is a difficult one.
"However, Ross Atkins has done brilliantly in the games since he came back in."
