Despite keeping a clean sheet in the FA Cup win over Crewe last weekend, a defensive change is inevitable in order to accommodate Diamond who was suspended for the second-round tie at Gresty Road.
Fellow centre-half Nathan Stanton is also available again after returning to training following the bout of sickness that forced him to miss out against Alex.
Billy Kee may have forced his way back into the starting line-up after a goal and an impressive performance in the Birmingham Senior Cup on Tuesday.
The striker's goal failed to spare Burton defeat against non-league Hednesford Town at Keys Park but his display caught the eye.
Albion boss Gary Rowett said: "I wasn't at the game but (assistant manager) Kevin Summerfield has come back with a very good report about Billy's performance."
Kee had to settle for a place on the bench against Crewe as Rowett opted to play Calvin Zola as a lone striker.
But Rowett is expected to revert to a 4-4-2 formation at home, which could open the door for Kee to return to the side.
