Defender Louis Carey, midfielder Cole Skuse and striker Sam Baldock are poised to return from injury.
Carey and Skuse has been out with knee problems and Baldock has had a calf complaint.
Skuse has been absent since the end of January while Carey took a blow to his knee in the 2-0 defeat at Blackburn on February 2.
Baldock had been close to a return at the beginning of this month but suffered a minor setback, causing him to sit out City's last four games.
Head coach Sean O'Driscoll told the club's official website: "They're all recovering well and should be able to train properly with the rest of the squad this week."
