Captain Cole Skuse (knee) striker Sam Baldock (calf) and the experienced Louis Carey all came through training unscathed after recent injuries and look set to be available to help the Robins battle for npower Championship survival.
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.
Striker Ryan Taylor is two weeks away from a return to training, meaning the former Rotherham forward could be available before the end of the campaign but Richard Foster has an Achilles problem which will be assessed by the club's medical staff.
City's 5-3 victory over Barnsley last weekend has moved them within three points of safety ahead of the clash with Paul Ince's men.
