Manager Mark Robins welcomed back goalkeeper Joe Murphy from a shoulder problem for Tuesday's Johnstone's Paint Trophy victory over Sheffield United as the Sky Blues made the northern section semi-finals.
Striker David McGoldrick and midfielder James Bailey also returned having been ineligible for FA Cup duty last weekend, and all three are again expected to start against the Saddlers.
Robins could well opt to name the starting XI from that which drew 1-1 with the Blades in midweek before triumphing 4-1 on penalties.
"We did well on Tuesday night even though I thought we were lacking slightly in the final third. I still think we need to do better, and we can do better," Robins told the club's official website.
"I don't think we gave them enough problems really and when a team comes here and sets up to defend, we have to do more to break them down and that is what we have to do on Saturday."
