Phillips has missed the last two games with a groin injury but he has returned to training and is in the squad to face Mick McCarthy's side.
Alex McLeish has named the same starting line-up for the last 11 league games and that is again likely to be the case this weekend, with Christian Benitez and Cameron Jerome leading the attack.
Kick-off on Sunday is at 1.30pm.
Blues (from): Hart, Taylor, Doyle, Carr, Ridgewell, Dann, Johnson, Queudrue, Vignal, Bowyer, McFadden, Ferguson, Larsson, Fahey, Gardner, Michel, O'Shea, Jerome, Benitez, Phillips.
