Adam Thompson and Conor Clifford come in for Marc Laird and Kevan Hurst
Blues boss Phil Brown made two enforced changes to his side for the trip to Fratton Park to take on Portsmouth.
With Kevan Hurst suspended and Marc Laird suffering from a small injury picked up on Saturday, Conor Clifford and Adam Thompson came in.
Thompson was a straight replacement for Laird in the holding role in midfield.
Clifford’s introduction meant Will Atkinson moved out to the right in place of the suspended Hurst.
Freddy Eastwood and Ryan Leonard were both still missing through injury.
Blues: Bentley; White, Prosser, Kiernan, Coker; Thompson, Clifford, Timlin; Atkinson, Corr, Straker.
Subs: Smith, Reid, Payne, Njie, Woodrow, Laird, Phillips
