Terry Devlin’s suspension for his red card handball at Sheffield United guarantees at least one change, as the Northern Ireland man serves a one-game suspension.
There are many other players whose continuing involvement will be under the microscope, after the weak 3-0 loss at Bramall Lane.
Here’s how Pompey writer Jordan Cross think John Mousinho will go, as his side look to avoid falling into the Championship relegation places.

3. RB Jordan Williams
It's certain to be Williams who replaces the suspended Terry Devlin. The only question would be who goes to right-back and who plays left-back. Williams has switched across to reasonable effect in the past, but we're leaning towards right-back for the man from Yorkshire. | Paul Phelan/ProSportsImages
