2. Harvey Blair - Out
After returning to the fray before the international break, the winger was the only change to the match-day squad on Saturday against Leicester. Mousinho revealed the 22-year-old missed the game due to a hamstring issue, which kept him out of the first seven games of the season.

4. Callum Lang - Out
This fixture last season was arguably one of Pompey’s and Lang’s highest moments of the season, with the forward netting all four in their 4-1 triumph over the Sky Blues. The 26-year-old continues to be absent but is progressing well in his recovery from hamstring surgery at the start of the season. Photo: Dan Istitene
