Pompey are in the middle of a concerning run of form, which has seen them win just one of their previous 11 Championship matches.
This has seen them slump to 20th in the standings heading into the latest international break of the campaign, with Millwall up next.
The Blues have been without a number of key personnel at various stages of the season, which has no doubt played a significant role in their worrying start.
But there is light at the end of the tunnel on the injury front for John Mousinho, with the cavalry set to return over the coming weeks.
We’ve taken a look at the latest situation of all of Pompey’s current injured cohort - and when they could be back from the sidelines.

2. Callum Lang
The forward has been a huge miss in Pompey’s attack, having been out since August with a hamstring injury, which required surgery. The 27-year-old should complete his long-awaited return for Millwall’s visit next week. | Alun Roberts/ProSportsImages
3. Thomas Waddingham
Waddingham was on track to return against the Lions later this month after missing more than two months of action due to a quad issue sustained in training. Mousinho has since revealed the striker will now remain absent for another 6-8 weeks. Should that timeframe stay correct, a return in mid-to-late December could be expected for the Aussie talent. | Simon Roe/ProSportsImages
4. Franco Umeh
Pompey fans are still yet to capture a glimpse of the £500,000 deadline-day signing as he remains sidelined with an ongoing hamstring injury. Mousinho is hopeful the winger would have returned to full training by the Millwall game next week as they look to build him up to speed. | Portsmouth FC
