Crucially for Danny Cowley, he will have Owen Dale and Dane Scarlett back in his disposal after the pair were both unavailable for last week’s win over MK Dons in the FA Cup.
The pair were denied the chance to feature by their parent clubs but are both expected to make an instant return following their absence.
The head coach delivered positive news on the injury front with Louis Thompson, Tom Lowery and Michael Jacobs all back in training.
Cowley admitted he will have to make a tight call on the latter but ruled out the central midfield duo for the contrast at Adams Park.
Joe Morrell declined the chance to have the weekend off after his return from the World Cup and could also make an instant return to the squad.
Here’s how we believe the Blues could line-up in front of the Sky Sports cameras on Sunday.
5. LB: Connor Ogilvie
The left-back was dropped from the side against MK Dons as Cowley opted to use Denver Hume at left-wing back. With the ex-Sunderland man fully fit, he’ll be pushing Ogilvie harder than ever for a place in the starting line-up. Photo: Jason Brown
6. RW: Owen Dale
The 24-year-old missed last week’s victory after Blackpool denied him permission to play with a January recall possible. Nonetheless, he’s playing for the Blues now and will make an instant return to the starting line-up against Wycombe. Photo: Simon Roe
7. CM: Marlon Pack
Injury free and back into the Pompey line-up. The midfielder has been an ever-present in the Blues’ side when fit and it’s not a surprise to see him in the middle of the park again on Sunday. Photo: Jason Brown
8. CM: Jay Mingi
Like Swanson, the 22-year-old just keeps getting better and better the more he’s on the pitch. Mingi put in a man-of-the-match performance against MK Dons last week and, with the return of Pack, was given freedom to venture further forward. Although Morrell is back, the youngster is likely to feature in the centre of the park once again. Photo: Jason Brown
