That’s encroaching on barebones territory as the Blues look to make do with the numbers they have amid injury concerns and suspensions.
Youngsters Jay Mingi, Harry Jewitt-White and Liam Vincent have all been called up to help fill gaps in the bench, without seeing any action.
And that’s likely to be the case again on Saturday as Pompey look to stretch their current unbeaten run to six games against John Coleman’s side.
But who exactly is out of the first-team picture, what’s wrong with them and when can we expect to see them back in a Blues shirt?
We’ve delved into the treatment room and, off course, the referee’s bad books to have a look.
5. Jayden Reid - knee
The 20-year-old ruptured a cruciate ligament in the pre-season friendly draw at Luton – just four days after signing a one-year contract with the Blues following an impressive trial. The winger is making steady progress in his recovery and played a part in finishing drills with the group on Thursday. However, there's no urgency to rush him back as the Blues look to give the youngster the best possible chance of recovering fully from the blow. Photo: Nigel Keene
6. Ronan Curtis - Suspended
The Irish man sits out the game against Accrington after picking up a 10th League One yellow card of the season against Fleetwood last weekend. He sat out the midweek win against Oxford, with his ban covering two games, but Curtis likely to return to the side for next Tuesday's trip to Crewe. Photo: Jason Brown
