League One clubs have today (June 9) voted to curtail the season, meaning that Pompey finish fifth in on an unweighted points per game system.
It means that Kenny Jackett’s side will now face Oxford in a two-legged play-off, with the winners facing either Wycombe or Fleetwood for a spot in the Championship.
Chief executive Mark Catlin said: “There is a slight feeling of disappointment because we were committed to finishing the season on the pitch.
"We’ve got a shot of getting to the Championship and the lads are pumped up, so we have to grasp the opportunity with both hands."
“But the vote has happened and that’s done and dusted now, so we look forward to an exciting play-off against Oxford.
“We’ve got a shot of getting to the Championship and the lads are pumped up, so we have to grasp the opportunity with both hands.
“Now we’ve got some clarity and the things we’ve been discussing internally – and with the Tony Goodall Fans’ Conference – about refunds for tickets can be finalised. We’re confident of getting this information out to supporters by the end of the week.”
The dates for the play-offs – which will take place behind closed doors and be screened on Sky Sports – will be announced in due course.
