Pompey signed off from the Championship with defeat at Nottingham Forest.
Dexter Blackstock was the difference with both second-half goals to give his side a 2-0 win at the City Ground.
But this wasn’t about the result for the 2,300 travelling Pompey fans at the game.
With many in fancy dress, the away fans had a party as they waved goodbye to the English game’s second tier.
And all players and staff gave them an emotional ovation at the full-time whistle, with shirts being thrown into the stand.
There was little action on the pitch in the first-half - with Chris Gunter blazing over the only real chance.
Forest made the breakthrough with 20 minutes left as Blackstock turned in Garath McLeary’s cross.
Jamie Ashdown made two world-class stops to deny Blackstock, before the striker’s header squirmed through Ashdown’s hands from a corner late on to settle it.
Now it’s all about the fight for the club’s survival off the pitch for Pompey - and, hopefully, a future in League One next season.
