Josh Thompson will tonight be given his Pompey debut.
Michael Appleton has revealed the central defender will face Bournemouth in the Johnstone’s Paint Trophy following his arrival from Celtic.
The former triallist negotiated his release from the Scottish giants by mutually agreeing for the final year of his contract to be cancelled.
That paved the way for him to join Pompey as a free agent on Friday in an initial one-month deal.
The paperwork was not completed in time for the 21-year-old to face Oldham.
However, he is set to be named alongside Kevin Long in the centre of defence tonight.
Appleton said: ‘Josh will be ready and fine to play tonight.
‘He has been great in pre-season for us and was gutted he had to go back up to Celtic.
‘But things have changed and if you have got a player who is prepared to rip his contract up at such a club like Celtic to come and play for Portsmouth, that says everything about him as a character.
‘Josh has shown a bit of faith in the football club and myself and I won’t forget that.
‘He’s a big lad and a big presence and I think will do okay for us.
‘He has still a lot to learn and is only young.
‘But he is desperate to get better and better and will want to learn every day in training.’
Thompson spent time on loan at both Peterborough and Chesterfield last season.
