Danny East has been left out of Pompey’s trip to Five Lakes as he recovers from his groin problem.
The utility man picked up the complaint last week and missed the 6-1 victory over Bognor as a result.
The injury has failed to resolve itself and it has been decided East will remain at home to receive treatment.
James Dunne (tight hamstring) and Michael Poke (ankle) are also out of tonight’s visit to Thurrock (7.45pm).
They join Wes Fogden (knee) and Tom Craddock (knee) on the sidelines, while David Connolly hasn’t travelled.
Although Jack Whatmough is expected to feature having sat out the Nyewood Lane win with a dead leg.
Andy Awford said: ‘Danny East isn’t here (at Five Lakes) this week, his groin is a little bit worse than we thought so he will stay at home and have treatment with the other physios.
‘There’s no point him being here, we will pick him up Monday and see how he is and whether he is ready for Bournemouth for some minutes.
‘He came in one morning and it felt tight in his groin, it’s just one of those things that you pick up unfortunately, it can happen in football.
‘I was hoping he was only going to be a few days but he needs a bit longer, so it’s a bit disappointing for him.
‘It is part and parcel of the game. He has just got to get back out there when he can.
‘Jack Whatmough trained yesterday, though, and hopefully he will be okay for tonight.
‘But James Dunne has a tight hamstring and has not trained so we may not risk him.’
Poke’s turned ankle keeps him out of tonight’s clash against former Pompey left-back Mark Stimson’s Thurrock.
It means 16-year-old Academy keeper Alex Bass will again serve as back-up to Paul Jones.
Awford added: ‘Michael’s ankle is better but he won’t be available tonight, probably more likely Saturday.
‘So Alex Bass has travelled with us to give us two keepers for Thurrock.’
