Dion Donohue’s return to match action has been earmaked for next week.
The Welsh talent is set to feature for Pompey’s reserves in their Premier League Cup tie at Plymouth on Tuesday.
Donohue has overcome his groin injury which has ruled him out of the Blues’ past five matches.
The former Chesterfield man is back in full training but is not available for Saturday’s visit of the Pilgrims in League One.
And while he also won’t be involved in Pompey’s Checkatrade Trophy clash against Gillingham on Tuesday, he will play for the reserves on the same night.
Manager Kenny Jackett said: 'We have no fresh injury concerns.
'Donohue was the latest one with his groin but he's over that and is training.
'I think he'll play in the Premier League Cup on Tuesday, which is coincidentally away at Plymouth as well.
'That will be his first game.’
Nathan Thompson is also back from his knee problem he picked up in the curtain-raiser victory over Luton.
The right-back marked his return for the reserves in a 3-1 friendly victory against Swindon behind-closed-doors on Tuesday.
Thompson came through that game unscathed and is available for Derek Adams’ side’s trip to Fratton Park.
Jackett added: 'Thompson has no problems and I'm looking forward to three home games with all but one available.'
