Kenny Jackett has insisted Dion Donohue’s recent injury record won’t scupper his chances of winning a new Pompey contract.
Donohue limped out of last week’s 2-2 draw against Burton with a hamstring injury, ruling him out for up to four weeks.
The Welsh talent has made just four appearances this season.
He previously suffered from separate groin and hamstring problems, as well as glandular fever and foot blisters during pre-season.
Donohue impressed during his spell in the Blues’ starting XI but is again confined to the treatment table.
His current deal runs out in June, after arriving from Chesterfield for an undisclosed fee in August 2017.
Pompey do, however, hold the option of extending the former Everton youth player’s deal for a further 12 months.
Donohue’s return to first-team action has been earmarked for the start of December.
Jackett stressed there will be ample time left in the season for the 25-year-old to clinch a new contract.
The Blues boss said: ‘He was pretty much injury free last season.
‘If you’re looking at those situations, it would be the nature of the injuries.
‘But they’re not injuries that should recur or potentially go again, really.
‘I don’t think it will have a big effect. He might be out for the majority of November.
Hopefully he can get back and be fit and ready by December.
‘He still has 60 per cent of the season by the time he comes back.
‘In terms of the injuries, it won’t inhibit it (a new contract) – he’s at a good age as well.
‘It’s hard to put your finger on it (current injury problems). It’s frustrating but at the moment I can’t put a reason on it.’
