Andy Awford has insisted Alex Wynter will remain part of his squad.
But the loanee’s Pompey presence will be reassessed in January.
The Crystal Palace youngster arrived at Fratton Park on a season-long loan in July after Awford was attracted by his versatility.
Despite predominantly featuring as a central defender at Selhurst Park, Wynter has operated as a right-back with the Blues.
But he has found it tough at times in his 15 matches so far, prompting Awford to last week bring in Matt Fish on loan from Gillingham.
Fish gave a solid debut in the 3-0 win over Morecambe, while Wynter was an unused substitute.
Both Pompey and Palace have the option to end the 21-year-old’s loan early in the January transfer window.
Until that point of consideration arrives, Wynter remains in Awford’s first-team thoughts.
The Blues boss said: ‘Alex is still part of the squad.
‘It’s not a slight or a dig at Alex that I needed to bring in Matt Fish.
‘We will assess it in January.
‘If I want to keep Fish beyond January that might affect the decision on Alex, of course.’
This week’s arrival of Lee Holmes further impacts on Wynter’s presence with Pompey’s loan numbers now up to six.
The winger joins Wynter, Fish, Paul Robinson, Miles Storey and Marcus Bean in the squad.
With a maximum of five allowed in the match-day 18, one of them will miss out completely for Saturday’s trip to Tranmere Rovers.
Meanwhile, right-back contenders Danny East and Adam Webster have now returned to Pompey training following injury lay-offs.
