Recent recruit Andre Green is named on the bench as Kenny Jackett keeps faith with his in-form line-up this afternoon.
The Blues boss announced the same starting XI for a fourth-successive match after ending August in third spot.
That means winger Green, a loan signing from Aston Villa on Wednesday, takes his place among the substitutes against Plymouth.
However, deadline day recruit Joe Mason did not sign in time to be eligible for today’s match.
The only alterations are to Pompey’s bench, with Nathan Thompson and Green coming in.
They replace Louis Dennis and Brandon Haunstrup.
Meanwhile, former Pompey loanee Stuart O’Keefe is in Plymouth’s starting line-up.
Pompey: MacGillivray, Walkes, Whatmough, Clarke, Brown, Naylor, Close, Lowe, Evans, Curtis, Hawkins.
Subs: McGee, Burgess, Pitman, Thompson, Wheeler, Close, Green.
