Bryn Morris makes his Pompey debut in tonight’s top-of-the-table clash at Luton.
He starts in the centre of midfield in one of two changes from the side that drew with QPR in the FA Cup on Saturday.
Jamal Lowe also comes straight back into the starting 11 after returning from suspension.
Dion Donohue and Louis Dennis are the duo to make way, with both of them dropping to the bench, where they are joined by new loan signing Omar Bogle.
Pompey: MacGillivray; Walkes, Whatmough, Clarke, Brown; Morris, Naylor; Lowe, Evans, Curtis; Pitman (c)
Subs: Bass, Burgess, Haunstrup, May, Donohue, Dennis, Bogle
