Gareth Evans returns to skipper the Pompey team against Coventry at Fratton Park this evening.
The midfielder replaces Andy Cannon in one of three changes from the side narrowly beaten by Sunderland on Saturday.
Sean Raggett makes his first start since signing on loan from Norwich earlier in the summer, with Christian Burgess dropping to the bench.
And Ross McCrorie – who impressed after coming off the bench at the Stadium of Light – comes in for Anton Walkes at right-back.
Pompey: MacGillivray; McCrorie, Downing, Raggett, Brown; Evans (c), Naylor, Close; Harness, Marquis, Curtis
Subs: Bass, Bolton, Burgess, Haunstrup, Cannon, Pitman, Harrison
