Callum Johnson and Cam Pring will make their Pompey debuts in this evening's EFL Trophy contest with Colchester.
The full-back duo replace James Bolton and Lee Brown, as Kenny Jackett makes four changes from the side that beat Stevenage on penalties in the Carabao Cup 10 days ago.
Craig MacGillivray comes in for the injured Alex Bass, between the sticks, while Paul Downing makes way for Jack Whatmough in the centre of defence.
Subs: Turnbull, Bolton, Brown, Close, Cannon, Williams, Harrison
