Lee Brown is fit enough to return to the Pompey starting line-up this afternoon.
He has recovered from a hamstring injury to replace Dion Donohue in one of three changes from the side beaten by Blackpool last week.
Andy Cannon is handed his first start following a January arrival from Rochdale, while David Wheeler also starts.
Andre Green comes out following his recall by Aston Villa, while Brett Pitman drops to the bench, where he is joined by new signing Bryn Morris.
