Pompey and Fleetwood will meet for just the third time this weekend.
And the Cod Army are attempting to maintain their 100 per cent record, having won both previous fixtures.
They took place in League Two during the 2013/14 campaign, with Sonny Bradley’s own-goal separating the sides at Fratton Park.
Town were promoted via the play-offs at the end of that season and have since finished 10th, 19th and 4th in the third tier.
They missed out on a top two spot by just four points last term and were then narrowly beaten over two legs by Bradford in the play-offs.
A 3-2 victory over Bury earlier in the week leaves Fleetwood seventh in the embryonic table, with a game in hand over most other teams.
But Uwe Rosler’s troops were beaten 3-1 at Bristol Rovers in their most recent match away from Highbury Stadium.
They are five points above Pompey in the standings and the Fratton faithful will hope to close that gap on Saturday.
Oliver Hawkins could be back after missing the last game with a head injury, but Milan Lalkovic (Achilles) and Jack Whatmough (knee) are both out.
Conor McAleny is back in training for the visitors following an ankle problem, while Bobby Grant has been put on a ‘specialised programme’ as he seeks a recall.
