Pompey produced their most convincing display of the season to ease past Cheltenham at the weekend.
But they will likely face a sterner test when high-flying Bolton make the trip down to the south coast this evening (7.45pm kick-off).
The visitors sit fourth in the table and have won seven of their past eight games to move to within six points of the automatic promotion places.
And a 2-0 victory at 10-man Accrington six nights ago means they are heading off to Wembley for April’s Papa Johns Trophy final.
Perhaps the excitement generated by that was behind their slow start against Port Vale on home soil at the weekend.
They fell behind to Ellis Harrison’s strike, only for goals from Victor Adeboyejo and Josh Sheehan to ensure the points remained in the north-west.
Pompey visited Wanderers twice in the space of just four days last month – and suffered defeats in both the Papa Johns Trophy and the league.
But that was just before John Mousinho took charge and form has improved since, with 10 points collected from the last 12 available at Fratton Park.
And the Blues emerged 1-0 winners when the sides met on the south coast during the 2021/22 campaign, with John Marquis netting the only goal early in the second half.
This evening’s game likely comes too soon for Tom Lowery (hamstring) and Reeco Hackett (back), while Jay Mingi (knee), Clark Robertson (hip) and Zak Swanson (groin) are building towards being available for selection again.
But Marlon Pack (knee) and Jayden Reid (knee) are now the only two players still in the treatment room.
Jón Daði Böðvarsson (ankle), George Johnston (ankle), George Thomason (knee) and MJ Williams (knee) are all missing for the visitors.
Bolton also have doubts over Cameron Jerome (back), but Victor Adeboyejo is expected to shake off a knock picked up at the weekend.
