All you need to know about League Two clash
Pompey return from a fortnight break when they visit Grimsby on Saturday (3pm kick-off).
Both sides have had two weeks to prepare for the Blundell Park clash following their early exits from the FA Cup.
The Blues are seven places and five points above their 11th-placed opponents, who lost 3-2 at Crawley in their last outing.
But Grimsby have been more successful on the road this season, winning just three times on their own patch.
Leyton Orient (1-2), Crewe (0-2), Hartlepool (0-3) and Cheltenham (0-1) have all left the Mariners’ home with a maximum haul.
Marcus Bignot has been in charge for the past month following the departure of Paul Hurst to Shrewsbury.
His predecessor led Grimsby back into the Football League at the end of last season following a 3-1 victory over Forest Green at Wembley in the play-offs.
They have not met Pompey since both sides occupied the second tier during the 2002/03 campaign.
Mark Burchill scored the only goal as the Blues went top of the table in August, while there was a more comfortable 3-0 victory at Fratton Park in February.
Curtis Main (abdominal) is still sidelined, while Jack Whatmough misses out with a tight hamstring.
A calf problem will deny Ben Davies the chance to play against his former club, while Sam McAllister (groin) and Dominic Vose (thigh) are also out.
