Two sides in the hunt for automatic promotion meet at Broadhall Way this weekend.
It is Pompey who currently occupy third spot in the League Two standings and hold the upper hand over hosts Stevenage.
The Hertfordshire outfit are seven points further back in 6th position and will be trying to leapfrog Carlisle and Luton on Saturday.
They were in a fine run of form before suffering a 1-0 defeat at play-off hopefuls Blackpool earlier in the week.
That brought to an end a nine-match unbeaten run – stretching back to late January – that included eight victories.
A draw would certainly not be a disaster for the Blues, but only one of the 18 league contests at Broadhall Way this season has ended in a stalemate.
It was Stevenage who came out on top with a 2-1 triumph when the sides met at Fratton Park earlier in the campaign.
But Marc McNulty and Kal Naismith scored to earn Pompey a 2-0 victory when they visited Boro last term.
Curtis Main (knee) and Jack Whatmough (hamstring) are both out for Pompey, while fans will wait to see whether Kyle Bennett (ankle) and Kal Naismith (hamstring) are fit to play.
Veteran goalkeeper Chris Day, 41, is set to deputise for injured Stevenage keeper Jamie Jones, while defender Ron Henry (calf) is a doubt.
