Pompey travel to Plymouth this weekend for a clash between two sides that are battling for a play-off place.
It is the hosts who currently hold the upper hand, sitting two places – and one point – above the Blues in fifth, with a game in hand.
A win for either team on Saturday would undoubtedly provide a boost as the finish line draws ever closer.
But with two points separating the five sides hunting for just two spots, nothing will be decided for certain at Home Park.
Whatever the outcome, it has certainly been an incredible turnaround for Argyle, who were pipped to the League Two title by Pompey on the final day of last term.
A 1-0 victory for Kenny Jackett’s troops back in November – courtesy of Kal Naismith’s strike – sent the Pilgrims to the foot of the table.
They have lost just two of the following 20 league fixtures, however, to boost their chances of playing Championship football for the first time since 2010.
It finished all square when the sides last clashed at Home Park in October 2016, with Kyle Bennett and Danny Rose on target in a 2-2 draw.
TEAM NEWS
Anton Walkes misses out with a hamstring injury, while Stephen Henderson (groin) and Danny Rose (leg) are also still sidelined.
Goalkeeper Remi Matthews is a doubt for the hosts after recently becoming a father, with Lionel Ainsworth (back), Simon Church (hip) and Antoni Sarcevic (groin) all out.
Defender Sonny Bradley and striker Ryan Taylor are both expected to feature against their former club.
Ryan Edwards was given the all-clear from doctors earlier in the week, three months after being diagnosed with testicular cancer.
