Pompey’s relentless run of games continues with an Easter Monday contest at Morecambe (3pm kick-off).
It will be their third fixture in less than a week, with the previous two resulting in wins over Rotherham and Lincoln.
Their opponents are desperate for points in the fiercely contested battle to beat the drop from League One.
The Shrimps currently have the upper hand, however, and sit three points above that dreaded dotted line.
Derek Adams had left his role as manager after leading the side to fourth tier play-off glory at Wembley last season.
But he returned to replace Stephen Robinson, who departed the Mazuma Stadium to take charge of St Mirren in February.
And Paul Cook’s old sparring partner has helped guide the Lancastrians to three victories from their past four games, including Friday’s 3-2 success at Charlton.
Pompey are looking to triumph on Morecambe’s patch for the first time, having drawn two and lost two of their previous four visits.
They did come out on top when the sides met on the south coast before Christmas, however, courtesy of goals from Marcus Harness and Connor Ogilvie.
Kieron Freeman (ankle), Reeco Hackett (knee) and Jayden Reid (knee) are all still sidelined for Pompey.
Denver Hume (back) is closing in on being available again, while Joe Morrell went off on Friday with a dead leg.
Morecambe defender Ryan McLaughlin could miss out again, having been absent through injury for the past couple of matches.
