Pompey will aim to continue their 100 per cent start to the League One campaign at Bristol Rovers this evening.
A 4-1 victory over Oxford at the weekend means the Blues, Peterborough and Leeds are the only EFL sides yet to drop a point.
Their opponents, meanwhile, lost to the Posh on the opening day and were then beaten at home by Accrington the following week.
They recovered to see off Crawley in the Carabao Cup and then got their first points on the board by winning at Wycombe three days ago.
It leaves Darrell Clarke’s side sitting 16th in the League One standings, as they look to improve on last term’s 13th-placed finish.
Rovers are now in their third season at this level, having dramatically snatched automatic promotion from Accrington’s grasp on the final day of the 2015/16 season.
Pompey looked to be heading for victory when they last visited the Memorial Stadium back on New Year’s Day.
Oli Hawkins had given them a second half lead, only for late goals from Stuart Sinclair and Liam Sercombe to turn the match on its head.
It had been a more straightforward affair at Fratton Park earlier in the campaign, with Hawkins and Brett Pitman (2) on target in a 3-0 victory.
Dion Donohue misses out as he continues his recovery from a groin problem, but Nathan Thompson should be available for selection following a knee injury.
Joe Partington and Stuart Sinclair are both sidelined for the hosts, who could hand appearances to former Pompey players Kyle Bennett and Tareiq Holmes-Dennis.
