Pompey begin a long run of away games when they visit the Keepmoat Stadium to take on Doncaster on Saturday (3pm kick-off).
The postponement of a Fratton fixture with Plymouth at the start of September means the next three league contests are all on the road.
Danny Cowley’s side are hoping to build on their perfect beginning to the campaign, with three successive victories sending them to the League One summit.
Their next opponents, by contrast, are one of a trio of teams yet to collect a single point so far this term.
Rovers have been beaten by AFC Wimbledon, Sheffield Wednesday and Accrington, although did see off Walsall on penalties to reach the second round of the Carabao Cup.
Former Salford boss Richie Wellens took charge of the South Yorkshire outfit in May following the departure of Darren Moore a couple of months earlier.
One of his first acts as manager was to persuade Ben Close to turn down a new contract at Fratton Park and sign for Doncaster.
A last-gasp John Marquis goal was not enough to prevent the Blues from losing 2-1 in last season’s corresponding fixture.
TEAM NEWS
Pompey have doubts over the fitness of Marcus Harness (quad) and skipper Clark Robertson (ankle) after the pair went off injured at half-time on Tuesday night.
Jayden Reid (knee) and Liam Vincent (shin) are definitely missing, while Callum Johnson serves the final game of his suspension.
Former Pompey forward Jordy Hiwula is sidelined for Doncaster, along with Fejiri Okenabirhie and Jon Taylor (all ankle).
Charlie Seaman and Matt Smith are both back in training after periods of self-isolation, with the latter having contracted Covid-19 and the former deemed a close contact.
