Pompey will hope to boost their bid to avoid relegation from the Championship when they face fellow strugglers Blackburn Rovers at Fratton Park this afternoon.
John Mousinho’s side are sitting in the bottom three ahead of their clash with the former Premier League champions - but could lift themselves above the dotted line if they can claim three points and Oxford United are beaten in their home game with Preston North End.
Both Mousinho and Rovers counterpart Valerien Ismael have spent the majority of the first half of the season battling with a lengthy injury list and both managers are still facing a sizeable list of absentees ahead of the contest.
Ahead of a potentially pivotal clash, The News takes a look at which players have been ruled out of the Fratton Park meeting and which three could still be available for selection.
