Pompey welcome Barnsley to Fratton Park this weekend for a clash between two sides chasing promotion to the Championship.
The visitors are trying to get back there at the first attempt after suffering relegation on the final day of last term.
They are doing a good job of achieving that under Daniel Stendel – who took charge over the summer – and have not been beaten in 13 league games.
It has seen them rise up to second in the table, four points clear of Sunderland in third position and five ahead of the Blues.
The Tykes have a better record at Oakwell, but still managed to secure eight league victories on the road this season.
Their most recent away fixture resulted in a convincing 4-1 triumph at Gillingham a fortnight ago, the same result achieved at AFC Wimbledon last month.
Gareth Evans was on target when the sides played out a 1-1 stalemate up north just before Christmas.
You have to go back to 2011 to find the last meeting at Fratton Park, with David Norris and Luke Varney on target in a 2-0 victory.
Andy Cannon (quad), Nathan Thompson (knee) and Jack Whatmough (knee) are all still sidelined for Pompey.
Luke McGee has returned to full training following a wrist injury, but Lloyd Isgrove cannot feature against his parent club.
Barnsley will be without top scorer Kieffer Moore, who has been suffering from concussion, while there is a doubt over Ben Williams (knee).
