Huddersfield Town striker Clyde Wijnhard wasted a glorious chance to score the winner two minutes from the end as two sides who shared 13 goals between them on Saturday finished in a stalemate.
Two days after Portsmouth were thrashed 6-0 at Barnsley while Huddersfield were hammering seven past Crystal Palace, a crowd of just over 13,000 endured a game which had precious few chances at either end.
Wijnhard, who scored a hat-trick on Saturday, worked tirelessly throughout for the chance that came to him two minutes from the end - only to see his effort fly over the crossbar.
It was Huddersfield who made the best chances in the second half but neither goalkeeper was busy with Andy Petterson making the best save of the game.
Petterson needed to react sharply when Scott Sellars let fly with a curling right foot effort in the 83rd minute.
Portsmouth's Australian number one did well to get a touch on Sellars' effort, tipping it onto his crossbar and out for a corner.
Rory Allen, a £1million signing from Tottenham, had a quiet first half for the home side but looked more lively in the second period and he could easily have had a hat-trick inside the first five minutes of play after the break.
Allen shot across the face of goal when he should have done better after good work from Stefani Miglioranzi which caused confusion in the Huddersfield defence.
Then an Alan McLoughlin ball sent Allen clear and his right foot shot went just wide.
The former Spurs front man got into a good position moments later to meet a cross from Jeff Peron but Huddersfield goalkeeper Nico Vaesen was never really troubled by the header.
Former Southampton defender Ken Monkou, signed on a three-month contract by Huddersfield after his failure to find a new club elsewhere, was outstanding in his first full game for the Terriers.
Monkou was treated to never-ending abuse from the Portsmouth supporters because of his links with their arch local rivals from The Dell - but his answer was to thwart almost every attack made by Pompey.
