Pompey continued their unbeaten start to the League One campaign with a 2-2 draw against Wycombe.
They fell behind to Bryn Morris' strike before the break, but were much stronger in the second half at a rain-soaked Fratton Park.
Jamal Lowe twice provided pinpoint crosses, with the first converted by Gareth Evans and the second by Brett Pitman.
But Joe Jacobson netted a late penalty following a foul by Christian Burgess to ensure the contest finished all square.
