Portsmouth will face Sunderland in the League One play-off semi-final after being held at home to a 1-1 draw by Accrington.
Pompey missed out on third place to Charlton on goal difference following their disappointing final-day stalemate.
It could have been worse for Kenny Jackett’s side after the outstanding Sean McConville fired Accrington into a shock lead in the opening minute of the second half.
McConville found the bottom left corner of Craig MacGillivray’s net with a right-footed shot from the edge of the penalty area.
Midfielder McConville had earlier been denied by the crossbar after his first-half looping header had beaten MacGillivray.
Accrington’s opener finally woke Pompey from their slumber and Ben Close drew the hosts level in the 59th minute.
Academy product Close opened up space with a driving run at the Accrington defence before firing home from 20 yards.
Close rattled the crossbar from distance late on as Pompey searched in vain for a late winner.
