Crouch put Portsmouth ahead in the 20th, but Michael Turner equalised in the 54th. Glen Johnson restored Pompey's lead with a 25-meter strike nine minutes later.

But Dean Windass equalised in the 86th even though Pompey defender Noe Pamarot appeared to get the final touch when Windass headed a corner from Stelios Giannakopoulos.

If he gets the credit, it will make the 39-year-old striker the Premier League's second oldest scorer.
