Stephen Henderson has completed his loan move to West Ham.
The Irish goalkeeper, who only joined Pompey in the summer from Bristol City, has signed for the Hammers on loan for the rest of the campaign with a view to a permanent deal in the summer.
Blues administrator Trevor Birch has so far declined to reveal the size of the loan fee for any of the deals that Pompey have struck in a bid to keep the club afloat.
But it is believed the Blues will receive around £700,000 from West Ham for Henderson’s signature, while also further easing the burden on the club’s wage bill.
Henderson’s switch to Upton Park leaves Jamie Ashdown as the only recognised senior goalkeeper at Pompey.
Boss Michael Appleton has yet to decide if he will sign a replacement keeper.
Appleton said: ‘We don’t want to lose our best players, but the situation the club is in doesn’t leave us with many options.
‘Stephen has a fantastic future in the game and this is a good opportunity for him to join a club fighting to win promotion to the Premier League.’
