Winger Erik Huseklepp has departed Portsmouth to leave the troubled League One club with only four senior players.
Huseklepp, 27, joined Pompey from Italian team Bari in August 2011 and has now joined Norwegian club Brann.
Earlier this week, Portsmouth revealed they need to get all of their senior professionals off the club's wage bill
before 10 August or face liquidation.

Jamie Ashdown, Kelvin Etuhu, Marko Futacs, Greg Halford, Stephen Henderson, Erik Huseklepp, Aaron Mokoena, Hayden Mullins, David Norris, Jason Pearce, Luke Varney and Joel Ward.
Senior players remaining:
Tal Ben Haim, Dave Kitson, Kanu and Liam Lawrence
Huseklepp's departure leaves only Tal Ben Haim, Dave Kitson, Liam Lawrence and Kanu remaining at Fratton Park.
Norwegian international Huseklepp was a regular in Portsmouth's first team and scored six goals in 28 appearances before the club's financial problems saw him join Birmingham City on loan in February.
But he has now left English football to sign a four-and-a-half-year deal at Brann, where his career began.
"Erik was a regular in the side before the situation changed dramatically here and he had to go out on loan," Portsmouth manager
Michael Appleton told the club website.
"He was unlucky because after playing regularly for us things didn't quite work out for him at Birmingham.
"I think Erik feels going back to play in Norway will be best for his international career and we wish him well."
