Portsmouth midfielder David Norris has joined Leeds, leaving Pompey with six contracted players.
Earlier this week the cash-strapped League One club revealed they needed to get their eight remaining senior pros off the books or face closure.
Former Plymouth and Ipswich midfielder Norris, 31, has signed a three-year deal and moves on a free transfer.
"Neil Warnock will be delighted to have secured his services," Pompey boss Michael Appleton told the club website.
"He had a fantastic season for us - he was a pivotal part of the team as a midfielder who gets goals and he'll be a real asset to Leeds."
Norris joins former Pompey colleagues James Pearce, and Jamie Ashdown at Elland Road.
Administrator Trevor Birch has said Portsmouth will close on 10 August unless all the senior players left on their books leave the club or reach compromise agreements over their salaries.
Greg Halford, Erik Huseklepp, Liam Lawrence, Dave Kitson, Tal Ben Haim and Kanu remain at the club.
Halford is wanted by Nottingham Forest while Huseklepp and Lawrence are also attracting interest leaving just Ben Haim, Kanu and Kitson.
