Marcus Bean is set to join Wycombe - after snubbing a Pompey deal.
Andy Awford was keen to keep the midfielder at Fratton Park after he impressed during a loan spell from Colchester.
The Blues had tabled a contract until the end of the season in a bid to tie Bean to the club beyond his loan, which expired earlier this week.
Yet the 31-year-old has instead opted to seek a longer deal and is presently finalising a move to League Two leaders Wycombe.
The former Brentford player made six appearances for Pompey, scoring once.
