Portsmouth are unlikely to delve into the market, but have the option of signing free agents outside the window should they require any additional depth or cover.
But which players are available as free agents? We take a look at some of the exciting options that Kenny Jackett could yet pursue should he wish to seek new recruits:
5. JAKE WRIGHT
Wright, an experienced centre back, was released by Sheffield United on Deadline Day. Oxford fans were calling for Karl Robinson to bring him back to the Kassam Stadium, and a third tier move could well be on the cards. Photo: Charlie Crowhurst
6. ROSS WALLACE
The former Sunderland winger was released by Fleetwood Town in January as the Cod Army looked to free up finance ahead of their winter business. He’s yet to find a new club. Photo: Mike Hewitt
7. BEN ALNWICK
Phil Parkinson revealed that Alnwick was training with Sunderland after leaving Bolton Wanderers. Whether he remains there is unknown, but the stopper could prove an option if League One clubs need to dip into the market. Photo: Laurence Griffiths
8. ROSS McCORMACK
