Should the Foxes wish to bring-in a player on loan - a winger is believed to be the target of manager Nigel Pearson - they will have to finalise the deal before 5pm in order for the player's registration to be successfully updated with the Football League.
Pearson has already mentioned the need for width in his Leicester squad. Only Lloyd Dyer can be named as an out-and-out winger in his large and expensively-assembled squad, although both Paul Gallagher and Jeffrey Schlupp are used to playing on the wing.
Despite a Championship record spending spree believed to top £15 million, Sven Goran Eriksson failed in his attempts to lure Reading winger Jimmy Kebe to the King Power Stadium during the summer. Now new manager Pearson is looking for width and is unlikely to find a solution before the permanent transfer window opens in the New Year.
