Paul Gascoigne could make a guest appearance for Peterborough in their friendly against Leicester on Friday.
The former England midfielder left Boston earlier this week in order to pursue a coaching course at Lilleshall.
Posh boss Barry Fry has offered Gascoigne the chance to maintain his fitness at London Road.
But Fry stressed that he has no plans to bring Gascoigne in permanently, as a player or a coach, despite the recent departure of coach Bobby Gould.
