Ipswich are hoping to tie up the paperwork on a one-year deal for centre-back Ibrahima Sonko ahead of Saturday's visit of Leeds.
Sonko, released by Stoke at the end of last season, played for Town's reserves on Tuesday and impressed manager Paul Jewell, who wasted little time making his move.
The Tractor Boys boss has been in the market for a central defender all summer and it is hoped Sonko's arrival can be rubber-stamped ahead of the weekend.
Ipswich have conceded 12 times in their last two games and are without the injured Ivar Ingimarsson and suspended Tommy Smith for the visit of Simon Grayson's side.
Former Reading man Sonko, 30, trained with his new team-mates on Thursday morning and would add some much-needed experience to Town's rearguard.
His scheduled arrival comes after that of Michael Chopra and Daryl Murphy, who completed their moves to Portman Road on Thursday and are already in line to feature this weekend.
