Odejayi was lined up as a possible signing ahead of the Championship season but never materialised into anything more than rumours in the tabloids.
However it looks as though Nigel Adkins will finally get his man on an initial one month emergency loan deal on Thursday.
The Nigerian has previously had spells with Forest Green and Cheltenham after leaving Bristol City, with whom he came through the youth ranks.
He joined Barnsley in a £200,000 move in June 2007, with the Scunthorpe Telegraph linking him with a move to Glanford Park before the drawn out move to Oakwell took place.
