Joining Onibuje will be defenders Tom Groves, 19, and James Donovan. Groves is a product of the Nottingham Forest youth system and has England youth honours.
21-year-old Donovan is a Millwall youngster who played a handful of games for Farnborough last season.
Also featuring in the game will be relative unknown Michael Gillian and former Poland u-21 player Pawel Wosniak, who has been training with Accrington Stanley.
Boss Gary Peters told ShrewsWeb: "He [Onibuje] is coming in to play the game so we can take a look at him, there will be five trialists in all.
"Barnsley have put Fola Onibuje's name out as they want other people to know that he's playing. You get that a lot this time of the season with club's and agents putting players names around."
